Xerox workcenter 5020 white lines printout

[rapo_tech]

Hello

Going on site 03. march, but would like to hear opinions for the problem Mainly repairing Kyocera machines, so Xerox is not so familiar.

Printer using OEM parts and toner.
A year ago replaced drum. Drum life is 22k and I'm sure they have printed 10k or less in that time.

Added sample of skyshot. Printed out long edge first.

So I'm thinking that maybe corona wire is dirty.. If laser glass would be dirty, then there would be more precise lines?
Or maybe theres some clogging in developer? Is there any developer refresh function? Should I shake/bang developer assy (drum)?

Before checking any consumable , primarily check the paper feeding unit and paper for moisture, and also for fuser upper roller for any damage, if all are good , check for grid toner contamination .

Corona wire was contaminated with toner.
Cleaned it and everything is fine
