摘要： In a sheet feeding system for a copier, for the sequential separation and feeding of individual sheets from a stack of sheets by an impact type sheet feeder, there is provided a plural mode stack repositioning system for automatically repositioning the top sheet of the stack of sheets into an optimum feeding position relative to the impact sheet feeder, which optimum feeding position is closely adjacent to, but slightly spaced below, a maximum limit position of the top of the stack. This stack repositioning system further provides a retard repositioning mode in which the stack of sheets is automatically lowered into a retard position after each sheet feed has been initiated, which retard position is substantially below the optimum feeding position, in response to a sheet feeding sensor detecting a sheet being successfully fed from the stack by the impact sheet feeder and acquired by a take-away feeding system. Fixed position frictional sheet retard members are positioned to frictionally engage the next underlying sheet of the stack in this retard position to resist double sheet feeding. These retard members are not in the sheet feeding path in the optimum or initial sheet feeding position of the stack. There are also provided arrangements for arcuately deflecting the sheets being fed out to and by the take-away feeding system to provide increased normal force against the retard members in the retard position of the stack.
摘要翻译：在用于复印机的纸张馈送系统中，为了通过冲击式送纸器从一叠纸张顺序分离和输送单张纸张，提供了一种多模式纸盘重新定位系统，用于自动重新定位纸张堆叠的顶部纸张进入相对于冲击片进给器的最佳进给位置，该最佳进给位置紧密地邻近堆叠顶部的最大极限位置但稍微间隔开。该堆叠重新定位系统进一步提供延迟重新定位模式，其中响应于纸张馈送传感器检测，纸张堆叠在每个纸张进给已经开始之后自动下降到延迟位置，该延迟位置基本上低于最佳供给位置通过冲击片进给器从纸堆成功地进给并通过收纸送料系统获取的纸张。固定位置的摩擦片材阻挡构件定位成在该延迟位置摩擦地接合堆叠的下一个下层片材以抵抗双页进纸。这些延迟构件不在堆叠的最佳或初始供纸位置的片材进给路径中。还提供了用于将被送出和被取出供给系统送出的片材弧形偏转以提供叠层延迟位置中的延迟构件的增加的法向力的布置。

摘要： A segmented flexible heater disposed adjacently to a paper path in a printing machine for heating a recording medium before printing and during printing. The segmented flexible heater includes a curved first portion for preheating the paper and a substantially planar second portion for heating the paper in a print zone wherein the second portion generates heat energy having a temperature greater than the heat energy generated by the first portion. The first portion includes apertures for accommodating drive rollers for moving the recording medium into the print zone area heated by the second portion. The apertures in the flexible heater provide for continuous heating of the recording medium before and during heating. The second portion is preferably at least two printing swaths wide to prevent thermal shock to the portion of the printing medium being printed on.

摘要： An automatic printing machine for producing successive duplex prints forms an image on a first side of successive print substrates, transports successive substrates having images on a first side through the machine to form images on the opposite side of the substrate. The substrate transport path inverts each successive substrate twice about an axis perpendicular to the direction of the path and has a side shifting inverter to invert successive substrates once about an axis parallel to the path direction and includes a first substrate guide with a top sheet insertion baffle and a bottom sheet insertion baffle defining a portion of the substrate transport path, one of the baffles having at least one aperture for a rotatable segmented drive roll having a flat segmented portion and a curved segmented portion, the curved portion extending through the aperture when the drive roll is rotated to be in substrate driving engagement with the remaining baffle, the flat segmented portion of the drive roll not extending through the aperture when adjacent the aperture. The inverter further include a direction reversing arcuate substrate guide to guide a substrate around a direction reversing path about an axis parallel to the path direction and a transport to transport a substrate through the arcuate guide. In a preferred embodiment the inverter portion of the duplex path is in a removable cassette which is interchangeable with a print substrate cassette.

摘要： An improved document registration system in a copier having a platen for exposing documents includes a registration edge at the forward end of the platen and at least one foam document aligning belt located adjacent to and above the registration edge. The alignment belt is adapted to extend a short distance over and conform to the registration edge so that documents can be driven toward the registration edge with positive control and thereby reduce up-curl and registration edge jumping.

摘要： A liquid ink printing machine, for forming an image on a recording medium moving along a path, including an arrangement for reducing media feedhead loads on media being fed in the printing machine. This is accomplished by using the printing machine's printhead carriage to contact a lever which will lower a paper tray holding the media once media being fed has reached an advance nip past the feedhead, thus reducing drag on the media being fed.

摘要： The present invention is directed towards an optical scanning system for an electrophotograhic printing machine wherein a lens control system is provided to enable lens movement independent of lens movement which occurs during magnification changes. The lens carriage is adapted to be independently driven in one or two directions dependent on the mode of operation selected by the operator and under the control of a system controller which analyzes the inputs which determine lens position (open platen or document feeder mode, output copy size, magnification).
