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, "media" may include paper, photopolymers, thermopolymers, plastics, composites, metals, wood, and the like. In some examples, the MFP may be capable of performing a combination of a number of different functions, such as printing, photocopying, scanning, faxing, and the like. For example, the functions within the image forming apparatus may be rebooting the image forming apparatus, servicing the image forming apparatus, upgrading firmware, acquiring consumable level information, copying features, adjusting security settings, performing tests, acquiring scans, performing print requests, clearing alarms, and the like.

The imaging device may be a laser imaging device including a photosensitive element for transferring the deposition material to the medium. In other examples, the imaging device may be an inkjet imaging device including a fluid ejection device for dispensing a fluid (e.g., ink, developer fluid, etc.). In some such examples, the fluid ejection device may include one or more fluid ejection dies. In some examples, the fluid ejection die may reciprocate across a span of media traveling through the imaging device. In other examples, a plurality of fluid ejection dies may be arranged in an array to span the span or width of a medium traveling through an imaging device (i.e., a page wide array).

In an example, the imaging device may execute a start-up routine to test and/or configure the imaging device for use. In some example imaging devices, the start-up routine may include a step or operation to clear printed material. As used herein, "printing material" refers to any material that may be used by an imaging device, such as ink, toner, paper, and the like. In such examples, the imaging device may purge fluids (e.g., transport fluids, developer fluids, inks, etc.) contained in the imaging device during a start-up routine. It has been observed that the quality of a print job may be reduced if such purging occurs in a temperature environment that is too cold. For example, printing after or as part of a start-up routine in an environment that is too cold may result in artifacts appearing on the print job.

To address these issues, in the examples described herein, the imaging device may power up, energize, or activate a fan and/or heating element of the imaging device to increase the internal temperature of the imaging device prior to a purge operation of the device. In such an example, the imaging device may determine whether an internal temperature of the imaging device is less than a threshold temperature. In an example, a start-up routine of the imaging apparatus is suspended or stopped at least before the purge operation. In an example, if the outside temperature is greater than the inside temperature, the imaging device may activate a fan to circulate or divert outside air into a chassis of the imaging device. In other examples, the imaging device may activate a heating element of the imaging device. In still other examples, the imaging device may activate a heating element and a fan of the imaging device. In this manner, the examples described herein may increase the internal temperature of the imaging device, which may reduce the occurrence of artifacts in a print job.

Referring now to the drawings, FIG. 1 is a block diagram of an example imaging device 100 that changes the internal temperature of the imaging device. In the example of fig. 1, imaging device 100 includes a processing resource 110 and a machine-readable storage medium 120 including instructions 122, 124, 126, 128, 130, 132, and 134 (e.g., encoded with instructions 122, 124, 126, 128, 130, 132, and 134) executable by processing resource 110. In some examples, storage medium 120 may include additional instructions. In some examples, instructions 122, 124, 126 and 128, 130, 132, 134, as well as any other instructions described herein with respect to storage medium 120, may be stored on a machine-readable storage medium that is remote from imaging device 100 and processing resource 110, but accessible to imaging device 100 and processing resource 110 (e.g., via a computer network). In some examples, the instructions 122, 124, 126, 128, 130, 132, and 134 may be instructions of a computer program, a computer application ("app"), an agent, etc. of the imaging apparatus 100. In other examples, the functionality described herein with respect to instructions 122, 124, 126, 128, 130, 132, and 134 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, the processing resources may include one processor or multiple processors, for example, included in a single imaging device (as shown in fig. 1) or distributed across multiple imaging 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 electronic circuitry adapted to fetch and execute instructions stored on a machine-readable storage medium, or a combination thereof. The processing resource 110 may fetch, decode, and execute instructions stored on the storage medium 120 to perform the functions described below. In other examples, the functionality of any instructions of storage medium 120 may be implemented in the form of electronic circuitry, in the form of executable instructions encoded on a machine-readable storage medium, or a combination thereof.

