Switching mechanism for turnover/paper exit

• The original transferred from the transport section will switch back or exit by the exit roller
and the exit switch back roller.
• The exit switch back roller is driven by the exit motor.
• During the turnover operation, the exit rolls are pressed against, or retracted from, the
exit roller to prevent the leading and trailing edges of the original from being pinched
between the roller and rolls.
• Pressure and retraction operations are performed by energizing or deenergizing the
retraction solenoid.
• When the retraction solenoid is energized, the arm is operated to move the exit rolls
away from the exit roller.
