• The reverse roller is stopped from forward rotation at timing at which the paper reaches the reverse stop position after the paper exit
sensor has detected the trailing edge of the paper.
• The reverse roller is started to rotate backward at timing at which the preceding paper moves past a predetermined position of the duplex
section.
• The reverse roller is stopped from backward rotation at timing at which the trailing edge of the paper enters the duplex section.

15.5.2 Paper exit roller speed reduction control (C658/C558/C458)
• If the discharge speed at the same speed as process speed is too fast, paper will be discharged forcefully and unevenly in the paper exit
tray.
• Speed reduction control is implemented on the paper exit roller to prevent unevenness in paper.
• The fusing motor and paper exit clutch drives the transport roller. However, drive power is transferred to the reduction gear when paper exit
deceleration clutch is turned ON in the drive state to reduce transport roller speed.
• The paper exit roller speed reduction control is performed only when normal paper is discharged.
