3. After about 0.1 sec from when the main motor start rotating,

the tray paper feed solenoid (PFS) turns on at a moment.
This disengages the paper feed latch from the projection of
the clutch sleeve, transmitting rotation of the pick-up drive
gear to the paper feed roller shaft, rotating the pick-up roller
to feed the paper.

4. After more than half rotation of the pick-up roller, the paper

feed latch is brought in contact with the projection of the
clutch sleeve, stopping rotation of the pick-up roller.

5. At this time, the paper is fed passed the paper entry detec-

tion switch (PPD1), and detected by it. After about 0.15 sec
from detection of paper by PPD1, the tray paper feed
solenoid (PFS) turns on so that the clutch sleeve projection
comes into contact with the paper feed latch to stop the
pick-up roller. Then the pick-up roller rotates for about 0.15
sec so that the lead edge of the paper is evenly pressed on
the resist roller, preventing against skew feeding.

6. To release the resist roller, the tray paper feed solenoid and

the resist solenoid are turned on by the paper start signal to
disengage the resist start latch from the clutch sleeve
projection, transmitting rotation of the resist drive gear to the
resist roller shaft. Thus the paper is transported by the resist
roller.

7. After the resist roller starts rotating, the paper is passed

through the pre-transfer guide to the transfer section. Im-
ages are transferred on the paper, which is separated from
the OPC drum by the drum curve and the separation sec-
tion.

8. The paper separated from the drum is passed through the

fusing paper guide, the heat roller (fusing section), POD
(paper out detector) to the copy tray.
