Background

Imaging systems, such as printers, may allow text, images, and/or graphics, etc. to be printed onto a print medium (e.g., paper, plastic, etc.). Imaging systems typically include a print cartridge to facilitate transfer of print material to a print medium. The transfer of the printing substance to the print medium may produce text, images, and/or graphics, etc. on the print medium.

Detailed Description

Print cartridges may be included in a printing device to produce text, images, graphics, and/or the like on a print medium. The print cartridge may include a coupling member, a roller mechanism, and an urging member. The roller mechanism may be connected to the reservoir housing. The coupling part may be connected to a drive mechanism. The drive mechanism may connect the coupling member to the printing apparatus. Print cartridges help printing devices produce text, images, and/or graphics on print media by helping to transfer printed material onto the print media. However, if the print cartridge fails, it may be difficult for the user to determine why the print cartridge failed and/or to repair the print cartridge. In addition, the production cost of the print cartridge can be expensive.

Thus, the present disclosure describes roller and link shifting that allows the link components and roller mechanisms to be connected to the printing apparatus in a manner that reduces the cost of producing the print cartridge, makes it easier for a user to determine why the print cartridge has failed, and makes it easier for the user to repair the print cartridge. For example, the print cartridge may include a coupling member coupled to the roller mechanism. The position of the coupling member relative to the roller mechanism does not change with movement of the coupling member and roller mechanism. In some examples, the urging member may be positioned away from the coupling member to displace the roller mechanism and the coupling member from the second position to the first position.

FIG. 1 illustrates example systems 100-1 and 100-2 consistent with the present disclosure. Systems 100-1 and 100-2 may be implemented in various imaging systems, such as printers, copiers, and so forth. The system 100-1 of FIG. 1 illustrates an example system in a first location, and the system 100-2 of FIG. 1 illustrates an example system in a second location. In some examples, systems 100-1 and 100-2 may include coupling components 102-1 and 102-2. Coupling parts 102-1 and 102-2 may be connected to printing devices 103-1 and 103-2. In some examples, coupling members 102-1 and 102-2 may be displaced in a lateral direction when connected to printing devices 103-1 and 103-2. For example, when connected to printing devices 103-1 and 103-2, coupling components 102-1 and 102-2 may be displaced in the direction indicated by arrow 155. In some examples, coupling components 102-1 and 102-2 may be moved and/or displaced relative to printing devices 103-1 and 103-2. For example, coupling components 102-1 and 102-2 may move and/or shift while printing devices 103-1 and 103-2 remain in a stationary position. In some examples, coupling components 102-1 and 102-2 connected to printing devices 103-1 and 103-2 may assist in transferring printing substance onto a print medium. It will be understood that when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may be present.

In some examples, coupling components 102-1 and 102-2 connected to printing devices 103-1 and 103-2 may have a uniform diameter. For example, the diameter of coupling members 102-1 and 102-2 may be the same throughout coupling members 102-1 and 102-2. In some examples, the interior of coupling members 102-1 and 102-2 may be hollow. That is, an opening may be formed in the center of coupling members 102-1 and 102-2 to create a hollow center of coupling members 102-1 and 102-2. However, the present disclosure is not limited thereto. In some examples, coupling components 102-1 and 102-2 may be solid components that are not hollow inside. For example, coupling components 102-1 and 102-2 may be solid objects with no gap or space therebetween. In some examples, hollow coupling members 100-1 and 100-2 may reduce the cost of manufacturing coupling members 102-1 and 102-2. In some examples, coupling members 102-1 and 102-2 may be displaced with roller mechanisms 104-1 and 104-2.

