Background

Printing technology has evolved so much over the past decades that customers now want excellent cost management from their imaging devices such as lasers, ink-based and 3D models. Due to these high expectations, customers have begun designing their workflows to focus on the quality of consumables such as printing materials (e.g., toner, ink, powder, and media) for avoiding waste.

Detailed Description

An "imaging device" may be a hardware device, such as a printer, a multifunction printer (MFP), or any other device having functionality to physically produce representations (e.g., text, images, models, etc.) on media. In examples, the "media" may include paper, photopolymer, thermopolymer, plastic, fabric, composite, metal, wood, and the like. In an example, "deposition material" may refer to any material to be deposited by an imaging device. In an example, an imaging device may employ a deposition material to produce a representation on a medium. In such examples, the deposition material may include ink, toner, plastic, polymer, powdered metal, alloy, and the like. In other examples, the deposition material may include a material deposited on the medium but not visible to the user, such as invisible, ultraviolet, or white ink, toner, plastic, polymer, powdered metal, alloy, and the like. In still other examples, the deposition material may include a material used for component cleaning or maintenance. In an example, "printed material" may include deposited material, media, and any other material consumed by a printer.

In some examples, the MFP may perform a combination of a plurality of different functions, e.g., printing, photocopying, scanning, faxing, etc. For example, the function within the image forming apparatus may be to restart the image forming apparatus, troubleshoot the image forming apparatus, update firmware, acquire consumable level information, clone features, adjust security settings, perform tests, acquire scans, perform print requests, clear alerts, and the like.

Many imaging devices lock or secure access to consumables. As used herein, the term "consumable" refers to any printed material of an imaging device and any container that stores such printed material. In some examples, the consumable may contain a deposition material. In some examples, the imaging device may be part of a service contract or part of a subscription plan that is subscribed to or joined by a user of the imaging device. For example, as part of a subscription plan, a user may agree to pay a fee to rent or lease an imaging device for a particular duration. In another example, a user may sign a service contract for a purchased imaging device through which a service technician may perform maintenance and/or repair of the imaging device. Replacement of consumables (such as deposition material) of an imaging device may be incorporated into the cost of some service plans and subscription plans. Premature replacement before all of the material in the consumable is exhausted (such as the consumable still containing deposited material) may increase the operating cost of the imaging device, as any consumable remaining in the consumable may be wasted. Premature replacement of consumables can also increase the environmental impact of such consumables.

To solve these problems, many image forming apparatuses have been developed that lock or secure access to consumables until the consumables are exhausted. However, some users may not have encountered a locked consumable before and may be confused by having no access to a portion of the imaging device that may have been previously accessible. For example, locking access to consumables may make it difficult to clear a paper jam (paper jam) or resolve a malfunction of an image forming apparatus. Some users may damage the imaging device by attempting to access the locked consumables. Some imaging devices may hide or obscure access to locked consumables to prevent users from damaging the imaging device. However, user confusion with inaccessible or hidden consumables can lead to frustration, which can undermine the user experience, increase customer support call rates, and/or create negative impressions for the provider of the service contract/subscription and/or the manufacturer of the imaging device.

To address these issues, in the examples described herein, an imaging device is described that may provide selective access to locked or secured consumables in response to an attempt to access the consumables. In an example, the imaging device may provide feedback to a user that the consumables are locked. In some examples, the user may be prompted to request access to the consumable and may be provided access according to various criteria. In this way, examples described herein may increase user satisfaction with the imaging device.

In an example, the imaging device may detect an attempt to access a locked or locked consumable and, in response, provide feedback that the consumable is locked. In an example, the feedback may be used to indicate that the consumable is locked and explain why the consumable is locked. In some examples, the feedback may explain how to request access to the consumable. In an example, the imaging device may determine whether to provide access to the consumable and whether to unlock the consumable accordingly. In an example, the imaging device may determine whether to provide access based on various policies, permissions, and/or restrictions on providing access to consumables, which may be stored locally on the imaging device or provided by a remote system.

In some examples, the imaging device may monitor whether the consumable has been replaced. In an example, the imaging device may determine whether the consumable being replaced contains any available or useful printing material, and may provide feedback that the consumable was replaced prematurely. In these examples, the user may reinstall the prematurely replaced consumable to avoid waste. Further, in these examples, the service provider may monitor and/or encourage the use of the consumable until exhausted.

