Prints and copies are both not very good. The yellow and magenta, do not show up at all and the cyan and black are very faint.
I have replaced the drum/dev/toner unit for all four sets. Issue still very prevalent. I ran an auto gradation test a couple of times. NG. Cleaned the lasers in the frame. Nothing is making the issue better. is there anything else I could do to correct the issue?
