Abstract: The device includes a corona generating device arranged to charge the copy sheet for establishing a transfer field that is effective to attach the developed image from the photoconductive surface to the copy sheet. A blade is moved from a non-operative position spaced from the copy sheet, to an operative position in contact with it. The blade presses the copy sheet into contact with at least the developed image on the photoconductive surface. This substantially eliminates any spaces between the copy sheet and the developed image during transfer of the developed image from the photoconductive surface to the copy sheet.

Abstract: This invention discloses a method and apparatus for properly placing copy sheets from a high speed copy machine into an exit tray. The invention utilizes a variable speed motor to control the rollers which reside at the end of the paper path. One or more paper guides mounted to the drive rollers, enable the motor to operate over a wide range of speeds, yet still work efficiently. The motor accelerates to its highest speed as the copy sheet enters the nip between the drive and idler rollers, and is decelerated to its slowest speed as the trailing edge of the copy sheet exits the nip. The trailing edge of the copy sheet then moves off of the roller and onto the paper guide. The speed of the motor can then be increased without having to wait for the copy sheet to move into the output area. This substantially reduces the period of time required to reproduce copies.

Abstract translation: 本发明公开了一种将复印纸从高速复印机适当地放入出纸盘的方法和装置。 本发明利用变速电动机来控制位于纸路径端部的辊子。 安装到驱动辊上的一个或多个纸张导板使得电动机能够在宽范围的速度下操作，但仍然有效地工作。 当复印纸进入驱动器和惰辊之间的辊隙时，电机加速到最高速度，当复印纸的后缘离开辊隙时，电机减速到最慢的速度。 然后，复印纸的后边缘从辊子移开并移动到纸张导板上。 然后可以增加电机的速度，而不必等待复印纸移动到输出区域。 这大大减少了复制副本所需的时间。

Abstract: A paper conditioner (100) to control image dependent curl which uses one or more counterrotating transfer rollers (102, 103) which are initially spaced from their respective back-up rollers (104, 105) in the intercopy gap, and which come together as the lead edge enters the nip area, and separates when the trail edge is about to pass. This permits the rollers to have a less demanding runout tolerance by bringing the rollers together when the sheet is in the nip, and then articulating the rollers apart in the intercopy gap.

Abstract: An apparatus for registering a sheet with a developed image on a moving surface. The apparatus includes a transfer station, detector, memory, and a registration transport. The detector is located at the transfer station and generates a registration signal in response to a sheet edge and a registration portion of the developed image. The memory stores sheet position factors and responds to the detector to update the factors. The registration transport communicates with the detector and the memory to move the sheet to the transfer station in registration with the developed image.