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 one or combination of Random Access Memory (RAM), volatile memory, non-volatile memory, flash memory, a storage drive (e.g., a hard disk drive), a solid state drive, any type of storage disk (e.g., optical disk, DVD, etc.), and the like. Further, any of the machine-readable storage media described herein may be non-transitory.

in the example of fig. 1, instructions 122 may determine whether a start-up routine is to be initiated in imaging device 100. As used herein, a "start-up routine" refers to a routine that is executed by an imaging device when it is booted, changes power states, or in response to an event. The routine may include one or more operations to be performed by the imaging device. In an example, the imaging device may manually initiate the start-up routine or automatically initiate the start-up routine. In an example, the imaging device 100 may manually initiate a start-up routine in response to a request to boot the imaging device. In such examples, the imaging device 100 manually initiates the start-up routine in response to a signal received through a user interface (e.g., a switch, button, user interface, etc.). In an example, an imaging device may automatically initiate a start-up routine in response to an event. In some examples, the event may be when power is provided to the imaging device. In other examples, the event may be when a power state of the imaging device changes (e.g., from a sleep mode to an awake mode, etc.). In yet another example, the event may be the receipt of a job request.

in instruction 124, the internal temperature 105 of the imaging device 100 may be obtained. In an example, the internal temperature 105 of the imaging device 100 may be a temperature inside a chassis of the imaging device 100. In some examples, the internal temperature 105 may be obtained from a temperature sensor inside the chassis of the imaging device 100. In one such example, the internal temperature sensor may be disposed in a fluid ejection device of the imaging device 100. In such an example, the temperature sensor may be a temperature sensing resistor. In another example, the temperature sensor may be a sensor that measures the temperature of a consumable coupled to the imaging device 100. In an example, the internal temperature 105 may be obtained as part of a start-up routine performed by the imaging device 100. In other examples, the internal temperature 105 may be obtained in response to a particular event. In one such example, the internal temperature 105 may be obtained at a particular time. In another such example, the internal temperature 105 may be obtained in response to a change in a power state of the imaging apparatus 100 (e.g., from a sleep mode to a wake mode).

in the following discussion and claims, the term "coupled" is intended to include indirect and/or direct connections as appropriate. Thus, if a first component is described as being coupled to a second component, that coupling may be, for example: (1) by direct electrical or mechanical connection, (2) by indirect electrical or mechanical connection via other devices and connections, (3) by optical electrical connection, (4) by wireless electrical connection, and/or (5) another suitable coupling. Rather, the term "coupled" is intended to include direct mechanical and/or electrical connection.

In instruction 126, the imaging device 100 may determine whether the internal temperature 105 is below a threshold temperature. In an example, the threshold temperature may be a particular temperature stored in the imaging apparatus 100. In other examples, the threshold temperature may be variable depending on various characteristics of the imaging device and any consumables coupled thereto. As used herein, the term "consumable" refers to any printed material of an image forming apparatus and any container that stores such printed material. For example, the consumable may be a toner cartridge coupled to a laser imaging device or a cartridge coupled to an inkjet imaging device. In an example, the threshold temperature may be determined according to a characteristic of a consumable coupled thereto. In such examples, the threshold temperature may be determined according to the type of consumable coupled to imaging device 100 (e.g., a cartridge or toner cartridge) and the size (e.g., the volume of toner or ink contained in the cartridge). In some such examples, the threshold temperature may be determined by imaging device 100. In other such examples, the threshold temperature may be obtained by the imaging device 100. For example, the threshold temperature may be obtained from a consumable coupled to the imaging device 100. In another such example, the threshold temperature may be obtained from a computing device coupled to the imaging device 100. In some such examples, imaging device 100 may passively obtain (e.g., receive) or actively obtain (e.g., acquire) the threshold temperature.

In instruction 128, the start-up routine of the imaging device 100 may be suspended if the internal temperature 105 is below a threshold. As used herein, a "pause" start-up routine of an imaging device is a pause or stop of the start-up routine at any point prior to a step or operation of clearing printed material from the imaging device. In an example, removing the printing material may be removing a fluid, such as ink or a transport fluid, in the printing device. In such an example, the purged fluid may be a transport fluid disposed in a fluid ejection device of the imaging device 100, and the start-up routine may be invoked in response to first powering the imaging device 100. In another such example, the purged fluid may be ink disposed in a fluid ejection device of the imaging device 100, and the start-up routine may be invoked in response to an event, such as a change in power state. In such an example, the start-up routine may include the steps of purging the transport fluid from the fluid ejection device and replacing it with ink from a consumable coupled to the imaging device 100. In such an example, the instructions 128 may halt the startup routine prior to the clearing step or operation if the internal temperature 105 is less than the threshold temperature.

