Registration Roller Drive

The lower registration roller [A] is driven by a stepper motor [B] (the registration
motor). The CPU controls the registration roller start timing to synchronize the
printing paper with the image on the master on the drum.
The stepper motor rotation speed depends on the selected printing speed. By
pressing the image position keys on the operation panel, the registration motor
start timing is changed.
After the printing paper is caught between the drum and the press roller, the
stepper motor stops.