That is, coupling members 102-1 and 102-2 may be coupled to roller mechanisms 104-1 and 104-2. As used herein, a "roller mechanism" refers to a device that transfers printing substance directly or indirectly from a supply of printing substance to a print medium. The systems 100-1 and 100-2 may utilize a variety of different roller mechanisms 104-1 and 104-2. For example, roller mechanisms 104-1 and 104-2 may be organic photoconductors. In addition, the roller mechanisms 104-1 and 104-2 may be developing rollers. Coupling members 102-1 and 102-2 may be rigidly connected to roller mechanisms 104-1 and 104-2. For example, coupling members 102-1 and 102-2 and roller mechanisms 104-1 and 104-2 may be coupled in a manner that allows coupling members 102-1 and 102-2 and roller mechanisms 104-1 and 104-2 to move and/or displace together. In some examples. Roller mechanisms 104-1 and 104-2 and coupling members 102-1 and 102-2 may be displaced together in the direction indicated by arrow 155. That is, roller mechanisms 104-1 and 104-2 and coupling members 102-1 and 102-2 may be displaced and/or moved together in a lateral direction.

In some examples, the position of coupling members 102-1 and 102-2 relative to roller mechanisms 104-1 and 104-2 may remain the same as coupling members 102-1 and 102-2 and roller mechanisms 104-1 and 104-2 are displaced between first position 100-1 and second position 100-2. For example, as coupling members 102-1 and 102-2 and roller mechanisms 104-1 and 104-2 are displaced together between positions, coupling members 102-1 and 102-2 may move the same distance 116-1 as roller mechanisms 104-1 and 104-2. That is, the position of roller mechanisms 104-1 and 104-2 relative to coupling members 102-1 and 102-2 is constant and unchanging.

In some examples, the systems 100-1 and 100-2 may include pushing members 106-1 and 106-2 to displace the roller mechanisms 104-1 and 104-2. In some examples, pushing members 106-1 and 106-2 may be coupled to roller mechanisms 104-1 and 104-2. However, the present disclosure is not limited thereto. For example, pushing members 106-1 and 106-2 may contact roller mechanisms 104-1 and 104-2. In some examples, the pushing member 106-2 may apply a force to displace the roller mechanism 104-2 while in contact with the roller mechanism 104-2. In some examples, the pushing members 106-1 and 106-2 may not contact the roller mechanisms 104-1 and 104-2. For example, the pushing member 106-2 may apply a force to the roller mechanism 104-2 using an object between the pushing member 106-2 and the roller mechanism 104-2. That is, when a force is applied from the pushing member 106-2 to the roller mechanism 104-2, the pushing member 106-2 may not be in direct contact with the roller mechanism 104-2. As used herein, "urging member" refers to a device for applying a force to a roller mechanism by direct or indirect contact and displacing and/or moving the roller mechanism due to the force applied by the device.

In some examples, pushing member 106-2 may displace roller mechanism 104-2 and coupling member 102-2 from second position 100-2 to first position 100-1. As used herein, "second position" refers to a position where the roller mechanism presses the pushing member and/or the roller mechanism is pushed toward the pushing member. The system 100-2 of fig. 1 illustrates the roller mechanism 104-2 in a second position. For example, when in the second position 100-2, the roller mechanism 104-2 may exert a force on the pushing member 106-2. The force exerted by the roller mechanism 104-2 on the pushing member 106-2 may compress the pushing member 106-2. As used herein, "first position" refers to a position where the roller mechanism is pushed away from the urging member. The system 100-1 of FIG. 1 illustrates the roller mechanism 104-1 in a first position. For example, the roller mechanism 104-1 may be positioned away from the pushing member 106-1 such that the roller mechanism 104-1 does not apply a force to the pushing member 106-1 when in the first position 100-1. That is, when in the first position, the roller mechanism 104-1 does not press the pushing member 106-1.

In some examples, the pushing members 106-1 and 106-2 may be springs. However, the present disclosure is not limited thereto. That is, the urging member may be a device capable of applying a force and displacing the roller mechanism from the second position 100-2 to the first position 100-1. For example, the pushing members 106-1 and 106-2 may be wedge-shaped mechanisms, elastomers, etc., that may directly or indirectly exert a force on and/or push the roller mechanism 104-2 from the second position 100-2 to the first position 100-1.

