GP 3.9 Fan Control

The printer switches between two Fan speeds.
• High Speed, when the Main Motor Assembly is on.
• Low Speed, when the Main Motor Assembly is off.
When printer power is switched on, or when an Interlock Switch is actuated (after being deac-
tuated), the Fan runs at High Speed for one second, then switches to Low Speed.

The Paper Path for Duplex Printing (Figure 1) and (Figure 2)
During the duplex printing, the printer prints the first side of the paper. Then the Exit Assembly
reverses direction and re-feeds the paper to the Duplex Assembly. The paper is transferred
through the Duplex Assembly and fed again to the Paper Handler Assembly. When the paper
reaches the registration position, the second side of the paper is already face up. Then the
printer starts to print the second side of the paper, and transfers the completed duplex sheet to
the Output Tray.
During duplexing to ensure proper collation of the output documents, even sides are printed
first.
