Dear all,
Do anyone face no solid on this model? Currrently i have 1 unit with over 7million total count and can't perform solid black on print.
The printout shown all shadow area got white patch/dots. I had changed primary corona wire,transfer/separation wires, drum unit, developing unit with new toner cartridge.
When changed,it able to print solid black but issue back after print more.
Any suggestions on this matter?
