Duplex Module Paper Path - Xerox DocuPrint N24 Service Manual

8.1.6.3 Duplex Module Paper Path

The Duplex Module Paper Path is the physical route that a sheet of paper takes through the Duplex
Module during a Duplex Mode print cycle. Rubber rollers and solenoid activated gates drive and direct
the paper along the Paper Path. The primary purpose of the Duplex Module Paper Path is to accept a
printed sheet of paper from the Fuser exit area, drive that sheet down through the Duplex Module,
effectively flipping over the sheet, and refeed the sheet back into the printer registration area so the
printer can begin to transfer an image onto the second side.
Step 1
The Drum and BTR place an image on side one of a sheet of paper. The Drum/BTR drive the paper into
the Heat and Pressure Rolls. The Heat and Pressure Rolls drive the sheet into the Exit Unit. The Exit
Gate Solenoid toggles the Exit Gate so the paper path runs to the Offset Roll. The Offset Roll drives the
sheet partially into the Output Bin, then stops.