Referring now to the drawings, FIG. 1 is a block diagram of an example imaging device 100. In an example, the imaging device 100 may include a lock 120, a feedback engine 132, a lock control engine 134, and a release engine 136 and a component 140. In an example, the imaging device 100 may be coupled to a consumable 110. In an example, the terms "coupled" and/or "coupled" are intended to include suitable indirect and/or direct connections. Thus, if a first component is described as being coupled to a second component, the coupling may be, for example: (1) by direct electrical or mechanical connection; (2) by an indirect electrical or indirect mechanical connection via other devices and connections; (3) through an opto-electrical connection; (4) through a radio connection; (5) a communication connection, and/or (6) other suitable couplings. Rather, the term "connected" is intended to include direct mechanical and/or direct electrical connections. In an example, the imaging apparatus 100 may include a plurality of consumables for different types of printing materials. For example, the image forming apparatus 100 may include consumables selected from among: black deposition material, magenta deposition material, cyan deposition material, yellow deposition material, bonding material, cleaning material, curing material, drying material, and the like.

In an example, the image forming apparatus 100 may include a lock 120 that locks or locks the consumable 110 to the image forming apparatus 100. In an example, a "lock" may refer to any mechanism or coupling by which a first object is secured to a second object and includes a locked state. When the mechanism is engaged to lock the consumable to the printing device, the consumable may be considered to be in a "locked state," locked "or" locked ". In other words, the lock prevents, limits, or inhibits access to the consumable. In an example, the term "unlocking" a lock refers to a mechanism that disengages the lock to unlock a consumable so that the consumable may be removed or decoupled from the imaging device. In an example, the consumable may be locked or in a locked state according to policies, permissions, and/or restrictions provided in the service contract or subscription plan. In such examples, the imaging device may include sensors, detectors, controllers, engines, and/or other mechanisms by which it is determined whether the consumable is empty. In an example, the lock 120 may be a mechanical lock coupled to the mechanical engagement consumable 110 to couple with the imaging device 100. In other examples, lock 120 may be a magnetic component that magnetically couples consumable 110 with imaging device 100. In still other examples, lock 120 may be an electrical component that forms an electrical coupling to electrically couple consumable 110 with imaging device 100. In an example, the lock 120 may secure/un-secure, and/or lock/unlock an intermediate component (such as a door, handle, lever, etc.) to access consumables. In some examples, lock 120 may provide an indication of the locked state to other components of imaging device 100. In other examples, other components of imaging device 100 may determine whether lock 120 is engaged to lock consumable 110 to imaging device 100. In such examples, the imaging device may include sensors, detectors, controllers, engines, and/or other mechanisms by which it is determined whether the consumable is locked.

In an example, imaging device 100 may selectively secure/un-secure, and/or lock/unlock consumables 110 in response to certain parameters. In an example, the parameters may come from policies, permissions, and/or restrictions in a service contract or subscription plan. These parameters may dictate when and under what conditions consumables coupled to the imaging device may be unlocked, disengaged, or released. For example, a service contract or subscription plan may specify that a consumable coupled to an imaging device remains locked while it contains more than a particular amount of printed material or any printed material. In other examples, a service contract or subscription plan may specify how many times a user may access a consumable containing printed material (i.e., a non-empty consumable) for a given period of time. In another example, a service contract or subscription plan may provide a duration of access to non-empty consumables (e.g., 15 minutes). In these examples, a user may decouple consumable 110 from imaging device 100 during a particular time period. In other words, the service contract or subscription plan may specify that any access provided to the consumable 110 may be timed out. In some examples, a service contract or subscription plan may specify that locked consumables may be accessed for a fee. In one such example, any such additional cost may be refundable if the same consumable is returned to the imaging device rather than being replaced with a different consumable. In such an example, the service provider or subscription plan may encourage the user to use the consumable until it is empty rather than prematurely replacing the consumable with a replacement consumable.

In an example, the imaging device 100 includes at least the engine 132, the engine 134, and the engine 136, and the engine 132, the engine 134, and the engine 136 may be any combination of hardware and programming to implement the functions of the execution engine. In the examples described herein, this combination of hardware and programming can be implemented in a number of different ways. For example, the programming of the engine may be processor-executable instructions stored on a non-transitory machine-readable storage medium, and the hardware of the engine may include processing resources to execute those instructions. In such examples, the machine-readable storage medium may store instructions that, when executed by the processing resource, implement engine 132, engine 134, and engine 136. In such examples, imaging device 100 may include a machine-readable storage medium storing instructions and a processing resource executing the instructions, or the machine-readable storage medium may be separate but accessible to imaging device 100 and the processing resource.

