Greetings,
I have situation with black copies and prints coming out with text.
I have changed all corona wires, after that complete primary assy, cleaned complete developing assy together with the drum unit and potential sensor, checked back side of transfer separation ground wiring, but the copies still come black.
I have the following reading in Service mode>Copier>Display>DPOT:
DPOT-K 0 V; VL1T 70 V; VL1M 2 V; VDT 390 V; VDM 2 V;
VG-K 592 V; VL1M-P 2V; VL1T-P 70V;
VDM-P 2 V; VDT-P 390 V;
BIAS-P -(minus)167, BIAS-C -(minus)167;
LPOWER-P 128; LPOWER-C 128
VDT-S 260V; VDM-S 2V
When I turned off Potential Control (Option>Body>PO-CNT from 1 to 0), the print seems good.
Every help will be appriciated.
