97699768:confused: I need help. I am printing booklets and get lines all over pages specially on pictures.

When print single colors I get lines on yellow and Cyan. I cleaned the Corona wires, the sensors, I switch a developer unit from another machine, switch drums and coronas and didn't help. Please look at the images i uploaded, If you have any sugestions to help isolate this problem please let me know. Cheers.

Hi there!
I think the Magenta-imaging-unit is gone. You should try another one ( if possible).Make printouts "halftone-pattern" with a value of ca. 125. Then you should see which unit(s) cause the problem.

Replace units or clean corona wires(it easier if u dont have other units) then try to replace PH places to see is there any change on image (eg. exchange cyan and magenta PH)

Which toner are you using and when did you replaced toner? Also tell me if the toner is scattering around drum and dev. unit especially Magenta.

Had this type of fault many times, It is always ether carona assy or dev. I would change the carona assy as a whole part 1st.
