Abstract: A hand-operated printer includes a body, a printhead mounted to the body, a target sight mounted to the body, and a display device mounted to the body. The display device is configured to display an image and a representation of the target sight in relation to the image, and wherein the relation between the representation of the target sight and the image that are displayed on the display device corresponds to a relationship between the target sight and a print position for the image.

Abstract: A docking station includes a housing operable to receive and releasably secure a handheld printer, and a freeing mechanism, where the freeing mechanism is operable to release the handheld printer from the housing. The docking station also includes a print head cap operable to receive a print head of the handheld printer when the handheld printer is secured in the housing, and a print head wiper, where the print head wiper is operable to wipe the print head of the handheld printer during the release of the handheld printer from the housing.

Abstract: A hand-held printer includes at least one print nozzle and a guide for maintaining the alignment of the at least one print nozzle relative to an object. The guide is operable to operable to maintain the position of the at least one print nozzle relative to the object while the hand-held printer is in motion relative to the object, which is stored in a memory of the hand-held printer. The hand-held printer is operable to print an image using the at least one print nozzle.

Abstract: Methods and apparatus for monitoring the print quality maintenance of hand-held printers and insuring the performance of periodic maintenance to maintain optimal print quality.

Abstract: Handheld printers and methods of printing receive a first portion of a material underneath at least one print nozzle. At least a second portion of the material is mounted on a spool. The rotation of the spool is detected using an optical sensor. At least one print nozzle is instructed to eject ink onto the first portion of the material based, at least in part, on the detection of the rotation of the spool using the optical sensor.

Abstract: An imaging apparatus includes a sheet separation surface positioned along the sheet feed path downstream from a media tray. A plurality of pivoting arms is mounted in the imaging apparatus. The pivoting arms are moveable between a first position and a second position. The pivoting arms are positioned and individually spaced along a width of the sheet feed path. Each of the pivoting arms has a media stack engaging surface. When the pivoting arms are in the first position, the media stack engaging surface is non-parallel to the sheet separation surface. When the plurality of pivoting arms is in the second position, the media stack engaging surface is parallel to the sheet separation surface.

Abstract: An imaging apparatus includes a printhead carrier configured for movement along an X-axis. The printhead carrier includes a carrier housing having a first bearing pocket and a second bearing pocket. The first bearing pocket and the second bearing pocket are spaced apart along the X-axis. A Z-axis passes through a central region of the carrier housing. The Z-axis is substantially perpendicular to the X-axis. A first bearing is configured to be received in the first bearing pocket. The first bearing includes a first curved outer surface having a curve that extends in a direction of the X-axis. The curved outer surface is received in the first bearing pocket to facilitate a rotation of the first bearing in relation to the Z-axis of the carrier housing. A second bearing is configured to be received in the second bearing pocket.

Abstract: An imaging apparatus includes a printhead carrier configured for mounting a printhead cartridge and a cam rotatably coupled to the printhead carrier, the cam having a cam surface positioned opposite the datum pad, the cam surface being positioned for direct contact with the datum pad. A rotation of the cam causes the cam surface to translate the printhead along the media feed direction.

Abstract: A print medium exit system in a printer includes a kicker device ejecting a sheet of print medium out of the printer. A clutch mechanism prevents actuation of the kicker device when the clutch mechanism is engaged by the sheet of print medium.

Abstract: A waste ink accumulation system in an ink jet printer includes a rotatable body having an ink-collecting surface and a plurality of projections extending from the ink-collecting surface. An actuating mechanism rotates the body.

Abstract: A receptacle for the color ink spitting of a printhead to maintain the print nozzles and better collect the ink and transfer the waste ink to a containment area utilizes a porous open cell foam spit surface to allow the waste ink and air to pass through while maintaining some surfaces for the transport and collection of waste ink. This open cell design of the foam allows the ink and air to pass through it without deflecting the vast majority of the ink volume. The foam is hydrophobic foam to prevent the foam from absorbing the ink. The foam is also made from an ether-based material to be compatible with the inks. Walls forming a chimney are added to the sides of the foam to help contain and direct the waste ink flow from the printhead to the waste ink accumulation area in the printer. The spit foam and chimney direct the waste ink directly onto a felt absorption pad located below the spit surface where the waste ink is absorbed and stored.
