Paper path Paper input The device receives paper from the printer at different speeds-106, 117, or 147 mm/second-depending on the printer in use. Flipper Paper arrival is sensed by FLEntry1, which activates the flipper motors. For face-up printing, the flipper simply delivers paper sensed by FLEntry to the face-up bin. Otherwise, the flipper changes page orientation from face-up to face-down and delivers paper sensed by FLExit to the accumulator assembly. Accumulator assembly (stapler/stacker ONLY) The accumulator assembly collects and registers print jobs/mopies from the flipper (sensed by GWSens), sends them to the carriage assembly for stapling, and delivers them to the stapler bin (sensed by ACExit). Offset module (stacker ONLY) The offset module collects and registers print jobs/mopies from the flipper (sensed by FLExit), offsets them (if selected), and delivers them to the stacker bin (sensed by Exit). 214 Chapter 5 - Theory of operation EN
