    摘要: A second feed roller of smaller diameter than a first feed roller is included in a media handling system. A print zone is located adjacent to the second feed roller away from the first feed roller to lower the location of the print zone. During ejection, a pivot mechanism moves from a first position adjacent to the printhead to an intermediary position. This causes arms to extend and rails to retract. The motions then pause and/or reverse, prior to full extension and full retraction. Next, the pivot mechanism moves to a second position causing the arms to fully extend and the rails to fully retract. The varied motion (e.g., pause and/or reversal) assures that the arms push at an edge of the media sheet to reliably move a media sheet into an output tray without the media sheet sailing from the printer.

    摘要: Method and apparatus for storing accessories inside a printing device, wherein the apparatus includes a storage enclosure, which is secured pivotally to the housing of the printing device, and which is capable of assuming at least one open position and one closed position. The storage enclosure is substantially housed within the carriage swept volume, when it is located in the closed position, without interfering with the path of travel of the carriage assembly, when it is in the open position. A cover protects the inner printing mechanism when the storage enclosure is in the open position. A catch mechanism retains the storage enclosure in stable open and closed positions.

    摘要: A carriage-actuated venting system for a print head of an inkjet printer includes a print head cap, selectively closable over the print head of the ink jet printer. A vent port is in fluid communication with the print head cap and vents the print head when the print head cap is closed over the print head. A movable shaft is engageable by a movable carriage of the ink jet printer. A vent actuator is coupled to and movable with the shaft to close the vent port and restricts venting of the print head through the print head cap.

    摘要: A media feed mechanism includes a picking device, a first feedroller and a second feedroller. The picking device picks a sheet of media from a media source. The first feedroller moves the sheet of media along a feed media path. During a skew correction phase, the first feedroller rolls in a forward direction feeding the sheet of media forward and the second feedroller turns in a reverse direction preventing the sheet of media from progressing past a nip of the second feedroller. This results in skew correction. After skew correction is performed, the second feedroller turns in the forward direction advancing the sheet of media for printing.

    摘要: A sheet media handling system is provided for use in a sheet processor having support structure which is configured to accommodate reliable sheet pick-up and to minimize the sheet processor's size, while still offering suitable access to the media sheets. The handling system includes upper and lower support structure, the lower support structure supporting sheets for delivery to an input port, and the upper support structure supporting sheets which are expelled from an output port. The lower support structure includes a drawer configured for translation between a fully-dosed drawer position and a fully-open drawer position. Correspondingly, the upper support structure includes a door configured to pivot between a fully-closed door position and a fully-open door position. An overcenter mechanism is employed to bias the drawer either into a fully-closed drawer position or toward a fully-open drawer orientation.

    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。
