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。
