Greetings to the whole community and thank you very much in advance. It turns out I've been having quality problems with the Magenta unit for a few weeks. As you can see in the 2 photos attached, I get some magenta stripes in the background and the same background. I cleaned the transfer belt and disassembled the Magenta unit and cleaned the crown, cleaning sheet and drum. When assembling and retesting I have noticed that it even worsens. I do not know where I have read and if it is true, that this unit has a little screw which sets the height of the crown and should not be touched. As much as I look, I can't find this little screw and there is no way to correct those stripes. If you could help me, I would be very grateful Thank you IMG_1481.JPG [52.53kb] [url=/ver-adjunto/aHR0cHM6Ly9jZG4ueW9yZXBhcm8uY29tL3VwbG9hZHMvZGVmYXVsdC8wMDAxLzkwL0lNR18xNDgwLTM4NDQ5LkpQRw==] [img] / gp./gt./gl_gng/glu/g1_gng/glu/g1_gng/g1

Dear: I enclose a few YouTube links where you can appreciate in detail the remanufacturing of the imaging unit: there is a grid that is above the crown and facing the OPC, observe, it has to be very clean, lint-free and well stretched, it does not have to be undulated, it has a fixed clip at one end and another retractable at the other end , the failure of a vertical background in the leaf, broadly encompassing and undefined as the one I see in the attached image may be caused by this grid, and the crown ends are usually burned, it is a very particular, insulating material, they burn and they start producing your fault and continue to increase until a total background forms on the printed sheet, to know if it is burned, it will seem very primitive but I smell the material and if I perceive the smell of burnt electrical material, we are in trouble. I await your comment, best regards
