SUBJECT:
Additional Information for Exposure Lamp Voltage Adjustment
7. Press the Clear/Stop key.
8. Enter SP95 and set "1" to reset the exposure lamp data for the VL correction.
9. Perform the Light Intensity Adjustment. (See service manual page 5-82.)
NOTE:
The exposure lamp voltage can be adjusted by SP48.
Shifting SP48 by one will shift the voltage as follows:
115 V machine ............................. about 0.5 volt
220 ~ 230/240 V machine .......... about 1 volt
However, if VR401 is not adjusted properly, this voltage shift is changed. As a
result, the exposure lamp corrections (VL correction, VR correction, drum
temperature correction, reproduction ratio correction) will not function properly.
