AL-1551 OPERATIONAL DESCRIPTIONS 7-6
5) At this time, the paper is fed passed the paper entry detection 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, 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. Images are transferred on
the paper, which is separated from the OPC drum by the drum curve
and the separation section.
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.
(2) Manual multi paper feed operation
1) Before paper feed operation, the manual paper feed solenoid
(MPFS) is turned OFF as shown in the figure below.
2) When the PRINT button is pressed, the manual paper feed solenoid
(MPFS) turns on to disengage the manual paper feed latch.
A from the manual paper feed clutch sleeve A, rotating the manual
paper feed roller and the manual take-up roller. At the same time, the
manual paper feed stopper opens and the manual take-up roller is
pressed to the surface of the paper to start paper feeding.
