4. DRIVE MECHANISM
All the tray rollers are driven by the main motor [A] via timing belts, clutches
and a train of gears.
The main motor and the relay clutch [B] are energized at the same time as
the Start key is pressed.
The paper feed clutch [C] 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 frame through the relay rollers.
