3.4 Document Pickup/Separation

3.4.1 Outline

0013-3478

The pickup roller unit is butted against the original, and the pickup roller is rotated to pick up an original. The
pickup roller unit is moved up/down by the pickup motor (M3), and the pickup roller is rotated by the separation
motor (M4) and the separation clutch (CL).
Originals are separated by the separation roller and the separation belt with the help of the feeding roller. The
rollers and the belt are driven by the separation motor (M4) and the separation clutch (CL).
The separation assembly is equipped with a separation sensor (S4) and a skew sensor (S5) to monitor the
movement of originals.