As used herein, a "machine-readable storage medium" may be any electronic, magnetic, optical, or other physical storage device that contains or stores information such as executable instructions, data, and the like. For example, any of the machine-readable storage media described herein can be any of Random Access Memory (RAM), volatile memory, non-volatile memory, flash memory, a storage drive (e.g., a hard drive), a solid state drive, any type of storage disk (e.g., a compact disk, a DVD, etc.), the like, or a combination thereof. Further, any of the machine-readable storage media described herein may be non-transitory.

In some examples, the instructions may be part of an installer package, which when installed may be executed by a processing resource to implement engine 132, engine 134, and engine 136. In such examples, the machine-readable storage medium may be a portable medium, such as a CD, DVD, or flash memory, or a memory that may be maintained by the imaging device, through which the installation package may be downloaded and installed. In other examples, the instructions may be part of an application, a plurality of applications, a component, or a plurality of components that have been installed on the imaging device 100 that includes the processing resource. In such examples, the machine-readable storage medium may include a memory, such as a hard disk drive, a solid state drive, or the like. In other examples, the functionality of any engine of imaging device 100 may be implemented in the form of circuitry.

In the example of fig. 1, the feedback engine 132 may selectively generate a signal to control the component 140 in response to the initiating event 105. In such an example, feedback engine 132 may selectively generate a signal to control component 140 when consumable 110 is locked. In an example, the imaging device 100 may include any number of sensors or detectors to detect the priming event 105 and provide the priming event 105 to the feedback engine 132. In some examples, feedback engine 132 may determine whether consumable 110 is locked by communicating with lock 120 and/or consumable 110. In an example, a "start event," "consumable unlock event," or "unlock event" may refer to an attempt to access a consumable directly or indirectly. For example, when a user activates a mechanism through which access to consumable 110 may be provided in imaging device 100, a start event or a consumable unlock event may occur. In an example, the mechanism by which access to the consumable may be provided may include a door, button, handle, or the like. In an example, the gate to the consumable 110 may be a gate that directly provides access to the consumable 110, or an intermediate gate that provides access to another portion of the image forming apparatus 100 through which the consumable 110 may be accessed. In an example, the buttons may be physical buttons or virtual buttons (such as buttons displayed on a display) to provide access to the consumables 110 directly or indirectly. For example, the button may open a hatch or door to access consumable 110. In an example, the handle may be a handle that directly provides access to the consumable 110, or an intermediate handle that provides access to another portion of the imaging device 100 through which the consumable 110 may be accessed.

In an example, the component 140 can be any component that provides user feedback. In an example, the component 140 may be selected from a speaker, a display, a light source, a vibration component, or a combination thereof to provide feedback or instructions to the user. In an example, the speaker may output an audio signal or instruction to the user to notify them that consumable 110 is locked. In some examples, the audio signal or instruction may command or instruct the user to view a display or other portion of the imaging device containing further instructions. In an example, the display may display a graphical user interface or other visual signal through which a user may receive instructions and/or prompts to interact with the imaging device 100. In an example, the light source may be any type of light emitting device visible to a user that is coupled to the imaging device 100. In an example, the light source may flash or change color to indicate to the user that the consumable 110 is locked. In some examples, the light source may illuminate a hole for indication (cutout) or other indicator of the locked status of the consumable 110. In an example, the vibration assembly may provide a tactile signal to the user to indicate the locked state of the consumable 110. In such an example, the vibration assembly may vibrate to indicate to the user that the consumable 110 is locked. For example, the vibration component may be arranged to vibrate a mechanism (such as a door, handle, button, etc.) for accessing the consumable 110. In some examples, the component 140 may further provide feedback as to why the consumable is locked and how access to the consumable may be obtained. In this way, user confusion can be reduced to improve user satisfaction with the imaging apparatus.

In an example, lock control engine 134 may determine whether priming event 105 is approved to unlock consumable 110. In an example, lock control engine 105 may determine whether to approve initiation event 105 based on various factors. In an example, the lock control engine 134 may generate or provide the disengagement authorization 107 for the release engine 136. "Release authorization" may refer to an instruction to approve a start event, and may further include parameters regarding terms of access to the consumable. In an example, lock control engine 134 may determine that initiation event 105 is approved according to policies, permissions, and/or restrictions provided in a service contract or subscription plan subscribed to or joined by a user of imaging device 100. For example, a policy may allow 15 minutes of access to the consumable per week for cleaning. In another example, the permissions may allow access to the imaging device by a technician or maintenance work. In yet another example, the restriction may define access to non-empty consumables coupled to the imaging device unless a specific license is granted by the remote system to access the consumables. In some examples, lock control engine 134 may determine that start event 105 is approved based on information stored locally on imaging device 100. In such an example, lock control engine 134 may determine disengagement authorization 107 based on policies, permissions, or restrictions stored in non-volatile memory of imaging device 100. In other examples, lock control engine 134 may receive approval of initiating event 105 from a remote device or remote system (either passive (e.g., acquisition) or active (e.g., retrieval)). In one such example, lock control engine 134 may receive detach authorization 107 from a remote system. In other examples, lock control engine 134 may receive or access policies, permissions, or restrictions stored in a remote device or remote system to determine whether to approve initiating event 105. In an example, the imaging device 100 may include a communication unit or communication component that communicates with a remote device or remote system.

