Adj of Bk Pre-exposure LED current
To adjust the current of the Cleaning Pre-exposure LED (Bk).
As the current is increased, light intensity of the LED becomes strengthened so the potential of
the Photosensitive Drum is decreased.
Set 15 (the maximum current) when drum ghost (uneven density at intervals of drum
circumference) occurs.
If the image is still dark (potential is not applied well) even though adjustment has been made with
VCONT-K or VBACK-K, decrease the value a little at a time from 13 while checking the adjustment
result (the current is decreased in increments of approx. 7%).
- When drum ghost occurs
- When the image is still dark even though contrast potential and fogging removal potential are
adjusted
1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
When the value is decreased too much, drum ghost may occur.
