An electronic pen comprises a retractable cartridge, a retraction mechanism for extending and retracting the cartridge, a button for actuating the retraction mechanism, a sensing arrangement for sensing a configuration of the pen, and a processor cooperating with the sensing arrangement. The processor is adapted to configure a state of the pen in response to input signals from the sensing arrangement. The sensing arrangement comprises a button sensor coupled to the button, which senses actuation of the button and a cartridge sensor for sensing whether the cartridge is extended or retracted.

A method of assembling a capping mechanism of an inkjet printer, the method comprising the steps of: providing a support frame for at least one elongate shaft; positioning the shaft so as to be supported at its longitudinal first and second ends by the support frame; positioning a bearing of a fixing plate about the first end of the shaft, the bearing being configured to allow rotation of the shaft, the rotation providing transport of a capper out of, and into, a capping position on a pagewidth printhead; and slidably engaging the fixing plate with the support frame so as to fix the shaft thereto, wherein, during the sliding engagement, the elongate shaft pivots about the second end due to the configuration of the bearing.

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. An actuator 20 mounted to the chassis 2 to disengage the contact foot 32 from the friction surface such that the stack engaging structure 8 moves relative to the lock mechanism 12 to press the top-most sheet 40 against the top sheet engaging 6, then the actuator disengages the contact foot 32 such that it re-engages the friction surface 18 and then moves the lock mechanism relative to the chassis 2 such that the stack engaging structure 8 also retracts a predetermined distance from the top-most sheet engaging member 6.

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. A common shaft is mounted connecting the first gear and two second gears to the body so that each of the second gears mesh with the second gear assembly. A pin of two third gears is mounted to the body so that each of the third gears mesh with a respective one of the second gears of the first gear assembly.

A printer is provided having a support frame, a media cartridge removably engaged with the support frame, the media cartridge having a supply of sheet media, a driven roller arranged to be rotated so as to contact and pick-up sheet media from the media cartridge and deliver the picked sheet media to a sheet media transport mechanism of the printer, and a gear assembly for engaging driving power from a motor to the driven roller. The gear assembly has a first gear on a shaft of the driven roller and a second gear directly coupled with the first gear. The gear assembly is configured to decouple the second gear from the first gear to thereby disengage said driving power upon delivery of the picked sheet media to the sheet media transport mechanism.

A method is described for positioning an image sensor at a point of best focus for a lens. The lens has an optical axis and the image sensor is moved to a plurality of positions along the optical axis. The image sensor captures an image of a target image at each of the plurality of positions through the lens. A measure of blur in the image captured is derived at each of the plurality of positions from pixel data output from the image sensor. A relationship is derived between blur and position of the image sensor along the optical axis. The image sensor is then moved to a position on the optical axis that the relationship indicates as the point of best focus where the image sensor is fixedly secured relative to the lens.

A method of assembling a media transport arrangement of a printer is provided. The method includes positioning a roller so as to be supported at a first end by a support frame, positioning a ring bearing of a fixing plate about a second end of the roller, the fixing plate being separate from the support frame, and slidably engaging the fixing plate with the support frame so as to fix the fixing plate and the roller to the support frame. During the sliding engagement, the roller pivots about the first end due to the configuration of the ring bearing.
