Hello,
After putting new main corona , I got some vertical gray lines on paper (light gray) and the toner yield is about 20k-30k A4.
We doubted the drum, but after swap, the drum was not the problem. If we turn off potential (swapped also), I have no problem with quality, but toner yield is about 20k.
What could it be, please?
Thank you