In some examples, coupling member 102-2 may be subject to the same force and displacement as roller mechanism 104-2 when pushing member 106-2 applies a force to roller mechanism 104-2. That is, the pushing member may displace and/or move both roller mechanism 104-2 and coupling member 102-2 in the same direction. In some examples, pushing members 106-1 and 106-2 may connect coupling members 102-1 and 102-2 to printing devices 103-1 and 103-2 when a force is exerted on roller mechanism 104-2 and coupling members 102-2.

Fig. 2 illustrates an example of an apparatus 220 consistent with the present disclosure. In some examples, apparatus 220 may include coupling member 202. In some examples, coupling component 202 may be connected to a printing device. In some examples, coupling member 202 may be connected to a printing apparatus by a drive mechanism 208. In some examples, the drive mechanism 208 may displace and/or move the coupling member 202 in a lateral direction. For example, the drive mechanism 208 may displace the coupling member 202 from side to side. In some examples, coupling component 202 may be displaced and/or positionally adjusted while the printing apparatus remains stationary. In some examples, a coupling component 202 connected to the drive mechanism 208 may assist in transferring the print material to the print media.

In some examples, drive mechanism 208 may be adjacent coupling member 202 and displace and/or reposition coupling member 202. That is, the drive mechanism 208 may displace the coupling member 202 from the first position to the second position. For example, the drive mechanism 208 may apply a force to the coupling member 202 that displaces the coupling member 202 from the first position to the second position. It will be understood that when an element is referred to as being "adjacent" to another element, it can be on, in contact with, connected to, near, or coupled to the other element.

In some examples, coupling member 202 may be coupled to roller mechanism 204. The coupling member 202 may be rigidly connected to the roller mechanism 204. For example, the position of the roller mechanism 204 relative to the coupling member 202 may be constant. In some examples, roller mechanism 204 may displace and/or change position as coupling member 202 displaces and/or changes position. For example, coupling member 202 and roller mechanism 204 may be coupled together such that coupling member 202 and roller mechanism 204 move and/or displace together. In some examples, roller mechanism 204 and coupling member 202 may be displaced together in a lateral direction.

In some examples, drive mechanism 208 may displace roller mechanism 204 and coupling member 202 from a first position to a second position. For example, when the drive mechanism 208 applies a force to the coupling member 202, the same force may be applied to the roller mechanism 204 to displace and/or change position the roller mechanism. In some examples, the arrangement of the roller mechanism 204 relative to the coupling member 202 is constant and unchanging. For example, when coupling member 202 and roller mechanism 204 are displaced together between positions, coupling member 202 may move the same distance as roller mechanism 204. That is, the position of coupling member 202 relative to roller mechanism 204 may remain the same as the coupling member and roller mechanism are displaced between the first and second positions. In some examples, the roller mechanism 204 may be displaced toward the pushing member 206 when the drive mechanism 208 exerts a force on the coupling member 202.

For example, the drive mechanism 208 may displace the coupling member 202 and the roller mechanism 204 a distance. That is, coupling member 202 and roller mechanism 204 are movable a distance to shift from a first position to a second position. In some examples, the drive mechanism 208 may displace the coupling member 202 and the roller mechanism 204 a distance in a range of about 1.0 millimeters (mm) to about 15.0 millimeters (mm). For example, in some examples, drive mechanism 208 may displace coupling member 202 and roller mechanism 204 a distance within the following range: from about 1.0 mm to about 15.0 mm, from 2.54 mm to about 15.0 mm, from 3.54 mm to about 15.0 mm, from 3.81 mm to about 15.0 mm, from 5.35 mm to about 15.0 mm, from 6.35 mm to about 15.0 mm, from 8.89 mm to about 15.0 mm, from 11.43 mm to about 15.0 mm, from 13.97 mm to about 15.0 mm, from 1.0 mm to about 14.5 mm, from 1.0 mm to about 12.7 mm, from 1.0 mm to about 10.16 mm, from 1.0 mm to about 7.62 mm, from 1.0 mm to about 5.08 mm, from 1.00 mm to about 4.08 mm, from 1.0 mm to about 3.04 mm, from 1.0 mm to about 2.54 mm, and from 1.0 mm to about 2.0 mm.

