2-10 Phaser 5500 Printer Service Manual
Duplex Path
If duplex printing is selected, the Exit 2 Exit Gate Solenoid switches the position of
the Exit gate to direct paper out Exit 2. The Exit 2 Motor reverses direction and feeds
the paper into the Duplex Unit. The paper pauses briefly, detected by the Wait Sensor,
then continues through the Duplex Unit to the Registration Roller for printing on the
opposite side. The purpose of the Duplex Unit is to accept a printed sheet of paper
from the Fuser exit area, effectively flipping the sheet over, wait a period of time for
the second side to develop, then reinsert the sheet back into the printer registration
area to receive an image on the reverse side. The Duplex Unit provides duplex
printing for paper fed from all available paper trays except the Envelope Tray, which
cannot be duplexed.
