EPC-VL1
Dspl of potential VL1 at potential cntrl
Lv.1 Details
Displaying light area potential VL1 at the time of laser output (50H)
that is measured by potential control.
In normal status, it will be VL4<VL3<VL2<VL1<500 (V).
In abnormal status, this can identify an assumed cause from
potentail sensor, drum and charging assembly.
Use case
When the image density is out of the reference, check if there is fault
in potential control.
Adj/set/operate method N/A (display only)
Display/adjust/set range 0 to 600

EPC-VL2
Dspl of potential VL2 at potential cntrl
Lv.1 Details
Displaying light area potential VL2 at the time of laser output (90H)
that is measured by potential control.
In normal status, it will be VL4<VL3<VL2<VL1<500 (V).
In abnormal status, this can identify an assumed cause from
potentail sensor, drum and charging assembly.

Dspl of potential VL3 at potential cntrl
Lv.1 Details
Displaying light area potential VL2 at the time of laser output (C0H)
that is measured by potential control.
In normal status, it will be VL4<VL3<VL2<VL1<500 (V).