In an example, lock control engine 134 may determine that a start event 105 of accessing consumable 110 is not approved based on various factors. In an example, lock control engine 134 may determine that the activation event is not approved according to policies, permissions, and/or restrictions provided in a service contract or subscription plan subscribed to or joined by the user of imaging device 100. In such an example, lock control engine 134 may provide feedback engine 132 with a notification that the determination of initiating event 105 is not approved. In such examples, feedback engine 132 may control components 140 of imaging device 100 to provide feedback that access to consumable 110 is denied via visual feedback, audio feedback, vibratory feedback, or a combination thereof. In some examples, feedback engine 132 may further control component 140 to provide feedback of options by which to request access to consumable 110. For example, in response to determining that a start event to access a non-empty consumable is not permitted according to a service plan or subscription plan, components of the imaging device 100 may provide an option to gain access to the consumable for an additional fee. For example, the display may provide buttons represented by images for requesting access to the consumables 110 and warnings that access to the consumables may result in incurring additional costs. In this example, if the consumable 110 is returned to the image forming apparatus 100 without being replaced, the additional fee may be refundable.

In an example, the release engine 136 may unlock or disengage the lock 120 in response to approval of the initiating event 105. In an example, the release engine 136 may disengage the lock 120 in response to receiving the disengagement authorization 107. In an example, when lock 120 is disengaged or unlocked, consumable 110 may be decoupled from imaging device 100. In other words, release engine 136 may control lock 120 to selectively provide access to decoupled consumables 110 from imaging device 100. In an example, the release engine 136 may receive (either passive (e.g., request) or active (e.g., fetch)) the detach authorization 107 from the lock control engine 134. In an example, release engine 136 may control lock 120 to provide access to consumable 110 according to a parameter (such as a particular duration) provided in disengagement authorization 107. In such an example, a user may access the consumable 110 decoupled from the imaging apparatus 100 during a particular duration.

Fig. 2 is a block diagram of an example imaging device including possible additional example components of imaging device 100 of fig. 1. Additional components may include a communication engine 138, an authorization engine 139, a speaker 142, a display 144, a light source 146, and a vibration component 148. The communication engine 138 and the authorization engine 139 may be any combination of hardware and programming to implement the functionality of the engines such as the engines 132, 134, and 136 described above with reference to fig. 1.

The communication engine 138 may be used to communicate with a remote system 200. In an example, the remote system 200 may include devices or components that communicate with the communication engine 138 via any communication protocol (e.g., Transmission Control Protocol (TCP) and Internet Protocol (IP), WiFi direct, bluetooth, etc.). In an example, the communication engine 138 can transmit the detection of the start event 105. In such an example, the communication engine 138 may receive the detach authorization 107 from the remote system 200 in response to transmission of the initiating event 105. In another such example, communication engine 138 may receive updated policy, permission, and/or restriction information from remote system 200, and lock control engine 134 may determine whether to approve initiating event 105 from the updated policy, permission, and/or restriction information. In other examples, communication engine 138 may transmit information received from component 140. For example, communication engine 138 may transmit a request to remote system 200 for additional information regarding incurred fees received from display 144 for accessing consumable 110.

In an example, the authorization engine 139 may determine whether consumables have been replaced in the imaging device 100. In an example, the authorization engine 139 may control or communicate with any sensor, detector, or engine to determine whether a consumable has been replaced. For example, the authorizing engine 139 may determine that a consumable has been replaced by comparing consumable identification information provided by the consumable with a previously stored value. In an example, the authorization engine 139 may provide a "consumable replacement notification" 109. In an example, the consumable replacement notification refers to a notification that provides information about a replacement state of a consumable coupled to the image forming apparatus. In an example, the consumable replacement notification may indicate whether the consumable has been replaced in the image forming apparatus. In some examples, the consumable replacement notification may be provided or generated by the authorizing engine 139 after access to the consumable 110 has been provided by the release engine 136.

