10.2.3 Paper Pickup Operation

0013-1195
The pickup unit consists of pickup and transport rollers. When the Start Key signal or Original Feed signal is
input, the ADF motor (M2001) turns in the normal direction and then the pickup solenoid (SL2001) turns on.
The pickup unit lowers and the pickup and transport rollers rotate to feed the paper. The shutter moves up in
conjunction with the pickup unit. A separation pad is used to prevent multiple sheets from being fed at the same
time.
When the original reaches the registration roller where is it looped, the pickup solenoid (SL2001) turns off and
the pickup unit roller rises. Next the registration solenoid (SL2002) turns on and the original is fed by the
registration roller. At this time, the pickup roller drive shaft which is rotated via the spring one-way clutch is
stationary at the highest position in the pickup unit. The pickup roller incorporating a one-way clutch is rotated
by the friction against the paper.
