EXIT/REVERSE SECTION
14 - 2
14.3 Driving of Exit/Reverse section
The paper feeding roller in the exit/reverse section is driven by the following mechanism.
• Exit motor (G19)
→
Gears (G21, G20, G19)
→
Exit roller
• Reverse motor (T21)
→
Timing belt and Pulleys (T23, T23)
→
Reverse path roller
14.4 Operation
The paper from the fuser unit is transported to the reverse path by the exit/reverse gate, which is
usually directed toward the reverse path and switched by the gate solenoid (SOL2) only when the
reverse operation is not carried out.
When the trailing edge of the paper has passed through the fuser transport sensor (S9), the paper
transport speed at the reverse 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 equipment. 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 exit/reverse gate has been switched, it is discharged to the outside of the equipment by the exit
roller without being transported to the reverse path.
