International Classification:

B41J 1142

US Classification:

400582, 400624, 400626, 347104

Abstract:

A Z-fold print media handling system for printing banners and the like uses an inkjet printing mechanism without a tractor-feed. A series of stuttering stopping and starting steps generates varying static and dynamic frictional forces to separate the first sheet of a Z-fold stack from the remainder of the stack. Both conventional cut-sheet media and Z-fold media are fed using the same printing mechanism, which pulls the media toward a printzone through frictional engagement with a first surface of the media To prevent printhead crashes and smearing the image near the perforations joining the Z-fold sheets, the printhead to media spacing is increased for Z-fold media over the standard spacing used for cut-sheet media. A cam feature is incorporated into the media drive clutch disk to determine whether an operator has set a selector lever for cut-sheet or Z-fold printhead to media spacing.

US Classification:

347108, 347101

Abstract:

An imaging apparatus has an interior cavity therein. A carriage is disposed within the interior cavity and is movable through a length of travel within the interior cavity. A cartridge is carried by the carriage. A swept volume includes the profile of the carriage and cartridge extended along the length of the carriage rod a distance equal to the length of travel of the carriage. A media tray is at least partially disposed within the cavity.

Abstract:

A sheet media handling system is provided for use in a sheet processor (e. g. , a printer). Such system incorporates an input tray for storing one or more sheet media prior to input through the printer's input port with the input tray vertically stacked with the printer's output support structure or tray. The system also has a single sheet medium guide mechanism adjacent the printer's output support structure, where the medium guide mechanism routes a single medium to the input port when the single medium is inserted therein. The single sheet medium guide mechanism includes a skew-abatement substructure and a deflection mechanism. The skew-abatement substructure is designed to facilitate alignment of and routing of a single medium towards the input port by contacting a first edge of the single medium and an opposite second edge of the single medium. Such a deflection mechanism is designed to deflect a single medium toward and into the input port by contacting the upper surface of the single medium while also contacting the lower surface of the single medium. The invented system facilitates easy manual insertion and alignment of a single medium (e. g.