In instructions 130, an external temperature 107 of the imaging device 100 may be obtained. In an example, the external temperature 107 of the imaging device 100 may be a temperature outside of a chassis of the imaging device. In some examples, the external temperature 107 may be obtained from a temperature sensor disposed on an outer surface of the chassis of the imaging device 100. In other examples, the external temperature 107 may be obtained from a temperature sensor inside the chassis of the imaging device 100. In one such example, the external temperature sensor may be disposed on an inner surface of a chassis of the imaging device 100. In an example, the external temperature sensor may be an ambient air temperature sensor of the imaging device 100. In some examples, the external temperature 107 may be obtained from a temperature sensor that obtains the internal temperature 105 in operation 126.

In instruction 132, if the external temperature 107 is greater than the internal temperature 105, a fan of the imaging device 100 may be started, powered on, or energized. In such an example, the fan may circulate warmer outside air into the chassis of the image forming apparatus 100 and may thus increase the internal temperature of the image forming apparatus 100. In other words, in an example, the fan may exchange the internal air of the image forming apparatus 100 with the external air, and may thus increase the internal temperature of the image forming apparatus 100. In an example, the fan of the image forming apparatus 100 may be any fan of the image forming apparatus 100. In one example, the fan of the image forming apparatus 100 may be a fan of a dryer of the image forming apparatus 100. In another example, the fan may be an aerosol fan of the imaging device 100.

In optional instructions 134, the heating elements of the imaging device 100 may be activated, powered on, or energized when the external temperature 107 is below a threshold temperature. In such an example, the threshold temperature may be the same threshold temperature described above with respect to instructions 126. In other examples, the threshold temperature may be a different threshold temperature than the threshold temperature of the instructions 126. In such an example, the threshold temperature may be a particular temperature stored in the imaging apparatus 100. In other examples, the threshold temperature may be variable depending on various characteristics of the imaging device and any consumables coupled thereto. For example, the threshold temperature may be determined according to a characteristic of a consumable coupled thereto. In such examples, the threshold temperature may be determined according to the type of consumable coupled to imaging device 100 (e.g., a cartridge or toner cartridge) and the size (e.g., the volume of toner or ink contained in the cartridge). In some such examples, the threshold temperature may be determined by imaging device 100. In other such examples, the threshold temperature may be obtained by the imaging device 100. For example, the threshold temperature may be obtained from a consumable coupled to the imaging device 100. In another such example, the threshold temperature may be obtained from a computing device (e.g., a computer, mobile phone, tablet computer, server, etc.) coupled to the imaging device 100. In some such examples, imaging device 100 may passively obtain (e.g., receive) or actively obtain (e.g., acquire) the threshold temperature.

in an example, the heating element may be any heating element of the imaging device 100. In an example, the heating element may be a heating element of a fluid or powder handling system. In other examples, the heating element may be a space heating element inside the chassis of the imaging device 100. In one example, the heating element may be a heating element of a dryer of the image forming apparatus 100. In other examples, the heating element may be a heating element of a warming tray of the image forming apparatus 100. In such an example, the warming tray of the image forming apparatus 100 may be a tray that contains a printing material such as a medium (e.g., paper).

