C458 ghosting/shadowing

[barber782]

Hi everyone,

Had a strange one today where a C458 is leaving a repeat or shadow of the image/text a few inches down the page.
Swapped the colour drums round and replaced the black drum with no different. Changed the colour of the back ground to cmyk to see if it did this on all colours and still did.
It almost looks like it's not discharging the drum. The gap between the text and shadow is about the same as the drums circumstance.
Any ideas would be appreciated.

Have you checked the transer unit and fusing unit for the image?
A photo would be nice

Cheat the door/WTB and see if discharge LEDs are working. If they fail you also may lose developer so check halftone patterns in service mode.

Aftermarket toner?

I just found this old post, try adjusting the primary transfer voltage :

Not original toner cause the issue.
