Driving power for the by-pass feed roller is provided from the main motor, via the paper feed clutch and the by-pass feed clutch. The feed process begins when the by-pass feed solenoid releases a latch on the by-pass feed clutch, enabling the by-pass feed roller to turn. At this time, two cams on the by-pass feed roller shaft lift the by-pass tray, pushing the paper up against the by-pass feed roller.
The by-pass paper feed roller stops after each rotation due to the on/off movement of the solenoid (when off, spring pressure pulls the latch back down so that it catches on a cog).

| 2. | Metal plate |
In addition to the two cams allowing the by-pass tray to lower slightly after feeding, a curved metal plate (attached to one side of the by-pass feed roller) allows paper to slide past the roller upon completion of each single rotation of the roller while the paper is still feeding.
