CHAPTER 7 PICK-UP/FEEDING SYSTEM
7-5
B.
Retry pick-up
When paper is not picked-up even when the pick-up roller is rotating, the retry pick-
up operation occurs.
The DC controller PCB’s CPU counts the time from when the paper solenoid
(SL301) comes ON. If the pick-up sensor (PS303) cannot detect the paper’s leading
edge within a designated period of time, the pick-up solenoid comes ON again and the
pick-up operation is retried. Even when the retry pick-up is actuated once, if the pick-up
sensor does not detect the paper’s leading edge within the specified period of time, it
judges there is a jam, and a jam message is displayed on the control panel’s display.