In an example, the fan and/or heating element may be turned off when the internal temperature of the imaging device increases by a particular amount. In an example, the particular amount may be in a range of five to fifteen degrees Celsius (5-15℃.). In other examples, the fan and/or heating element may be turned off when the internal temperature rises above a threshold temperature. In some examples, the threshold temperature may be the same temperature as described with respect to instructions 126 or 128. In other examples, the threshold temperature may be a different threshold temperature than described with respect to instructions 126 and 128. In such an example, the threshold temperature may be determined according to a characteristic of a consumable coupled thereto. In such examples, the threshold temperature may be determined according to the type of consumable coupled to imaging device 100 (e.g., a cartridge or toner cartridge) and the size (e.g., the volume of toner or ink contained in the cartridge). In some such examples, the threshold temperature may be determined by imaging device 100. In other such examples, the threshold temperature may be obtained by the imaging device 100. For example, the threshold temperature may be obtained from a consumable coupled to the imaging device 100. In another such example, the threshold temperature may be obtained from a computing device coupled to the imaging device 100. In some such examples, imaging device 100 may passively obtain (e.g., receive) or actively obtain (e.g., acquire) the threshold temperature.

In some examples, instructions 122, 124, 126, 128, 130, 132, and 134 may be part of an installation package that, when installed, is executable by processing resource 110 to implement the functionality described herein with respect to instructions 122, 124, 126, 128, 130, 132, and 134. In such examples, the storage medium 120 may be a portable medium, such as a CD, DVD, flash drive, or memory maintained by the imaging device from which the installation package may be downloaded and installed. In other examples, instructions 122, 124, 126, 128, 130, 132, and 134 may be part of an application, multiple applications, or component already installed on imaging device 100 that includes processing resource 110. In such examples, storage medium 120 may include a memory, such as a hard disk drive, a solid state drive, or the like. In some examples, the functionality described herein with respect to fig. 1 may be provided in conjunction with the functionality described herein with respect to any of fig. 2-4C.

FIG. 2 is a block diagram of an example system 210 that changes the temperature of an imaging device 200. In some examples, the system 210 may be disposed in the imaging device 200. In the example of fig. 2, the system 210 includes at least engines 212, 214, 216, and 218, which may be any combination of hardware and programming to implement the functionality of the engines. In the examples described herein, such a 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 the engines 212, 214, 216, and 218. In such examples, system 210 may include a machine-readable storage medium storing the instructions and a processing resource executing the instructions, or the machine-readable storage medium may be separate but accessible to system 210 and the processing resource.

In some examples, the instructions may be part of an installation package that, when installed, is executable by the processing resource to implement at least the engines 212, 214, 216, and 218. In such examples, the machine-readable storage medium may be a portable medium, such as a CD, DVD, flash drive, or memory maintained by the imaging device from which the installation package may be downloaded and installed. In other examples, the instructions may be part of an application, multiple applications, or component that has been installed on the system 210 that includes the processing resources. 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 system 210 may be implemented in the form of electronic circuitry.

In the example of fig. 2, consumable detection engine 212 may determine whether consumable 270 is coupled to imaging device 200. Consumable 270 may be any consumable as described above with respect to fig. 1. In an example, consumable detection engine 212 can be coupled to any type of electrical or mechanical switch and/or interface to indicate the presence of consumable 270. In one such example, consumable detection engine 212 can obtain an electrical signal to indicate that a consumable is coupled to imaging device 200.

In an example, the temperature detection engine 214 may obtain an internal temperature 205 of a housing or chassis of the imaging device 200. For example, the temperature detection engine 214 may obtain the internal temperature 205 from the temperature sensor 220. In such an example, the temperature detection engine 214 may determine whether the internal temperature is less than a first threshold. As described above with respect to fig. 1, the temperature sensor 220 may be any temperature sensor of the imaging device 200. In some examples, the temperature detection engine 214 may obtain the external temperature 207 of the imaging device 200. In one such example, the temperature detection engine 214 may obtain the external temperature 207 from the temperature sensor 225. In such an example, the temperature sensor 225 may be any temperature sensor for detecting an external or ambient temperature, as described above with respect to fig. 1. In an example, the temperature sensor 225 may be disposed on an inner or outer surface of the chassis of the imaging device 200. Although shown as separate temperature sensors, temperature sensor 220 and temperature sensor 225 may be the same sensor. In other examples, the temperature detection engine 214 may obtain the external temperature 207 from another device coupled thereto. For example, the temperature detection engine 214 can obtain the external temperature 207 from a device coupled thereto via a direct electrical connection or an indirect electrical connection.

