Clean precharge corotron, Developer HVPS and make adjustment with PWS.
Donor Voltage should be from 195 to 250, jump voltage should be bellow 2500
If it doesn't help replace developer material. If voltage is not in range change donor roll again.

Hello,

cleaned the precharge corotronand the HVPS several times but the problem
still exists. Next i will change developer and donor roll as you've suggested.

I will certainly report back.

Thank you for your helpful tips
