DPOT-K Display of Bk Drum surface potential
Lv.1 Details To display the current surface potential Vd on the Bk Photosensitive
Drum that is specified as a result of the potential control.
The value after the calculation of potential offset is displayed.
If the offset value is not adjusted, negative value may be detected
during printing.
Use case When the density failure or foggy image occurs, check whether the
surface potential of the Drum is the factor.
Adj/set/operate method N/A (Display only)
Caution - To update the display, be sure to move to a different screen, and
then move back to display it again. (The potential at the moment of
showing this screen is displayed.)
- If the value is out of range (-30 to 30), there is a possibility of
Potential Sensor disconnection.
Display/adj/set range -30 to 600