In some examples, the consumable replacement notification may further include "consumable level information" about the consumable. As used herein, "consumable level information" refers to information indicative of the amount of printed material in a consumable and any other information captured by an imaging device about the consumable. In an example, the consumable level information may indicate whether the consumable is empty. In such an example, the consumable level information may indicate an amount of remaining printed material in the consumable. In an example, consumable level information may be provided by consumable 110 to authorization engine 139. In other examples, the consumable level information may be determined by monitoring usage of printing material used by the image forming apparatus 100 (e.g., by counting the number of printed sheets).

In an example, authorization engine 139 provides consumable replacement notification 109 to lock control engine 134. In such an example, lock control engine 134 may determine whether the user should be provided with further feedback regarding any replacement consumables according to the policies, permissions, and restrictions available to lock control engine 134. In one such example, the lock control engine 134 may provide instructions to the feedback engine 132 to control the display 144 to display a graphical user interface with a warning that the non-consumable material has been replaced. In other examples, authorization engine 139 may provide consumable replacement notification 109 to communication engine 138 for transmission or transmission to remote system 200. In one such example, remote system 200 may provide instructions for any additional feedback to be provided by component 140 via communication engine 138.

Fig. 7A to 7B are examples of consumable part replacement notifications of an example image forming apparatus. In the example of fig. 7A, the consumable replacement notification 709A includes the consumable identification number and consumable level information of the first consumable and the consumable identification number and consumable level information of the second consumable. In an example, the first consumable may be a consumable initially coupled to the imaging device, and the second consumable may be a consumable coupled to the imaging device after releasing the engine to disengage a lock of the imaging device to provide access to the consumable. In the example of FIG. 7A, the first consumable and the second consumable appear to be the same because the consumable identifiers appear to match. In some examples, the imaging device may provide a consumable replacement notification to a remote system. In one such example, the imaging device may provide a consumable replacement notification to a remote system when the consumable has been replaced.

In the example of fig. 7B, the consumable replacement notification 709B includes the consumable identification number and consumable level information of the first consumable and the consumable identification number and consumable level information of the second consumable. In the example of FIG. 7B, the first consumable appears to have been replaced by the second consumable because the consumable identification appears to be mismatched. In such an example, the imaging device may determine whether to provide additional feedback to the user based on policies, permissions, and/or restrictions available to the imaging device. In some examples, the additional feedback provided by the imaging device may include warnings that non-consumable materials were removed and should be returned to the imaging device. In other examples, the additional feedback provided by the imaging device may include an estimated charge for premature removal of non-empty consumables. In this way, the additional feedback may encourage the user to use the consumable until it is empty rather than prematurely replacing it with a replacement consumable. In some examples, the additional feedback may be received from the remote system via the communication engine. In an example, the imaging device may provide additional feedback via components controlled by a feedback engine.

Referring again to fig. 2, in an example, the speaker 142 of the component 140 can provide feedback to the user. In an example, the feedback engine 132 may control the speaker 142 to provide feedback when the start event 105 is detected or received in the imaging device 100. In an example, the speaker 142 may output an audio signal. In an example, the audio signal may be a sound such as a ring tone, a beep, or the like, to gain the user's attention. In other examples, the audio signal may include an audio instruction to the user to notify them that consumable 110 is locked. In some examples, the audio signal may command or indicate how to obtain additional information about the lock status. For example, the audio signal may instruct the user to view the display 144 or other portion of the imaging device containing further instructions. In still other examples, the audio signal may include a combination of sound and audio instructions.

Fig. 3A to 3B are examples of speakers of an example imaging apparatus. In the example of FIG. 3A, imaging device 300A is shown with a door 350A to access consumables. In an example, when a user attempts to access the door 350A (i.e., a start event), a feedback engine (not shown) of the imaging device 300A may control the speaker 342A to emit an audio signal. In the example of FIG. 3A, a lock control engine (not shown) may determine that the initiating event is approved. In such an example, the audio signal may say "you are accessing the locked consumable. Additional fees may be charged. For more information, please refer to the display panel. ". In the example of FIG. 3B, imaging device 300B is shown with button 350B having access to door 350A of the consumable. In an example, when a user actuates button 350B (i.e., a start event), a feedback engine (not shown) of imaging device 300B may control speaker 342B to emit an audio signal. In the example of FIG. 3B, a lock control engine (not shown) may determine that the initiation event is not authorized for access to the consumable. In such an example, the audio signal may be a warning sound, such as "deny access," following the audible instruction. Please refer to the display. ".

