DETAILED DESCRIPTION
[0011] Printheads may be used in printers to print images on substrates. Periodically, the printheads in the printers may need to be replaced. At times, however, accessing and/or removing the printheads may be difficult. For example, the respective printheads may be removably installed into a recessed compartment of the printer. The recessed area may cause limitations for a user to view the compartment to receive the printhead and/or the printhead. Accordingly,
accessibility to grab and remove the printheads that are inserted in the printers may be limited. Thus, the removal of printheads from the printers may be difficult and time consuming.
[0012] In examples, a printhead includes a printhead housing and a handle. The handle is movably coupled to the printhead housing. The handle rotatably moves with respect to the printhead housing between a folded position and a non-folded position. In the folded position, the handle extends along a respective housing surface of the printhead housing. In the non-folded position, the handle extends outward from the respective housing surface of the printhead housing. In the non-folded position, the handle is configured to be accessed by a user to removably move the printhead housing into and out of a printer. Thus, the difficulty and amount of time to remove printheads from printers may be reduced.
[0013] FIG. 1 is a block diagram illustrating a printhead according to an example. Referring to FIG. 1, in some examples, a printhead 100 includes a printhead housing 10 and a handle 11. The handle 11 is movably coupled to the printhead housing 10. The handle 11 rotatably moves with respect to the printhead housing 10 between a folded position 11a and a non-folded position 11b. In the folded position 11a, the handle 11 extends along a respective housing surface 10a of the printhead housing 10. For example, the housing surface 10a may be a top or bottom surface of the printhead housing 10.
[0014] In some examples, in the folded position 11a, the handle 11 may be substantially parallel to the respective housing surface 10a. In some examples, the handle 11 may not extend above the respective housing surface 10a. In the folded position 11a, the printhead 100 including the handle 11 may be positioned such that the printhead 100 may not be inadvertently removed from the printer. In the non-folded position 11b, the handle 11 extends outward from the respective housing surface 10a of the printhead housing 10. Also, in the folded position 10a, an area needed to contain the printhead 100 may be reduced. In the non-folded position 11b, the handle 11 is configured to be accessed by a user to removably move the printhead housing 10 into and out of a printer. The handle 11 may also provide tactile feedback to the user. In some examples, the handle 11 may be U- shaped.
[0015] FIG. 2 is a perspective view illustrating a printhead according to an example. The printhead 200 may include the printhead housing 10 and the handle 11 as previously discussed with respect to the printhead 100 of FIG. 1. Referring to FIG.2, in some examples, the printhead housing 10 may include a removable printhead cartridge. For example, the removable printhead cartridge may be an inkjet printhead such as a thermal Inkjet printhead, a piezoelectric inkjet printhead, and the like. The removable printhead cartridge may include a nozzle surface 20a on one end and the respective housing surface 10a on another end thereof.
[0016] Referring to FIG. 2, in some examples, the nozzle surface 20a may include a plurality of nozzles 22, for example, in which printing fluid may be ejected there through and out of the removable printhead cartridge. The printhead housing 10 may be inserted into and removed from a printer. In some examples, a plurality of printheads 200 may be inserted into and removed from a recessed compartment 47 of the printer, and the like. The printhead 200 may also include a resilient member 23. For example, the resilient member 23 may include a spring. In some examples, the printhead 200 may include a plurality of resilient members 23.
[0017] FIGS. 3A and 3B are perspective views illustrating a handle of a printhead in a folded position and a non-folded position, respectively, according to examples. Referring to FIG. 3A, in the folded position 11a, a folded angle αf formed by the handle 11 and the respective housing surface 10a of the printhead housing 10 may be about zero degrees as illustrated in FIG. 3A. In some examples, the handle 11 may be substantially parallel to the respective housing surface 10a. For example, the respective printhead surface 10a may be a top or bottom surface of the printhead housing 10. In some examples, the handle 11 may not extend above the respective housing surface 10a. In the folded position 11 a, the printhead 200 including the handle 11 may be positioned such that the printhead 200 may not be inadvertently removed from the printer.
[0018] Referring to FIG. 3B, in some examples, the resilient member 23 may provide a force to bias the handle 11 to the non-folded position 11b. For example, the non-folded position 11b includes the handle 11 extending outward from the respective housing surface 10a of the printhead housing 10 and forming a non-folded angle αn with the respective housing surface 10a as illustrated in FIG. 3B. Thus, in a non-folded position 11b, the handle 11 may be accessed by a user to remove the printhead 200 from the printer. Also, in a non-folded position 11b, the handle 11 may be accessed by a user to insert the printhead 200 into the printer. In some examples, the non-folded angle an may be in a range of 25 to 75 degrees.
