Paper Path Through Duplex Unit

Duplex Unit Fan

2-60
The following illustration shows the paper path through the Duplex Unit with the
Duplex Unit Base Attachment, and the paper path through the Duplex Unit with
the 500 Sheet Feeder attached.
The Duplex Unit Fan moves air through the unit to keep the temperature of the
LVPS from rising.
The Duplex Unit Fan operates at full-speed at the start of a duplex operation, and
then slows to half-speed after the duplex operation ends. The fan is off when the
Duplex Unit is not in use.
