Paper feed control
• The pick-up roller [7], paper feed roller [6], and registration roller [3] are driven by the paper feed motor
(M301).
• M301 drives in both directions, forward and reverse. When it drives in forward, the pick-up roller and the
paper feed roller rotate to transfer papers, while the registration roller does not rotate.
• When M301 drives in reverse, only the registration roller rotates to feed papers while the pick-up roller goes
up to the shelter, and one-way clutch keeps the paper feed roller from rotating.
• The separation roller, which is not driven by the motor, is provided with a torque limiter. When a piece of
paper is transferred, the separation roller moves in synchronization with the paper feed roller. On the other
hand, when two or more papers are fed, the separation roller remains stationary and separates the papers.
• The registration clutch (MC301) functions as the brake to stop the registration roller, not to turn ON or OFF
the drive force transmission.
• The registration sensor (PS301) [4] and the timing sensor (PS302) [2] detect the timing of the original.