Referring again to fig. 2, in an example, the display 144 of the component 140 can provide feedback to the user. In an example, the feedback engine 132 may control the display 144 to provide feedback when a start event 105 is detected or received in the imaging device 100. In an example, the display 144 may display a visual signal, such as a graphical user interface, by which a user may receive instructions and/or prompts to interact with the imaging device 100. In an example, display 144 may display a graphical representation of a button for requesting access to consumable 110 on a graphical user interface. In other examples, display 144 may display information about the lockout status of consumable 110 via a graphical user interface. For example, the lockout status information may explain why the consumable 110 is locked, and/or how to access the consumable 110.

Fig. 4A to 4B are examples of layouts of displays of an example imaging apparatus. In the example of fig. 4A, the start event has been received by a feedback engine (not shown) of the imaging device 400A. In response to the start event, the feedback engine controls the display 444A to display the graphical user interface 460A. In the example of FIG. 4A, the graphical user interface 460A depicts a warning that the consumable is locked. The alert includes a graphical representation of the button 462A for requesting access to the locked consumable. In an example, the content of the alert may be determined according to a service contract or subscription plan.

In the example of fig. 4B, the start event has been received by a feedback engine (not shown) of the imaging device 400B. In response to the start event, the feedback engine controls the display 444B to display the graphical user interface 460B. In the example of FIG. 4B, the graphical user interface 460B depicts a warning that the consumable is locked. The alert includes a graphical representation of the button 462B for requesting access to the locked consumable. In the example of FIG. 4B, the warning of graphical user interface 460B indicates that access to the locked consumables will be provided and that additional fees may be charged. In such an example, a lock control engine (not shown) of the imaging device 400B may determine that the start event is approved to access the locked consumables. If the user actuates button 462B, imaging device 400B may disengage the lock to provide access to the consumables. In such an example, if the consumable is returned to the image forming apparatus 400B after being removed, the authorization engine may determine whether the consumable is replaced. If a new consumable is detected by the authorizing engine in the image forming apparatus 400B, the communication engine (not shown) may provide a consumable replacement notification with consumable level information of the currently and previously installed consumables to the remote system (as described with reference to fig. 7A to 7B). In such an example, the remote system or an administrator thereof may determine whether to charge the user for any premature replacement of the consumable. In other examples, imaging device 400B may determine whether to charge the user for any premature replacement of the consumable. In some examples, the feedback engine of imaging device 400B may control display 444B to display additional feedback information about the replacement of the consumable via a graphical user interface.

Referring again to fig. 2, in an example, the light source 146 of the assembly 140 may provide feedback to the user. In an example, the feedback engine 132 may control the light source 146 to provide feedback when the start event 105 is detected or received in the imaging device 100. In an example, the light source 146 may be any type of light emitting device that emits visible light to a user. In an example, the light source 146 may flash or change color to indicate to the user that the consumable 110 is locked. In some examples, the light source 146 may illuminate an indicator hole or other indicator of the locked status of the consumable 10. In some such examples, the light source 146 may illuminate an indicator to instruct a user to view the display 144 or other portion of the imaging device containing further instructions. In other such examples, the light source 146 may illuminate a button or other physical object to provide access to the consumable.

Fig. 5A to 5B are examples of light sources of an example imaging apparatus. In the example of FIG. 5A, imaging device 500A is shown with a door 550A to access consumables. In an example, when a user attempts to access the door 550A (i.e., a start event), a feedback engine (not shown) of the imaging device 500A may control a light source (not shown) to illuminate a lock and key symbol 570 and/or a button 575 disposed on the door 550A. In an example, button 575 may indicate that actuation of button 575 is a request for access to a locked consumable. In the example of FIG. 5A, a lock control engine (not shown) may determine that a start event providing access to a consumable is not approved. In such an example, the feedback engine of the imaging device 500A may control the light source to illuminate the lock and key symbol 570. In another example of FIG. 5A, a lock control engine (not shown) may determine that a start event providing access to a consumable is approved. In such an example, the feedback engine of the imaging device 500A may control the light sources to illuminate the lock and key symbol 570 and the button 575 sequentially or simultaneously. In such an example, the user may be notified that the consumable is locked and provided with the ability to request access to the consumable from a location disposed on the door 550A to access the consumable of the image forming apparatus 500A.

