    • 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。

    • A printer and method of printing wherein a preview mode conveys media through the printer in a manner that avoids the possibility that the media can contact a print head. A hold-down system of the printer and/or media transport generates a hold-down pressure applied to the substrate media in the direction of the first media transport. A precurler unit applies a predetermined degree of curl to the substrate media. A media height sensor determines the height of the substrate media above the first media transport under the influence of the hold-down pressure. A print head array marks the substrate media with an image in the marking zone, and an actuator adjusts the relative spacing between the print head array and the first media transport. The gap between print head and the media is adjustable in view of the measurements.
    • 一种打印机和打印方法,其中预览模式以避免媒体可以接触打印头的可能性的方式传送介质通过打印机。 打印机和/或介质传输的压紧系统在第一介质传送的方向上产生施加到基板介质的压紧压力。 前体单元对基材介质施加预定程度的卷曲。 介质高度传感器在压紧压力的影响下确定基板介质在第一介质输送器上方的高度。 打印头阵列用标记区域中的图像标记基板介质,并且致动器调节打印头阵列和第一介质传输之间的相对间隔。 考虑到测量,打印头和介质之间的间隙是可调节的。
