5. Relay Motor

The paper feed motor (1) drives feed, pick-up, and separation rollers in trays 1, 2, and 3 via timing belts, clutches (2), and gears. The paper feed motor also drives the vertical transport rollers and the lower relay roller. Drive is transferred to each of the three vertical transport rollers by a vertical transport clutch (3), and to the lower relay roller by the lower relay clutch (4).

The relay motor (5) drives the upper relay roller and LCT relay roller via gears and clutches (6) and (7).

The 2nd vertical transport clutch has a one-way-gear (8). This prevents the clutch from slipping when the knob (9) is turned to remove jammed paper in the paper feed tray and vertical transport area.
