    摘要: Described herein is a printer having a printhead which traverses laterally across a sheetlike print medium and which thereby defines a laterally-extending print zone across the print medium. A paper transport mechanism in the printer has drive rollers and associated pinch wheels to drive the print medium through the printer's print zone. The paper transport mechanism further includes an upper print media guide and a lower print medium guide. The two print medium guides are shaped at their transverse ends to bow the transverse edges of the print medium downwardly to reduce its tendency to buckle upwardly into the printhead. In order to fit the upper print medium guide into the limited available space above the drive rollers, it is made of a lower molded portion for paper contact and an upper backing portion for rigidity. A pinch finger extends toward the printer's print zone beyond the pinch wheels to establish a pinch point against the drive roller in near proximity to the print zone.

    摘要: 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., an envelope or postcard) into the input port of a printer without affecting the existing supply of sheet media in the input tray.

    摘要: An improved printer paper pullout apparatus is described. In its preferred embodiment, the pullout apparatus includes a grasping mechanism, a capture mechanism and a securing mechanism. The grasping mechanism facilitates concurrent paper tray and paper stack movement from a printer feed zone. The securing mechanism ensures proper paper gripping before the paper tray can be released and extended from the printer feed zone. In addition, the grasping mechanism is shaped and positioned on the paper tray for ease of operator grip when manually extending the paper tray from the printer feed zone.

    摘要: A printhead cartridge and carriage assembly (10) is provided comprising: a carriage (12); a snap-spring (62) for securing a printing cartridge (14) in postion on the carriage; and an interconnect strip (16) for supplying electrical signals to the cartridge, including a force loading spring pad (24) for urging a portion of the interconnect strip against a portion of the cartridge. The cartridge has top (32), bottom (34), sides (36, 38), front (40) and rear (42) surfaces and includes a printhead (44) on the bottom surface, an electrical contact strip (46) on the back surface connected to the printhead, referencing pads (56) on the side surface, and a lip (64) on the back surface for accepting the snap-spring. Referencing surface (60) are provided for receiving the referencing pads on the cartridge. The spring pad urges the interconnect strip against the electrical contact of the cartridge. The printhead cartridge/carriage assembly of the invention requires only one hand of the operator to both insert and lock the cartridge in position. Further, the cartridge/carriage assembly provides simultaneous alignment of the printhead in the X, Y, and Z directions. Finally, contact between the printhead and the interconnect strip is reliably made each time the cartridge is inserted and locked in position, thereby ensuring proper nozzle firing each time.

    摘要: A novel ink-jet printer (10) is provided. The print provides both paper supply tray (12) and paper collection tray (18) in the front (14) of the printer for ease of paper handling and reduced footprint. The paper collection tray is provided with a pair of opposed output rails (22) which support a sheet of paper (16c) during printing to permit ink on a sheet of paper (16b) previously printed to dry. A paper handling mechanism is provided which eliminates a sheet pickup motor and associated elements. The paper handling mechanism is configured to pick off a sheet of paper from a stack of input paper, bring it around paper drive rollers (24) onto a platen (26), where the printing operation, employing a printhead cartridge (32), occurs. The printer further includes a service station (230) for clearing clogged nozzles in the printhead (33) and removing bubbles therefrom, for covering the nozzles with a protective cap (266), and for wiping contaminants off the nozzles. Reference pads (200) are provided for aligning and securing the printing cartridge in a carriage (35). The carriage is associated with a carriage guide (27), to which the carriage and print medium are referenced. The resulting printer is easy to manufacture, has reduced complexity by eliminating components in the paper drive mechanism and is lower in cost.

    摘要: An active paper drop mechanism (20) for ink-jet printers is provided. The mechanism comprises a pair of opposed, movable rail members (22) associated with opposed walls (14) of a horizontal-disposed output collection tray (12) for receiving sheets (10) of printed media.In particular, each rail member is provided with return spring (26) that act to maintain the rails in a closed position. In that position, the rails support a sheet of the print medium during the printing operation, thus giving the ink on the previously printed-on sheet (10') time to dry.The rails are provided with a wing member (32) and are pivotally secured (38) in the floor of the output tray, with the pivot point spaced inwardly from the wing member. Downward pressure against the wing member thus causes the rail to rotate outward from its closed position, into a recess (24) provided in the side of the output tray. This provides sufficient clearance for the sheet to drop into the output stack. Upon release of the downward pressure, the spring causes the rail member to return to its original closed position.
