Abstract: An inkjet printer comprises an elongate shaft adapted to rotate so as to move a capper for capping a pagewidth printhead out of and into capping position; a motor for driving the elongate shaft; a support frame; and first and second fixing plates mounted to the support frame. The first and second fixing plates each include first and second bearings for supporting the shaft at first and second longitudinal ends of the shaft so as to allow rotation of the shaft. The first and second bearings are configured to allow pivotal movement of the elongate shaft about first and second longitudinal ends thereof. The second fixing plate includes a seat for receiving the motor therein.

Abstract: A mobile device is disclosed. The mobile device includes an inkjet printhead, a print media feed path for directing print media past the printhead in a feed direction during printing, and a capping mechanism including a capper moveable between a capping position in which the capper is urged into a capping relationship with the printhead, and an uncapped position in which the capper is displaced away from the printhead thereby exposing the printhead to print media in the print media feed path. The capper is moved between the capped and uncapped position by engagement with an edge of the print media as the print media moves through the feed path.

Abstract: A gear arrangement for a capper of an inkjet printer comprises a first gear assembly mounted to the printer so as to cooperate with a motor gear for driving rotation of the first gear assembly, the first gear assembly having a code feature; and a second gear assembly mounted to the printer so as to cooperate with the first gear assembly to be rotatable therewith, the second gear assembly, in use, cooperating with a capper for capping a printhead so that the rotation of the second gear assembly moves the capper out of and into its capping position. The code feature of the first gear assembly is arranged to cooperate with a holding feature of a mounting arrangement used to mount the second gear assembly to the printer, the code feature being configured so that the cooperation with the holding feature maintains the first gear assembly at a predetermined position during the mounting of the second gear assembly.

Abstract: The present invention relates to a printer for printing digital colour photographs. The printer includes a printhead cartridge housing an ink ejection printhead and an ink supply configured to supply ink to the printhead. A cradle unit defines a support bay in which the printhead cartridge can be fitted in a removable manner. The cradle unit houses a media transport mechanism which transports print media past the printhead. A media supply cartridge is configured to supply the media to the transport mechanism.

Abstract: An inkjet printer comprising: an elongate shaft arranged, in use, to rotate so as to move a capper for capping a pagewidth printhead out of and into its capping position; a support frame for supporting the shaft at the longitudinal first and second ends of the shaft so as to allow the rotation of the shaft; and fixing means for fixing the shaft to the support frame at the first end of the shaft, the fixing means comprising: a bearing into which the first end of the shaft is positioned for allowing the rotation of the shaft; and engagement means arranged to slidably engage with the support frame so as to fix the shaft thereto, the bearing being configured to allow pivotal movement of the elongate shaft about the second end of the shaft during the sliding engagement of engagement means and support frame.

Abstract: A mobile device including: (a) an inkjet printhead; (b) a print media feed path for directing print media past the printhead in a feed direction during printing; and (c) a capping mechanism including a capper moveable between: a capping position in which the capper is urged into a capping relationship with the printhead; and an uncapped position in which the printhead is able to print onto the print media, wherein in the uncapped position the capper is displaced away from the printhead; wherein the capper is moved between the capped and uncapped position by an edge of the print media as it moves through the feed path.

Abstract: Provided is a mobile telephone which includes an internal printhead, an ink cartridge and an optical sensing arrangement. The internal inkjet printhead arrangement is fed with print media via internal and external pathways defined by a body of the telephone. The ink cartridge supplies ink to the printhead. The optical sensing arrangement enables the telephone to decode tags of coded data printed on such media fed through the internal and external pathways. The sensing arrangement includes a beam splitter configured to deflect incoming light onto an image sensor of the telephone, a first infrared LED operatively directing light onto media present in the external pathway, and a filter and lens arrangement configured to receive and direct light reflected from the external media onto the beam splitter.

Abstract: A mobile device including: (a) an inkjet printhead; (b) a print media feed path for directing a print medium past the printhead in a feed direction during printing; (c) a capping mechanism including a capper moveable between: a capping position in which the capper is urged into a capping relationship with the printhead; and an uncapped position in which the printhead is able to print onto the print medium, wherein in the uncapped position the capper is displaced away from the printhead; (d) a force transfer mechanism connected to the capper and configured such that a force provided by an edge of the print medium as it moves relative to the feed path is transferred to the capper by the force transfer mechanism, thereby to at least commence movement of the capper from the capped position to the uncapped position prior to the print medium reaching the capper.

Abstract: A sheet feed mechanism for a device such as a printer, with a chassis 2 configured to support a stack of sheets 4. A top sheet engaging member 6 for engaging the top-most sheet 40 of the stack and moving it relative to the remainder of the stack 4. A stack engaging structure 8 for engaging the stack 4 and biasing its top sheet 40 against the top sheet engaging member 6. The stack engaging structure 8 having a friction surface 18 extending parallel to the stack engaging structure's direction of travel. A lock mechanism 12 mounted to the chassis 2 for limited relative movement thereto, the lock mechanism 12 having a biased contact foot 32 for engaging the friction surface 18 to secure the stack engaging structure 8 to the lock mechanism 12 for movement therewith.

Abstract: A printer including: at least one elongate roller arranged, in use, to rotate so as to transport print media within the printer; a support frame for supporting the roller at the longitudinal first and second ends of the roller so as to allow the rotation of the roller; and fixing means for fixing the roller to the support frame at the first end of the roller, the fixing means including: a bearing into which the first end of the roller is positioned for allowing the rotation of the roller; and engagement means arranged to slidably engage with the support frame so as to fix the roller thereto, the bearing being configured to allow pivotal movement of the elongate roller about the second end of the roller during the sliding engagement of the engagement means and support frame.

Abstract: A printhead assembly with a printhead integrated circuit (IC) and a shut off (138) valve that has a valve body (200) defining an ink inlet (202) for connection to an ink supply, an ink outlet (67) connected to the printhead IC. A moveable valve member (212) is biased into sealing engagement with the valve seat (216) to provide a fluid seal between the ink inlet and the ink outlet. An actuator (204) for unsealing the valve member from the valve seat upon energizing and re-sealing the valve member to the valve seat when de-energized. The valve protects the ink in the ink supply from contaminants that can migrate up the ink line during shut down periods. The valve member is constantly biased to a closed position and so seals the ink supply from the printhead IC as a default condition even in the event of a power failure. The bias is strong enough to provide the fluid seal so that the seal is not compromised when the pressure difference between the inlet and the outlet is small.
