Abstract: The method of purging undesirable copy sheets from an image processing apparatus having a xerographic process for producing images on copy sheets, the apparatus including a plurality of copy sheet sources, a copy sheet drive, a purged copy sheet location, and a controller for directing the xerographic process, including the steps of monitoring the timer for a given time period; detecting by the controller said given time period; checking the copy sheet sources for the presence of a purgeable copy sheet; responding to the detection of said given time period and the checking of the copy sheet sources to operate the copy sheet drive, and purging undesirable copy sheets to the purged copy sheet location.

Abstract: A modular, customer installable bypass paper transport allows printed output from a printer to bypass an output tray of the printer and pass directly into a separate finisher so as to ensure no detrimental impact on the IOT of the printer when the units are coupled or decoupled. The bypass transport fits into an output tray of the finisher and is powered by the printer. Alignment is accomplished by the use of two switches on the mating end of the bypass transport that have plunger type actuators that are actuated with minimal contact with the separate finisher in order to indicate correct or incorrect docking of the separate finisher with the bypass transport.
