bizhub C500 PRO - Line in Magenta

[Guest]

Hi,

I am getting a line in magenta,
I replaced:
Magenta DRUM / Magenta Developer Unit / and Charge wires
and I still get the same line.
Can anyone help me and tell me what can be causing this??

Thank Everybody!!

pull your transfer belt and drums, then take canned air and blow out below the black plastic bar with the drum potential sensors . Probably a very small piece of lint hanging in the laser path to the drum. Don't forget to clean the laser windows to the right of the dev units.
