摘要： A novel ink-jet printer (10) is provided. The printer 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 resulting printer is easy to manufacture, has reduced complexity by eliminating components in the paper drive mechanism and is lower in cost.

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.

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.

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 method for correcting the skew between the leading edge of a sheet of paper and the nip of a roller assembly in a printing mechanism includes the steps of advancing a sheet of paper into the nip and slightly therebeyond. The rollers are then rotated in reverse, causing the paper to retract from the roller assembly, with the angle and weight of the paper maintaining the leading edge within the nip. As the rollers continue to rotate backwards, the paper jiggles or dances allowing the leading edge to settle parallel with the nip under its own weight. The paper is then readvanced through the roller assembly with its leading edge parallel to the nip. A mechanism applies a drag force to the paper when the paper is being retracted from the roller assembly to keep the leading edge of the paper in the nip.A single motor control apparatus includes a processor-controlled drive motor, a drive roller assembly, a pick roller assembly and a gearing arrangement coupling the drive motor to the roller assemblies, for selective control of the timing, speed and rotational direction thereof to achieve the above described method.
摘要翻译：用于校正纸张的前缘和打印机构中的辊组件的辊隙之间的偏斜的方法包括以下步骤：将一张纸推进到辊隙中并稍微移动。然后将辊子反向旋转，使得纸张从辊组件中缩回，纸张的角度和重量保持辊隙内的前缘。当滚筒继续向后旋转时，纸张跳动或跳舞，允许前缘在其自身重量下与辊隙平行地平齐。然后纸张通过辊组件进行阅读，其前缘平行于辊隙。当纸张从辊组件收回时，机构将纸张拖曳到纸张上，以将纸张的前缘保持在辊隙中。单个电动机控制装置包括处理器控制的驱动电动机，驱动辊组件，拾取辊组件和将驱动电动机联接到辊组件的传动装置，用于选择性地控制其正时，速度和旋转方向，以实现上述方法。
