CHAPTER 5 TROUBLESHOOTING
1.1.19 Adjusting the Inserter Paper
Set Sensor (S9)
If you have replaced the inserter driver
PCB or the paper set sensor (or, if jams oc-
cur often near the paper sent sensor or the
paper set detection mechanism is faulty),
perform the following:
1) Remove the inserter rear cover.
2) Check t find out if there is paper in the
inserter tray. If any, remove it.
3) Turn on the copier.
4) Turn VR841 until LED843 starts to
flash.
•
The sensitivity of the light-receiving
side of the sensor is adjusted.
•
If the LED remains ON at all times even
when VR843 is turned, suspect a fault
in the sensor. Replace the sensor on the
drive PCB.
5) Turn off the copier.
6) Mount the inserter rear cover.
