5.2.2 Pickup from the Manual Feed Tray
5.2.2.1 Outline
Paper is picked up from the manual feed tray under the control of the CPU on the DC
controller PCB and using the drive of the main motor (M1). When the manual feed pickup
solenoid (SL1) goes ON, the drive of the main motor (M1) is transmitted as far as the
manual feed pickup roller assembly to rotate the manual feed pickup roller.
The sheets of paper stacked in the manual feed tray are lifted by the work of a spring and
forced against the manual feed pickup roller. Thereafter, a single sheet of paper is separated
by the work of the manual feed pickup roller and the separation pad, and is moved as far as
the registration shutter.
