! Pick-up roller motor: Drops the pick-up roller onto
the stack of originals
! Feed motor: Rotates the pick-up roller
Slide 262
# Just after the original set sensor detects an original, the pick-up roller motor
switches on, to drop the pick-up roller onto the original stack.
# When the leading edge of the original reaches the skew correction sensor, the
pick-up roller motor switches on again, to lift the pick-up roller away from the
original stack.
$ Home position is detected by the pick-up roller HP sensor.
# When the trailing edge of the original passes the skew correction sensor, and
there are still some originals on the tray, the pick-up roller is again dropped onto
the stack of originals.
# Details of the mechanism are as follows:
$ When there are no originals: The pick-up roller remains up (this is the home
position).
$ When an original is placed on the tray: The original set sensor switches on,
and this switches the motor on. The cam releases a lever. The lever rises
and the pick-up roller drops onto the stack of paper. Then the pick-up roller
feeds the paper to the feed belt and separation roller.
$ When the leading edge of the original reaches the skew correction sensor:
The motor switches on again. The cam pushes the lever down until the
actuator enters the sensor and switches off the motor. This stops the pick-
up roller at the home position.
$ When the trailing edge of the paper passes the skew correction sensor with
originals still waiting for scanning: The motor switches on to feed in the next
sheet.