In some examples, the drive mechanism 208 may cause the roller mechanism 204 to exert a force on the push member 206. For example, the drive mechanism 208 may displace the coupling member 202 and the roller mechanism 204 in unison from the first position to the second position and exert a force on the pushing member 208. In some examples, the pushing member 206 may exert a force on the roller mechanism 204 in response to the roller mechanism 204 exerting a force on the pushing member 206. That is, the pushing member 206 may displace the roller mechanism 204 and the coupling member 202 in unison away from the pushing member 206 to the first position.

For example, the pushing member 206 may displace the roller mechanism 204 and the coupling member 202 a distance in a range from 1.0 millimeters to about 15.0 millimeters. For example, in some examples, pushing member 206 may displace roller mechanism 204 and coupling member 202 a distance within the following range: from about 1.0 mm to about 15.0 mm, from 2.54 mm to about 15.0 mm, from 3.54 mm to about 15.0 mm, from 3.81 mm to about 15.0 mm, from 5.35 mm to about 15.0 mm, from 6.35 mm to about 15.0 mm, from 8.89 mm to about 15.0 mm, from 11.43 mm to about 15.0 mm, from 13.97 mm to about 15.0 mm, from 1.0 mm to about 14.5 mm, from 1.0 mm to about 12.7 mm, from 1.0 mm to about 10.16 mm, from 1.0 mm to about 7.62 mm, from 1.0 mm to about 5.08 mm, from 1.00 mm to about 4.08 mm, from 1.0 mm to about 3.04 mm, from 1.0 mm to about 2.54 mm, and from 1.0 mm to about 2.0 mm.

In some examples, apparatus 220 may include a non-transitory machine-readable medium 210 storing instructions executable by a processing resource (e.g., processing resource 441 of fig. 4). In some examples, the medium 210 may include instructions executable by a processing resource to displace a drive mechanism 208 coupled to the coupling member 202. In some examples, drive mechanism 208 may displace coupling member 202 and roller mechanism 204 from a first position to a second position. That is, when a drive mechanism 208 connected to coupling member 202 displaces coupling member 202 from a first position to a second position, roller mechanism 204 may displace with coupling member 202 as roller mechanism 204 is coupled to coupling member 202.

In some examples, the medium 210 may include instructions executable by the processing resource to displace the drive mechanism by a distance in a range from about 1.0 millimeter to about 15.0 millimeters. That is, the drive mechanism 208 may displace the coupling member 202 and the roller mechanism 204 from the first position to the second position. In some examples, coupling member 202 and roller mechanism 204 are movable a distance to displace from a first position to a second position. For example, the drive mechanism 208 may displace the coupling member 202 and the roller mechanism 204 a distance in the range of about 2.54 millimeters to about 3.8 millimeters.

Fig. 3 illustrates an example of a print cartridge 330 consistent with the present disclosure. The print cartridge 330 may include a coupling member 302. In some examples, the coupling component 302 may be connected to a printing apparatus by a drive mechanism. In some examples, the drive mechanism may displace the coupling member to the second position. In some examples, the coupling member 302 may have a first diameter and a second diameter. That is, the coupling component may be configured in a manner that allows the coupling component 302 to have two different diameters.

For example, the diameter of the coupling member 302 may not be the same throughout the coupling member 302. In some examples, the first diameter of the coupling member 302 may be less than the second diameter of the coupling member 302. In some examples, the first diameter of coupling member 302 may be located at an end of the coupling member. As used herein, "distal" refers to an end that is within 25% of the outermost area of an object.

In some examples, the second diameter of the coupling member 302 may be located in the middle of the coupling member 302. That is, the middle of the coupling member 302 may have a diameter that is different and distinct from the diameter of the end of the coupling member 302. As used herein, "medial" refers to a point or portion that is equidistant from all sides and or ends.

In some examples, the coupling member is coupled to the receptacle housing 314. The container housing 314 may contain a printing substance. In some examples, coupling member 302 coupled to container housing 314 may assist in transferring print material to print media. In some examples, the reservoir housing may be coupled to the roller mechanism 304. That is, the roller mechanism 304 may be coupled to the reservoir housing 314 on a second side of the roller mechanism 304. Additionally, the roller mechanism 304 may be coupled to the coupling member 302 on a first side of the roller mechanism 304.

