Paper Path of Duplex Unit
When duplex printing, the paper is forwarded by the pickup roller to the printer simplex area
and printed first on the front side. The single side printed paper, then, arrives at the exit
roller thru the fusing area, and is fowarded to the duplex area by operating the solenoid and
driving the normal/reverse rotation bracket. The paper transferred to the duplex area goes
past Simplex area again to be printed on the other side and is eventually exited on the exit
tray by the exit roller.