[0019] FIG.4 is a schematic view illustrating the printhead of FIG. 2 inserted in a printer according to an example. Referring to FIG.4, a printer 401 may include a recessed compartment 47, a cover member 46, and a printhead 200 removably inserted into a recessed compartment 47 of the printer 401. In some examples, a plurality of printheads 200 may be removably inserted into the recessed compartment 47. The cover member 46 may rotatably move to cover and uncover the printhead 200 inserted into the recessed compartment 47. For example, the cover member 46 may push the handle 11 to the folded position 11a when covering the printhead 200. Thus, in the folded position 11a, the printhead 200 including the handle 11 may not be inadvertently removed from the printer 401. Also, in the folded position 11a, an area needed to contain the printhead 200 may be reduced.
[0020] Referring to FIG.4, in the non-folded position 11b, the handle 11 is configured to be accessed by a user to removably move the printhead housing 10 into and out of a printer. The handle 11 may also provide tactile feedback to the user. In some examples, the handle 11 may be U-shaped. Additionally, when the cover member 46 is moved away from and no longer covering the printhead 200, the handle 11 is automatically moved to the non-folded position 11b. In the non- folded position 11b, the handle 11 may be easily access by the user to remove the printhead 200 from the recessed compartment 47 of the printer 401.
[0021] FIG. 5 is a block diagram illustrating a printhead according to an example. FIGS.6A, 6B, and 6C are perspective views illustrating the printhead of FIG.5 in various positions according to examples. Referring to FIGS. 5-6C, in some examples, a printhead 500 includes a printhead housing 10 and a handle 11. The printhead housing 10 includes a removable printhead cartridge to be removably inserted into a printer by a user. The handle 11 is movably coupled to the printhead housing 10. The handle 11 rotatably moves with respect to the printhead housing 10 between a folded position 11a (FIG.6A), an intermediate position 21b (FIG. 6B), and an upright position 21a (FIG. 6C).
[0022] The folded position 11a corresponds to the handle 11 extending along a respective housing surface 10a of the printhead housing 10 as illustrated in FIG.6A. For example, a folded angle of formed by the handle 11 and the respective housing surface 10a of the printhead housing 10 in a folded position 11a is about zero degrees. In some examples, the second non-folded angle α2n is in a range of 25 to 75 degrees. The upright position 21a corresponds to the handle 11 extending outward from the respective housing surface 10a of the printhead housing 10 and forming a first non-folded angle α1n with the respective housing surface 10a as illustrated in FIG. 6C. For example, in response to a user grabbing the handle 11 , a weight of the printhead 500 may fully extend the handle 11 to a fully upright orientation and provide tactile feedback to the user. In some examples, the first non-folded angle α1n is about 90 degrees. The intermediate position 21b corresponds to the handle 11 extending outward from the respective housing surface 10a of the printhead housing 10 and forming a second non-folded angle α2n with the respective housing surface 10a less than the first non-folded angle α1n as illustrated in FIG. 6B. For example, the handle 11 may be biased at the second non-folded angle to allow sufficient access for a user to grab.
[0023] FIG. 7 is a schematic view of the printhead of FIG. 5 in a disassembled state according to an example. FIGS. 8A and 8B are schematic views illustrating a lift spring and a return spring, respectively, of the printhead of FIG. 5 according to examples. Referring to FIGS. 7-8B, in some examples, the printhead 500 also includes a lift spring 73 and a return spring 74. The lift spring 73 lifts the handle 11 from the folded position 11a (FIG. 6A) to the intermediate position 21b (FIG. 6B). The return spring 74 pushes the handle 11 from the upright position 21a (FIG.6C) to the intermediate position 21 b. The lift spring 73 and the return spring 74 provide a force to bias the handle 11 to the intermediate position 21b to be accessed by the user to remove the removable cartridge from the printer. The handle 11 and the printhead housing 10 may include protrusions 77a and 77b such as ribs, and holes 78 to engage portions of the lift spring 73 and the return spring 74.
[0024] Referring to FIGS.7 and 8A, in some examples, the lift spring 73 may include a first lift leg portion 83a, a second lift leg portion 83b, and a lift intermediate portion 83c. In the assembled state, the first lift leg portion 83a contacts the handle 11. The second lift leg portion 83b contacts the printer. The lift intermediate portion 83c contacts the handle 11 and is disposed between the first lift leg portion 83a and the second lift leg portion 83b. The lift spring 73 lifts the handle 11 from the folded position 11a to the intermediate position 21b. That is, absent an overriding force, the lift spring 73 automatically lifts the handle 11 from the folded position 11 a to the intermediate position 21 b. For example, the handle 11 may be raised from the folded position 11a to the unfolded position 11 b by the first lift leg portion 83a sliding in the second lift leg portion 83b such as a U-shaped slot. [0025] Referring to FIGS. 7 and 8B, in some examples, the return spring 74 may include a first return leg portion 84a, a second return leg portion 84b, and a return intermediate portion 84c. In the assembled state, the first return leg portion 84a contacts the handle 11. The second return leg portion 84b contacts a printer. The return intermediate portion 84c contacts the handle 11 and is disposed between the first return leg portion 84a and the second return leg portion 84b. The return spring 74 pushes the handle 11 from the upright position 21a to the intermediate position 21b. That is, absent an overriding force, the return spring automatically pushes the handle 11 from the upright position 21a to the intermediate position 21b.
