[CQ] Konica 7228 Giving Streaks and Background

[rbazan]

Konica 7228 was getting dark copy with streaks.
I cleaned all the parts around the drum out.
Checked and cleaned the Main Corona.
After I finished it got darker!


I think it's a Main Corona grid bias or developer bias problem.


I do not want to invest in a Drum and Developer unless I really need to.


Anyone know where to start testing.


You can see a sample of copy at

You'd better try to ask this question in Konica Minolta subforum, which can be found at http://www.copytechnet.com/forums/konica-minolta/
