15. EXIT/REVERSE SECTION
15. 1. General Description
This copier 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.

15. 2. Operation
The paper from the fuser unit is transported to the reverse path by the gate, which is usually directed
toward the reverse path and switched by the solenoid only when the reverse operation is not carried out.
When the trailing edge of the paper has passed through the exit sensor at the fuser unit, the paper transport
speed at the transport path is switched to a high one and switched back in a specified time after that. The
paper is transported to the exit roller with keeping the high speed and discharged to the outside of the
copier. When carrying out a duplex printing, the paper switched back at the reverse path is transported to
the horizontal transport section, which is under the transfer/transport unit and switches the paper transport
speed to a normal one at this time, and it is again transported to the transfer section and fused there. Then,
after the duplex paper has passed through the fuser unit and the gate has been switched, it is discharged
to the outside of the copier by the exit roller without being transported to the reverse path.
