EPOTOFST
Manual entry of potential sensor offset
Lv.1 Details
To set the offset auto adjustment value of potential sensor manually.
As the value is changed by 1, offset value is increased/decreased by
1 V.
+: potential is identified as lower than the detected potential
-: potential is identified as higher than the detected potential
Use case
To restore the value to the factory adjustment when an error is
displayed (when the value out of specified range is set due to
potential sensor cut wire/connection failure/installation failure) on
OFST (auto offset adjustment) at the replacement of potential sensor.
1) To stop the error, set 0 (V) at EPOTOFST.
2) Check around the potential sensor.
If there is an issue, address it and if not, go to the step 3).
3) Enter the value of service label.
4) If fogging etc. occurs, increase the value by 10 V increment.
Adj/set/operate method Enter the setting value and press OK key.
Caution
Do not use this at normal service.

Lv.2 Details
To make a fine adjustment of developing contrast target potential that
is used at the potential control with D-max control OFF for quality
paper group only (display/adjustment).
Once D-max control is OFF, density is controlled only by the
environment table information. This can adjust the developing
contrast target potential manually to adjust the density.
As the greater value is set, the density gets high (as the value is
increased by 1, potential is increased by 1 V).
Use case
When D-max control is disabled for some reason.
Adj/set/operate method 1) Check that D-max control is OFF.
2) Enter the setting value and press OK key.
3) Execute the potential control manually.
4) Check the density of solid area in 17 gradations.
Display/adj/set range

Lv.2 Details
To make a fine adjustment of developing contrast target potential that
is used at the potential control with D-max control OFF for coated
paper group only (display/adjustment).
Once D-max control is OFF, density is controlled only by the
environment table information. This can adjust the developing
contrast target potential manually to adjust the density.
As the greater value is set, the density gets high (as the value is