In the example of FIG. 5B, imaging device 500B is shown with button 550B to access consumables. In an example, when a user activates the button 550B (i.e., a start event), a feedback engine (not shown) of the imaging device 500B may control the light source 572 to flash or illuminate in response to detection or receipt of the start event. In the example of fig. 5B, the light source 572 may illuminate a particular color or remain continuously illuminated when the consumable is in the locked state. The color or illumination pattern of the light source 572 may be changed in response to actuation of the button 550B. For example, the light source 572 may blink at a particular frequency in response to a start event when the consumable is in a locked state, and may subsequently blink at a different frequency if the start event is approved by the lock control engine of the imaging device 550B. In another example, the light source 572 may be red in response to a start event when the consumable is in a locked state, and may change color to green if the start event is approved by the lock control engine of the imaging device 550B.

Referring again to fig. 2, in an example, the vibration assembly 148 may provide feedback to the user. In some examples, the vibration assembly may be a vibration motor, a micro-vibration motor, or the like. In an example, the feedback engine 132 may control the vibration assembly 148 to provide feedback when a start event 105 is received or detected in the imaging device 100. In an example, the vibration assembly 148 may provide a tactile signal to the user to indicate the locked status of the consumable 110. In such an example, vibration assembly 148 may vibrate to indicate to the user that consumable 110 is locked. For example, vibration component 148 may be configured to vibrate a mechanism (such as a door, handle, button, etc.) for accessing consumable 110. In an example, the frequency, duration, or intensity of the vibration may be varied according to whether access to the locked consumable is granted or denied by the lock control engine 134.

Fig. 6A to 6B are examples of a vibration member of an example image forming apparatus. In the example of fig. 6A, imaging device 600A is shown with a door 650A to access consumables and a vibrating assembly 680A (depicted in dashed lines) disposed within door 650A or behind door 650A to vibrate door 650A. In the example of fig. 6A, when the consumable is in a locked state, the vibrating assembly 680A may vibrate in response to an attempt to open the door 650A (i.e., a start event). In such an example, when the lock control engine of the imaging device 650A determines that the start event is approved, the vibrating component 680A may cease vibrating to indicate that access to the door 650A has been granted.

In the example of fig. 6B, imaging device 600B is shown with a handle 650B to access consumables and a vibrating assembly 680B (depicted in dashed lines) disposed within or behind handle 650B to vibrate handle 650B. In the example of fig. 6B, the feedback engine may control the vibration assembly 680B to vibrate the handle 650B in response to an activation event with respect to the handle 650B. In such an example, when the lock control engine of imaging device 650B determines that the start event is not approved, vibrating component 680B may vibrate at a greater intensity or frequency to indicate that access to the consumable has been denied.

Fig. 8A-8B are flowcharts of an example method of providing access to consumables coupled to an imaging device. Although execution of method 800 is described below with reference to imaging device 100 of fig. 2 above, other suitable systems for execution of method 800 may be utilized. Thus, implementation of method 800 is not limited to such an example.

At 802 of method 800, the imaging device 100 may detect a consumable unlock event or start event 105. In an example, any number of sensors or detectors may detect a start event or a consumable unlock event. In an example, the consumable unlocking event may be the activation of a lock 120 to access the consumable 110, for example, by pressing a button as shown in fig. 5B by way of non-limiting example.

At 804, the image forming apparatus 100 may determine whether the consumable 110 is locked. In an example, the lock 120 may provide an indicator of the locked state to the imaging device 100. In other examples, feedback engine 132 may determine the lock state of lock 120.

At 806, in response to determining that the consumable 110 is locked, the imaging device 100 may activate the component 140 to indicate that the consumable 110 is locked. In an example, any one of speaker 142, display 144, light source 146, vibration assembly 148, or a combination thereof may be activated to indicate that consumable 110 is locked.

At 808, the imaging device 100 may receive the detachment authorization 107. In an example, lock control engine 134 may determine whether priming event 105 is approved and may generate or provide disengagement authorization 107 when priming event 105 is approved. In some examples, lock control engine 134 may determine that start event 105 is approved based on policies, permissions, and/or restrictions stored locally on imaging device 100 or remotely (such as in remote system 200). In other examples, lock control engine 134 may receive disengagement authorization 107 from remote system 200 via communication engine 138.

At 810, imaging device 100 can unlock consumable 110 in response to disengaging authorization 107. In such an example, the release engine 136 may unlock the lock 120 or disengage the lock 120 in response to the disengagement authorization 107 received from the unlock engine 134. In such an example, once the lock 120 is disengaged, the consumable 120 may be decoupled from the imaging device 100.

FIG. 8B is a flowchart of an example method 900 for consumable access to an imaging device, which may be incorporated into the flowchart of FIG. 8A at A. Although execution of the method of fig. 8B is described below with reference to the imaging apparatus 100 of fig. 2 and the flowchart of fig. 8A described above, other suitable systems for execution of the method of fig. 8B may be utilized. Thus, implementation of the method of fig. 8B is not limited to such an example.

