PAPER FEED CAM
The operation of this cam results in the up and down action of the paper pickup roller.

This component is driven down onto the Paper Cassette Assembly to advance one sheet of
paper for each copy reproduced. Due to the nature of the assembly construction, this roller
rotates whenever the main motor is
"ON".

Two spring-action clutches are provided within this assembly for controlling the operation
of the paper feed cam and the timing roller.
