B. Paper Deck

1. Pick-Up Operation

The copy paper set inside the paper deck is

lifted by the lifter and kept at a specific position.

When the paper deck pick-up clutch (CL11)

turns ON, the pick-up roller rotates to feed copy
paper, with the pick-up/feeding roller and the sep-
aration roller making sure that only a single sheet
of paper is fed forward.

When the paper deck pick-up sensor (Q35)

then detects the copy paper, the roller releasing
solenoid (SL7) turns ON to move the pick-up roller
away from the surface of the paper.

The feeding roller rotates when the paper deck

feeding roller clutch (CL8) is ON to move copy
paper to the registration roller.

The paper deck paper trailing edge sensor

(Q44) is used to detect passage of copy paper,
upon which the second and subsequent pick-up
operations are initiated.

To prevent skew movement, the copy paper is

made to form an arch while the registration roller
is at rest. To make sure that the copy paper will
not arch excessively, the paper deck feeding roller
stop clutch (CL18) is turned ON, thereby forcing
the paper deck feeding roller OFF. The copy paper
is then controlled so that its leading edge match-
es the image on the photosensitive drum.
