HCI pickup mechanism
A pickup-arm method provides high-speed paper pickup and high-volume printing. The rotating HCI
pickup roller is pressed down to the paper stack surface to feed the paper one sheet at a time.
The HCI pickup roller is attached to the pickup arm, and the arm is typically held at the original position
by the pickup cam. When the HCI pickup solenoid (SL1) is turned on, the pickup cam rotates and lowers
the HCI pickup roller onto the paper surface.
The pickup operations for the 3 x 500-sheet HCI center and bottom cassettes are the same as for the
top cassette.
