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： A printer capable of producing simplex and duplex copies includes a tri-roller inverter that employs a passive deflector gate downstream from input and output nips of the tri-roller inverter. A sheet driven by the input nip into a reversing chute of the inverter deflects the passive deflector gate to an open position that allows the sheet to enter the inversion chute and after the sheet is past the gate it returns to close deposition, thus allowing the sheet to be driven past it in reverse by a reversing roller. Once the lead edge of the reversed sheet passes the passive deflector gate, a second sheet enters the input nip resulting in two sheets being in the inverter at the same time.

摘要： An idler roller assembly that prevents jams and image deletion in copier/printers by removing any corrugation in sheets before they reach sharp turns includes a shaft onto which idler rollers are mounted with the shaft having a bend in the middle in order to provide a "toe out" condition to steer out any existing sheet corrugation. An alignment member is attachable to the shaft in order to prevent mis-installation of the shaft in its mounting support.
