First, the paper transport motor switches on, and then the pickup solenoid switches on.
- The feed motor switches on and rotates the feed roller.
- The gear train rotates the pickup roller which feeds the first sheet from the top of the stack.
- The separation roller (equipped with a torque limiter) closes with the feed roller to form the nip where each sheet feeds.
- If more than one sheet of paper feeds, there will be no resistance between the extra sheet and the sheet above, and this lack of resistance will cause the separation roller to reverse slightly and flip the paper back into the paper tray.
- Next, the paper feed sensor (a photosensor) detects the paper, and then switches off the paper feed motor and pickup solenoid to raise the pickup roller and release the sheet of paper.
- The pressure slide arm lowers and raises the separation roller when the tray is removed and inserted so jammed paper can be removed easily.
