    C458 ghosting/shadowing

    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.
    A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.

    Blessed are they who can laugh at themselves, for they shall never cease to be amused.

    Not original toner cause the issue.
