摘要： In a dual engine printing system producing a multipage print job from first and second serially connected printing engines at a common output from the second engine, where the second printing engine has a duplex return path bypassing its printing path and extending substantially therethrough, a high productivity simplex job printing mode is provided in which alternate pages are substantially simultaneously printed in both the first and second printing engines, but the alternate pages printed in the first printing engine are fed to the second printing engine duplex return path to bypass the printing path of the second printing engine and then are automatically interleaved in the common output with the alternate pages printed in the second printing engine. The duplex return path is preferably a bidirectional loop extending above the printing path and driven in a reverse sheet feeding direction for this simplex printing. In an alternate duplex job tandem printing mode, sheets printed on one side in the first printing engine are inverted and fed directly to the printing path of the second printing engine for printing their opposite sides and outputted directly to the common output. Both printing engines may be substantially identical and capable of independent duplex printing with the duplex return path driven in the forward sheet feeding direction.
摘要翻译：在双引擎印刷系统中，从第二和第二串行连接的印刷引擎产生来自第二引擎的共同输出的多页打印作业，其中第二印刷引擎具有绕过其打印路径并基本上延伸穿过的双面返回路径，高生产率提供单面作业打印模式，其中在第一和第二打印引擎中基本上同时打印备用页面，但是打印在第一打印引擎中的备用页面被馈送到第二打印引擎双面返回路径以绕过打印路径第二打印引擎，然后在公共输出中自动地交错，并且打印在第二打印引擎中。双面返回路径优选地是在打印路径上方延伸并沿着该单面打印的反向送纸方向被驱动的双向回路。在备选的双工作业串联打印模式中，打印在第一打印引擎中的一侧的纸张被反转并直接馈送到第二打印引擎的打印路径，用于打印其相对侧并直接输出到公共输出。两个印刷引擎可以是基本相同的并且能够独立地进行双面打印，同时双面返回路径以正向片材进给方向驱动。

摘要： A trail edge transport belt is provided over the elevator platform which receives sheets from a disk stacker. The trail edge transport belt engages and ensures the proper inversion of sheets moved by the rotating disk regardless of the size and weight of the sheet. To ensure that long, light weight sheets do not collapse on themselves prior to inverting, the trail edge transport belt is rotated at a velocity which is greater than the velocity which the sheets are fed to the disk and/or is arranged at an angle to the elevator platform so that a distance between the transport belt and the elevator platform decreases as the transport belt extends away from the rotatable disk.
摘要翻译：在电梯平台上设置有一个轨道边缘传送带，该平台从盘堆垛机接收片材。尾边传送带接合并确保由旋转盘移动的片材的适当翻转，而与片材的尺寸和重量无关。为了确保长的轻质片材在翻转之前不会自己倒塌，则沿着边缘传送带以大于片材被馈送到盘的速度和/或以与电梯平台使传送带和电梯平台之间的距离随着传送带远离可旋转盘而减小。

摘要： An improved sheet stacking apparatus for stacking a wide variety of sheets, especially small sheets, using a rotatable disk stacking unit that receives each sheet in slots defined by fingers on the disks and rotates to invert the sheets. Closely adjacent fixed axis corrugating frictional drive rollers engage the trail edge area of the sheet by the rotation of variable radius disks to larger radius areas thereof which interdigitate with these fixed drive rollers, so that the trail edges of sheets being inverted by the disk contact and are driven by the corrugating rollers. The periphery of the frictional drive rollers is inside of the maximum radius of the disk stacking unit and outside of its minimum radius, so as to be only intermittently interdigitated therewith.

摘要： An apparatus in which a plurality of developer rollers develop a latent image recorded on a flexible photoconductive member. The photoconductive belt is deflected by the developer material to wrap around at least a portion of the first two developer rollers forming wrapped development zones. The last developer roller may either have the photoconductive belt wrapped about a portion thereof, or the photoconductive belt may remain in an undeflected condition. The developer rollers having the photoconductive belt wrapped thereabout rotate in opposite directions. A blanket of developer material is formed between the last two developer rollers. An apparatus of this type optimizes development of the latent image recorded on the photoconductive member.
