2.2.1.4 Timing Roller
Timing roller adjusts paper skewing carried by the paper feed mechanism and
rotates as the top of image on the transfer belt comes on the end of paper.
†
Timing sensor (PC5) detects that the top of paper carried by the paper feed
mechanism reaches the timing roller.
†
When it detects paper, turns off the intermittent roller solenoid and pauses
carrying paper.
†
Timing roller starts rotating when a certain amount of time passed after
timing roller solenoid (SL5) is ON. If it fails to do so, load paper again to
prevent paper load failure (only for color printing).
†
When paper is longer than specification or smaller than A5 size, it detects
paper size error.
