ADJ 3
Image density sensor
adjustment
Before executing this adjustment, check to confirm the following
items.
* Check to confirm that the color image density sensor (image reg-
istration sensor F) and the black image density sensor (image
registration sensor R) are clean.
* Check to confirm that the image density sensor calibration plate
is clean.
* Check to confirm that the transfer belt is clean and free from
scratches.
3-A Image density sensor adjustment
The transfer belt surface are used to make the sensitivity adjust-
ment of the color image density sensor (image registration sensor
F) and the black image density sensor (image registration sensor
R).
This adjustment executes automatically at the outset of registration
adjustment operation and process control operation as well as
SIM44-2.
Normally, therefore, it is not required to perform this adjustment. It
is performed only when the sensor is replaced or when the adjust-
ment result is checked.
1) Enter SIM44-2 mode.
2) Press [EXECUTE] key.
The sensitivity adjustments of the color image density sensor
(image registration sensor F) and the black image density sen-
sor (image registration sensor R) are automatically performed.
After completion of the adjustment, the adjustment result is
displayed and [EXECUTE] key returns to the normal display.
If the adjustment is not completed normally, "ERROR" is dis-
played.
When an error occurs, check the following sections for any abnor-
mality.
• Color image density sensor (image registration sensor F)
• Black image density sensor (image registration sensor R)
• PCU PWB
• Transfer belt (dirt, scratch)
• Transfer belt cleaner
If any abnormality is found, repair and adjust again.
If an error occurs, the adjustment result is not revised.
