4. DRIVE MECHANISM
All the tray rollers are driven by the main motor [A] via timing belts, clutches
and a train of gears.
Drive is transmitted to the timing pulley [B] through the timing belt [C], relay
clutch [D] and the gears.
Paper Feed Unit 1:
The drive from the timing pulley is transmitted to the unit through the timing
belt [E].
Paper Feed Unit 2:
The drive from the timing pulley is directly transmitted to the unit.
Paper Feed Unit 3:
The drive from the timing pulley is transmitted to the unit through the timing
belt [F].
The main motor and the relay clutch are energized at the same time that the
Start key is pressed.
The paper feed clutch is energized 300 ms after the main motor starts to
rotate. When the paper feed clutch for the selected paper tray is energized,
paper is fed from the paper tray to the main machine through the relay rollers.
