16.6 ORIGINAL FEED DRIVE MECHANISM
The two-directional feed-in motor [A] drives the pick-up rollers [B], the
separation rollers [C], and the relay rollers [D]. Three one-way clutches (two
gears [E] and a pulley [F]) control the rollers’ rotation.
Upon receiving the paper-feed signal from the copier, the paper feed motor
turns in the direction shown by the black arrow in the illustration. The relay
rollers are driven by the one-way pulley. The pick-up roller and separation
roller are driven by the one-way gears.
The pick-up roller has a home position sensor [G]. When the sensor detects
that the roller has completed a full turn, the motor starts reversing.
When the motor reverses, the one-way pulley and gear driving the pick-up
and separation rollers become idle and the rollers stop. The relay rollers
continue to turn in the paper feed direction due to the function of the one-way
clutches.
The registration sensor [H] detects the trailing edge of the original and the
paper-feed motor turns off.
