    • A printing system sheet feeder apparatus and method is provided. The printing system feeder includes a front nudger roll positioned near the leading edge of the top sheet of a sheet stack and the front nudger roll is capable of advancing the top sheet. In addition, the printing system sheet feeder includes a separation nip aligned with the front nudger roll, the front nudger roll being capable of receiving the top sheet advanced by the front nudger roll and advancing the top sheet in a direction away from the front nudger. A rear nudger roll is positioned near the trailing edge of the top sheet and is capable of advancing the sheet directly below the top sheet while the top sheet is being advanced by the front nudger roll and/or separation nip, thereby increasing the overall sheet feeding rate to the printing system.
    • 提供了一种打印系统片材馈送装置和方法。 打印系统进纸器包括位于片材堆叠的顶片的前边缘附近的前微型滚筒,并且前导板辊能够推进顶片。 此外,印刷系统片材进给器包括与前部微型滚筒对准的分离辊隙,前部微型滚筒能够接收由前部微型滚筒推进的顶部片材,并且使得顶部片材沿远离前部微型机器的方向前进。 后部微型滚筒位于顶片的后缘附近,并且能够通过前部微动辊和/或分离辊隙使片材前进,从而使片材直接在顶片下方推进,从而增加整个片材进给 速率到打印系统。
