15-5. Paper Separating Mechanism
The tray has fingers that separate the top sheet of paper from the rest of the paper stack
at paper take-up, The Fingers are fitted to the right front and rear corners of the Draw-
er. When the Paper Take-Up Roll starts turning to take up the top sheet of paper,
its turning force is directly transmitted to the top sheet of paper as it is in direct con-
tact with the Paper Take-Up Roll. That force overcomes the block of the Fingers,
causing the top sheet of paper to ride over the Fingers and be fed out of the Drawer
into the copier.
As to the second sheet of paper, the paper transport force obtained through friction
with the top sheet of paper is weak and does not allow the second sheet of paper
to ride over the block of the Fingers. Hence, the second sheet of paper remains
stationary with the rest of the paper stack in the Drawer.
When there are only two sheets of paper left in the Drawer, the bottom sheet can
be fed with the top one if the friction of the Paper Lifting Plate is weak. The Friction
Plate affixed to the Paper Lifting Plate prevents this from happening.

15-6. Paper Take-Up Roll
Since the Paper Lifting Plate is raised at all times by the Paper Lifting Springs, paper
is wedged in the mechanism when the Drawer is slid out of the copier if the Paper
Take-Up Roll is round in shape. So the Take-Up Roll is semicircular and the circular
part of the Roll is positioned on top at times other than take-up. For convenience,
we call this position of the Paper Take-Up Roll the [etracted(position.
The Paper Take-Up Roll is grooved to keep good friction even under heavy loading.
The Paper Take-Up Roll is driven when the Paper Take-Up Solenoid (SL2) is
energized. The Roll is turned one complete turn for each single sheet of paper.
The Paper Transport Sensor (PC2) is used to detect whether a sheet of paper has
been properly taken up or not.
