2Nd Feed Roller Mechanism - Ricoh C217 Service Manual

4.3 2ND FEED ROLLER MECHANISM

[A]
[B]
The lower 2nd feed roller [A] is driven by a stepper motor [B]. The main PCB
controls the 2nd feed roller start timing to synchronize the image on the drum
master and the printing paper.
The stepper motor rotation speed is changed according to the printing
speed. Also, by pressing the image position keys on the operation panel, the
2nd feed timing is changed. If the paper feed timing is delayed, the image is
shifted forward (smaller lead edge margin). If the paper feed timing is
advanced, the image is shifted backward (large lead edge margin).
After the printing paper is caught between the drum and the press roller, the
feed roller stepper motor stops.