At 902 of method 900, the image forming apparatus 100 determines whether the consumable 110 has been replaced. For example, in the imaging device 100, the authorization engine 139 may determine whether the consumable has been replaced.

At 904, imaging device 100 may send consumable replacement notification 109 to remote system 200 in response to determining that the consumable has been replaced. In an example, the consumable replacement notification 109 may include consumable level information to indicate an amount of useful, unused, or remaining printed material in the consumable being replaced. In an example, authorization engine 139 may provide consumable replacement notification 109 to communication engine 138 for transmission to remote system 200.

Although the flowcharts of fig. 8A through 8B show a specific order of execution of certain functions, the flowcharts of fig. 8A through 8B are not limited to this order. For example, functions illustrated in succession in the flowchart may be executed in a different order, concurrently or with partial concurrence, or with a combination thereof. In some examples, the functionality described herein with respect to fig. 8A-8B may be provided in conjunction with the functionality described herein with respect to any of fig. 1-7B and 9.

FIG. 9 is an example of a system to unlock consumables. In the example of fig. 9, computing device 1000 includes processing resource 1100 and machine-readable storage medium 1200 including instructions 1210, 1220, 1230, 1240, 1250, and 1260 executable by (e.g., encoded as) processing resource 1100. In some examples, storage medium 1200 may include additional instructions. In some examples, instructions 1210, 1220, 1230, 1240, 1250, 1260, and other instructions described herein with respect to storage medium 1200 may be stored on a machine-readable storage medium remote from computing device 1000 and processing resource 1100, but accessible by computing device 1000 and processing resource 1100 (e.g., via a computer network). In some examples, instructions 1210, 1220, 1230, 1240, 1250, and 1260 may be instructions of a computer program, a computer application (app), a proxy, etc., of imaging device 100 of fig. 1 and 2. In other examples, the functionality described herein with respect to instructions 1210, 1220, 1230, 1240, 1250, and 1260 may be implemented as an engine including any combination of hardware and programming to implement the functionality of the engine, as described below.

In examples described herein, a processing resource may include one or more processors, for example, included in a single computing device (as shown in fig. 9) or distributed across multiple computing devices. The "processor" may be at least one of a Central Processing Unit (CPU), a semiconductor-based microprocessor, a Graphics Processing Unit (GPU), a Field Programmable Gate Array (FPGA) to fetch and execute instructions, other circuitry adapted to fetch and execute instructions stored on a machine-readable storage medium, or a combination thereof. The processing resource 1100 may fetch, decode, and execute instructions stored on the storage medium 1200 to perform the functions described below. In other examples, the functionality of any of the instructions in the storage medium 1200 may be implemented in the form of circuitry, in the form of executable instructions encoded on a machine-readable storage medium, or in the form of a combination thereof.

In the example of fig. 9, the instructions 1210 may receive an unlock event 1005 from an imaging device. In an example, the unlock event 1005 may be the activation of a lock or other mechanism by which to access consumables of the imaging device.

Instructions 1220 may determine whether the consumable is locked to the imaging device. In an example, the consumable may be directly locked to the imaging device via the lock. In other examples, the consumable may be indirectly locked to the imaging device via, for example, a locking door or other access mechanism.

The instructions 1230 may cause the component to activate to indicate that the consumable is locked in response to determining that the consumable is locked to the imaging device. In an example, the activating can selectively activate a speaker to play an audio file, a display to display a notification of a locked state, a light emitting component to emit light, and a vibration component to vibrate, or a combination thereof.

The instructions 1240 may unlock the consumable in response to disengaging the authorization. In an example, unlocking the consumable may include actuating a lock to provide access to the consumable or any intermediate door or mechanism that prevents a user from accessing the consumable.

Instructions 1250 may determine whether the consumable has been replaced. In an example, a determination of replacement of the consumable may be made when the consumable is decoupled from and returned to the imaging device.

The instructions 1260 may transmit a consumable replacement notification in response to determining that the consumable has been replaced. In an example, the consumable replacement notification includes a consumption level indication indicating an amount of unused deposition material in the consumable. In other examples, the consumable replacement notification includes instructions to display a notification that a non-empty consumable has been replaced.

All of the features disclosed in this specification (including any accompanying claims, abstract and drawings), and/or all of the steps of any method or process so disclosed, may be combined in any combination, except combinations where at least some of such features and/or steps are mutually exclusive.
