A combination cartridge apparatus includes a housing, an inkjet pen and a media cartridge. The combination cartridge is configured to hold the inkjet pen and media cassette adjacent to each other external of a printer. The inkjet pen and media cassette are configured to separate when the cartridge is installed in a printer and to rejoin when the cartridge is withdrawn from the printer.

Combined ink and media cartridge

A cartridge apparatus includes a media cassette, face plate and a locking and unlocking mechanism. The locking and unlocking mechanism includes a lock bar, a first post and a second post, and is configured to lock and unlock a cartridge during insertion in a printer.

An inkjet consumable cartridge having an inkjet cartridge having nozzles. The inkjet consumable cartridge also has an inkjet cartridge holding device for holding the inkjet cartridge, a cap configured to interface with the inkjet cartridge, and a cap actuator that, when actuated, moves the cap from a position where the cap does not interface with the inkjet cartridge to a position where the cap interfaces with the inkjet cartridge sealingly covering the nozzles. Furthermore, the consumable cartridge is removable from a printer as a self-contained unit.

A media handling system for handling sheets of media. The system includes a pick roller having a circumferential media-contacting surface and arranged for rotation about a roller axis to contact and pick a sheet from an input source. A drive roller rotates about a drive roller axis, with a media path extending between the pick roller and the drive roller. A first guide structure is positioned along a first longitudinal edge of the media path and providing a first media guide surface. A second guide structure is positioned along a second longitudinal edge of the media path and provides a second media guide surface. The first and second guide surfaces are positioned to constrain the movement of a media sheet in the media path between the pick roller and the drive roller, thereby alleviating trailing edge print defects.

A modular duplex media handling system used in conjunction with a simplex media handling print recording apparatus, includes a drive roller having a simple gear linkage. The simple gear linkage provides a fixed rotational relationship between the drive roller and a feed roller of the simplex handling apparatus. A media guide pivots about the drive roller's axle between a first position into which it is biased, and a second position into which it is deflected by a media sheet. From the first position, a media sheet retracting from a print zone can enter the duplex media handling system. From the second position, a media sheet can move from the input tray around the feed roller into the print zone, or move out of the duplex media handling system back into the input tray to await refeeding for second side printing.

A media handling system includes a drive roller, an elongated pinch roller and a contoured support. The pinch roller extends across the print medium near the print zone to control the localized shape of the print medium. The support underlies the print medium in the print zone and includes first and second underlying pivotal inclines. The pinch rollers push the print medium onto the first pivotal incline adjacent to the drive roller. The second underlying incline is located downstream toward the print zone exit. As the print medium is fed through the print zone, a portion of the print medium within the print zone between the pivotal inclines is suspended exhibiting a reverse bowing. Beyond the second pivotal incline the print medium droops. The presence of the two underlying inclines more uniformly distributes the stress accompanying the bowing of the print medium within the print zone.

A print media alignment apparatus is disclosed. An embodiment includes a first member configured to apply a varying force to at least one print media sheet of a print media stack. This force varies from a minimum below a first print media stack height to a maximum at a second print media stack height. The alignment apparatus also includes a second member configured to apply a constant force to the print media stack irrespective of the stack height. Another embodiment includes a print media width adjuster configured to be moveable adjacent a print media stack having at least one sheet of print media, the print media stack defining a plane. The alignment apparatus also includes a wall on the width adjuster. The wall includes a wall first print media contact surface configured to slope at an angle with respect to the plane. The alignment apparatus further includes a member attached to the width adjuster, the member including a member print media contact surface configured to be perpendicular to the plane. A method of aligning print media for use in a printing device is also disclosed. The method includes the steps of applying a varying first force to at least one sheet of print media at and above a first print media stack height and applying a second constant force to the print media irrespective of the print media stack height. The varying first force and the constant second force facilitate uniform alignment of the print media.
