B. Operational descriptions
Paper is fed from each paper feed section and transported to the registration roller by the transport rollers. ON/OFF control of each transport
roller is made by the paper transport clutch. The registration roller controls the relative positions of transported paper and the transfer image.
The registration roller is driven by the transport motor. The relative positions of paper and the transfer image are determined by the ON timing
of the transport motor.
