EXIT/REVERSE SECTION

14. EXIT/REVERSE SECTION
14.1 General Description
This equipment conducts a paper reverse operation when printing more than 2 sheet of paper or
carrying out a duplex printing. Its reversing device once transports the paper from the fuser unit to the
reverse path where the paper is switched back and reversed, and then transports it to the exit roller or
transfer section.

14.2 Functions
1. Exit/reverse gate
This gate switches the paper from the fuser unit in the direction of the exit roller or reverse path. This
is operated by the gate solenoid (SOL2).
2. Exit roller
The exit roller exits the paper from the fuser unit to the outside of the equipment. This is driven by
the exit motor (M18).
3. Reverse path rollers
The path roller feeds the paper and switches back at the reverse path. This is driven by the reverse
motor (M19) and switches the feeding speed to "high" after the trailing edge of paper goes through
the fuser transport sensor (S9).
4. Reverse section cooling fan-1 and -2 (M24, M25)
These fans are equipped to cool down the reverse section.
5. Reverse sensor-1 and -2 (S23, S24)
These sensors detect the state of paper feeding.
