2.1.1 PICK-UP ROLLER RELEASE MECHANISM
When the original set sensor is off (no original on the original tray), the pick-up
roller stays in the up position.
When the original set sensor turns on (or when the trailing edge of a page passes
the entrance sensor while pages remain on the original tray), the pick-up motor [A]
turns on. The cam [B] rotates away from the pick-up roller release lever [C]. The
lever then rises and the pick-up roller [D] drops onto the original.
When the original reaches the entrance sensor, the pick-up motor turns on again.
The cam pushes the lever down, and the pick-up roller rises until the pick-up roller
HP sensor [E] detects the actuator [F].
