Hi, i've a kyocera FS-3820n. Total page counter 91000. The prints are a little faded. I've check the developer and drum, for me are ok. In the manual service for prints unsharpness the possible causes are:
Unsharpness.
Causes
1. Defective paper specifications "set to normal for me"
2. Defective transfer roller installation "it's ok"
3. Defective transfer bias potentiale to check these value. Is out of range.
4. EcoPrint setting "set to off for me"
I can't check the high voltage unit- The default bias transfer roller is about -2.3 kV. My tester isn't able to check these value (out of range).
The prints are little faded with 300-600-1200FAST resolution. With 1200Fine resolution the prins are more faded.
Please help me. Thanks in advance. Stefano
