KM-5530 Drum Issues

[586eddiem]

I have a KM 5530 that keeps putting physical lines in the drums after a few thousand copies. The blade and developer are good. Someone sugggested changing the Corona Charge Grid - Any other suggestions/ideas?

I agree with the person that told you about the Grid, the only other thing I can think of, is a possible Drum Blade, though I seriously doubt it, but it is cheap enough that you can change it also
