2.4 Document Pickup/Separation

2.4.1 Basic Sequence of Operation

When the Start key is pressed with an original on the original tray, the machine executes the following sequence of
operation to pickup up the original:
a. Picking Up the Original
When the pickup motor (M1) rotates in reverse and the pickup clutch (CL1) goes on, the pickup roller unit moves
down to start pickup operation. The separation plate and the separation pad are used to prevent multiple feeding of
originals. (After the 2nd original, the pickup unit remains in down position.)
b. Aching the Original
When the original has been moved for a specific number of pulses after the registration sensor has gone on, the
original is caused to arch at the No. 1 registration roller so that it becomes free of any skew.
