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： A sheet stacking system is provided which includes mechanism designed to compensate for the aerodynamic forces which act on a sheet as it passes from the printer's output port to the floor of the printer's output tray. The system includes a pair of spaced, anti-sail wings which are positioned adjacent the printer's output port so as to controlledly receive just-expelled sheets. The wings are operatively associated with the output tray's floor, and are arranged so that opposite movement thereof results in rear-to-front sequential release of a supported sheet, directing substantially vertical passage of such sheet to the top of an output stack.

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： Several problems of alignment associated with ink-jet printers are alleviated by four aspects. In the first, a reverse bow (B) in the paper (12) is created for printing on single sheets of paper. The reverse bow, which in the transverse axis of the paper, forces the paper flat against the platen (14) by using the paper's own stiffness.In the second aspect, the paper and the carriage (30) are referenced to the same part (the carriage guide (10)). In this configuration, the paper is urged against the underside of the carriage guide off of drive rollers (18), through the reverse bow, and onto the platen, where it is printed. The carriage is referenced to the carriage guide through a slider bump by means of a carriage shaft and gravity.The carraige guide comprises stiff thin sheet metal, which is closely-toleranced and has well-controlled dimensions. Thus, this part is good to reference to, rather than molded-in parts, which are not stiff enough at the required thickness. Straightness is also difficult to achieve at the required thickness with plastic parts.In the third aspect, the platen is allowed to move substantially perpendicular to the plane of the paper to accommodate thicker print media.In the fourth aspect, the platen is maintained a minimum fixed distance from the carriage guide by bumps (38) to ensure that the paper is not pinched between the carriage guide and the platen.
