- Code: 10-01, 10-02, 10-04, 10-40
- Description: Misfeed at manual bypass paper feed section
10-01 The leading edge of the paper is not turned ON (unblocked) the registration sensor/1 (PS1) even after the lapse of a given period of time after the manual bypass tray starts to feed paper.
10-02 For paper fed from the manual bypass tray, loop forming has not been complete before a sheet enters the registration roller because the rise timing of load to perform registration is earlier than the rise timing of load to form a loop.

10-40 For paper fed from the manual bypass tray, the image write start signal permit continues to be disabled for a predetermined period of time after the timing of the image write start signal output. - Causes: • Paper feed motor (M22)
