4.2 SEPARATION AND PAPER FEED MECHANISM

Originals are separated using the friction belt [A] and the feed roller [B].

When the copier sends a signal to the DF to feed in the original, the feed-in

motor [C] starts rotating (clockwise) to drive the pick-up [D], feed and pull-out

[E] rollers. A one-way bearing stops the friction belt from rotating. Originals

are separated and fed in one by one because the resistance of the stationary

friction belt is greater than the friction between pages of the original.

When the registration sensor [F] detects the separated first original, the

feed-in motor reverses (counter clockwise), and the drive is transmitted only

to the pull-out rollers due to a one-way bearing. In this condition, the pull-out

rollers are still rotating in the same direction, and they feed the original to the

exposure glass. The motor turns off when the trailing edge of the 1st original

has finished passing over the sensor.

To prepare the next original, the feed-in motor turns clockwise to separate

the second original and the motor turns off when the registration sensor

detects the second original. When it is time for the second original to be fed

to the exposure glass, the feed-in motor turns counter clockwise.