In an example, the start-up suspend engine 216 may suspend the start-up routine of the imaging apparatus 200 if the internal temperature 205 is less than a threshold temperature. As described above with respect to fig. 1, the start-up routine may be suspended prior to reaching a step or operation to clear printed material from the imaging device 200. In some examples, the start-up pause engine 216 may determine whether a start-up routine is to be initiated in the imaging apparatus 200.

In an example, if the internal temperature 205 is less than the threshold temperature, the temperature control engine 218 may activate at least one of the fan 230 and the heating element 240. As described above with respect to fig. 1, the fan 230 and the heating element 240 may warm the interior of the housing or chassis of the imaging device 200. In such examples, the system 210 may change the temperature of the imaging device 200. In some examples, as described above, the fan 230 may be a fan of a dryer of the image forming apparatus 200. In some examples, as described above, the heating element 240 may be a heating element of a dryer of the image forming apparatus 200. In such an example, the imaging device 200 may be an inkjet printing system having a fluid ejection device. In one such example, the fluid ejection devices of imaging device 200 may include an array of fluid ejection dies (a page-wide array of fluid ejection dies) arranged across the width of the media in the direction of travel of the media through imaging device 200. In another such example, the fluid ejection device of imaging device 200 may reciprocate across the width of the media along the direction of travel of the media through imaging device 200.

FIG. 3 is a flow chart of an example method 300 for heating an imaging device. Although execution of method 300 is described below with respect to system 210 of fig. 2 described above, other suitable systems for executing method 300 may be utilized (e.g., imaging device 100). Further, implementation of method 300 is not limited to such examples.

At 302 of method 300, the temperature detection engine 214 may determine an internal temperature of the imaging device 200.

At 304, the start-up pause engine 216 may determine whether a start-up routine is to be initiated in the imaging apparatus 200.

At 306, the start-up pause engine 216 may pause the start-up routine if the internal temperature is below the first threshold.

at 308, when the internal temperature is below a first threshold, the temperature control engine 218 may cause at least one of the fan 230 and the heating element 240 of the imaging device 200 to start, power up, or energize.

Although the flow diagram of fig. 3 shows a particular order of execution of certain functions, the method 300 is not limited to that order. For example, functions illustrated in succession in the flowchart may be executed in a different order, concurrently or with partial concurrence, or combinations thereof. In some examples, the functionality described herein with respect to fig. 3 may be provided in combination with the functionality described herein with respect to any of fig. 1-2 and 4A-4C.

Fig. 4A-4C are flowcharts of an example method 400 for heating an imaging device that may be incorporated into the flowchart of fig. 3. Although execution of the method of fig. 4A-4C is described below with respect to system 210 of fig. 2 and the flowchart of fig. 3 described above, other suitable systems (e.g., imaging device 100) for executing the method of fig. 4A-4C may be utilized. Furthermore, the implementation of the method of fig. 4A-4C is not limited to such an example.

At 402 of fig. 4A, the temperature detection engine 214 may determine an external temperature of the imaging device 200. In some examples, the temperature detection engine 214 may obtain the external temperature 207 from the temperature sensor 225. In other examples, the temperature detection engine 214 may obtain the external temperature 207 from another device coupled thereto, e.g., via an indirect electrical connection. In one example, the fan 230 may circulate outside air into the image forming apparatus when the outside temperature 207 is greater than the inside temperature 205. In this manner, as described above with respect to fig. 1 and 2, the fan 230 may increase the temperature of the image forming apparatus when warmer outside air is introduced into the chassis of the image forming apparatus 200.

At 404 of fig. 4B, when the internal temperature 205 increases by a particular amount, the temperature control engine 218 may turn off the fan 230 and/or the heating element 240. In one example, the particular amount may be in a range of five to fifteen degrees Celsius (5-15℃.).

at 406 of fig. 4C, the temperature control engine 216 may turn off the fan 230 and/or the heating element 240 when the internal temperature 205 is above a threshold temperature. In some examples, the threshold temperature may be the same temperature as described with respect to 306. In other examples, the threshold temperature may be a different threshold temperature than described with respect to 306.

Although the flow diagrams of fig. 4A-4C illustrate a particular order of execution of certain functions, the flow diagrams of fig. 4A-4C are not limited to that order.