For example, roller mechanism 304 is coupled to coupling member 302 in a manner that allows coupling member 302 and roller mechanism 304 to move and/or displace together. That is, the coupling member 302 may be securely coupled such that the coupling member 302 changes position in unison with the roller mechanism 304. In some examples, the roller mechanism 304 and the coupling member 302 may be displaced and/or moved in a lateral direction. That is, displacing the coupling member 302 and roller mechanism 304 in unison may mate the print cartridge 330 with the printing apparatus. For example, when the coupling member 302 and the roller mechanism 304 are displaced, the coupling member 302 may be connected to the printing apparatus by the driving mechanism.

In some examples, the position between the coupling member 302 and the roller mechanism 304 does not change. That is, when the coupling member 302 and the roller mechanism 304 change positions, the position of the roller mechanism 304 relative to the coupling member 302 is constant and does not change. For example, when the drive mechanism and/or the pushing member moves the roller mechanism 304 and the coupling member 302, the coupling member 302 may move the same distance as the roller mechanism 304.

In some examples, the roller mechanism 304 may be mounted to the protective housing 312. In some examples, the protective housing 312 may protect the roller mechanism 304 from nearby objects when the roller mechanism 304 is displaced. In some examples, the protective housing 312 may reduce the amount of friction experienced by the roller mechanism 304 from other objects when the roller mechanism 304 is displaced. In some examples, the roller mechanism 304 may be connected to the pushing member 306 on a second side of the roller mechanism 304. That is, the pushing member 306 may not be in direct contact with the coupling member 302. In some examples, the pushing member 306 may be positioned between the roller mechanism 304 and the reservoir housing 314. In some examples, the receptacle housing 314 may secure the pushing member 306 in place when the pushing member 306 exerts a force on the roller mechanism 304 and displaces the roller mechanism 304 and the coupling member 302 to the first position. In some examples, positioning the pushing member 306 away from the coupling member 302 may allow a user to easily identify a problem with the print cartridge 330. In addition, positioning the pushing member 306 on the second side of the roller mechanism 304, away from the coupling member 302, may provide more space during assembly and/or may allow for easy servicing of the print cartridge 330.

Fig. 4 illustrates example processing resources 441 and example memory resources 442 of an example apparatus 440 consistent with the present disclosure. As shown in FIG. 4, device 440 includes processing resources 441 and memory resources 442. The processing resource 441 may be a hardware processing element such as a microprocessor, a special-purpose instruction set processor, a coprocessor, a network processor, or similar hardware circuitry that may cause machine-readable instructions to be executed. In some examples, processing resources 441 may be a plurality of hardware processing units that may cause machine-readable instructions to be executed. The processing resources 441 may include a Central Processing Unit (CPU) as well as other types of processing units. The memory resources 442 may be any type of volatile or non-volatile memory or storage, such as Random Access Memory (RAM), flash memory, Read Only Memory (ROM), storage volumes, hard disks, or a combination thereof.

Memory resource 442 may store instructions thereon, such as instructions 443 and 444. The instructions, when executed by the processing resources 441, may cause the apparatus 440 to perform specific tasks and/or functions. For example, memory resource 442 may store instructions 443, which instructions 443 may be executed by processing resource 442 to cause device 440 to displace a drive mechanism coupled to an attachment component. In some examples, the drive mechanism may displace the coupling member and the roller mechanism from the first position to the second position. That is, when the drive mechanism connected to the coupling member moves the coupling member, the roller mechanism may be displaced with the coupling member because the roller mechanism is coupled to the coupling member.

Memory resource 442 may store instructions 444 that are executable by processing resource 441 to cause device 440 to displace a drive mechanism a distance in a range of about 1.0 millimeter to about 15.0 millimeters. That is, the drive mechanism may move the coupling member and the roller mechanism to the second position. For example, the drive mechanism may displace the coupling member and roller mechanism a distance in the range of about 2.54 millimeters to about 8.89 millimeters.
