dure of [8]-5.
F. Adjustment when replacing/cleaning the drum
mark sensor
(1)
Execute simulation No. 44-2 drum mark sensor level adjustment.
Standard value: 204
±
10
G. Adjustment when replacing/cleaning the image
density sensor
(1)
Execute simulation No. 44-3 image density sensor level adjust-
ment.
Standard value: 204
±
10
H. Adjustment when replacing the sensor level
adjustment VR PWB
Execute the procedures of F and G in the above.
1. Note: This model emplyes the high-sensitivity drum,
which requires special care against pre-exposure.
1) Never expose the drum outside the bag. (Keep it in a
black bag.)
2) When istalling this model, avoid facing the front cover
toward a light source or window.
Avoid opening the front cover as far as possible.
2. Other note
1) If starting powder is attached to the density sensor
when replacing the drum/blade, it may cause faulty
operations of the sensor. Be sure to clean and remove
powder.
