5. OPERATION
B. Exit roller pressure/retraction operation
• When the roller pressure/retraction clutch is energized, the lifting cam is rotated a half
turn. The lifting plate is then raised and lowered to complete a pressure/retraction opera-
tion.
• Whether the pressure/retraction home sensor is blocked or unblocked determines the
condition of the exit roller, either pressed or released.
• When the pressure/retraction home sensor is blocked and unblocked, the roller pressure/
retraction clutch is deenergized to stop the operation.
