Phaser 3450 Laser Printer Service Manual
Paper Path of the Printer
Papers that meet the specifications may be fed from Trays 1 and 2, or the optional
Tray 3. If you use thick paper (from the RCP Menu) with a weight of more than 105
g/m
2
(60 lb), you must insert the paper into Tray 1 and select the paper type. Paper
will exit the printer to the face down top tray. A door at the rear of the printer provides
access for jam clearance.
The diagram below shows the paper path through the Phaser 3450 Laser Printer and
identifies the major components. The simplex paper path is shown in black and the duplex
path is shown in grey.
Duplex Paper Path
When duplex print mode is selected, the paper is first printed on side one. When the
image on side one of the paper is fused, as detected by the Fuser Exit Sensor, the drive
motor reverses. The paper is fed through the duplexer and back up to the feed roller
with side two positioned for printing.
