Pick-up and Feed
Separation Roller
Solenoid
Describe this mechanism.
To start paper feed, the separation roller solenoid and pick-up solenoid both
turn on. There is no feed clutch, because each tray has its own motor.
When the separation roller solenoid turns on, the separation roller contacts
the paper feed roller.
When the pick-up solenoid turns on, the pick-up roller drops onto the top
sheet of the paper stack.
The feed motor turns forwards, to drive both the feed roller and the grip roller.
When the paper feed sensor detects the leading edge of the paper, the pick-
up solenoid switches off and the pick-up roller lifts.
Paper is separated using the FRR principle.
