Pick-up Roller Up/Down Movement
The pick-up roller is raised by a solenoid. When the leading edge of the paper passes
between the feed roller and separation roller, the CPU energizes the solenoid and the pick-up
roller is lifted out of the paper path. This copier has three pick-up solenoids. Two solenoids [A]
are used for the first and second cassette paper feed. The other solenoid [B] is used for
manual paper feed. The lift timing of the upper and lower pick-up rollers is different.
After the trailing edge of the paper passes under the pick-up roller, the pick-up roller drops
onto the paper stack in preparation for the next copy cycle.
