    Repeating Image

    We have a customer with a Bizhub C353 which is repeating images on ledger paper. If I copy a letter original onto ledger paper, the image is repeated starting about seven inches from the lead edge. All four colors are effected, so it's not a single I.U. If I set paper type for thick 1, it doesn't repeat, so I suspected the fuser, but a new fuser didn't fix it. I tried changing transfer settings in both directions, and tried turning fuser temps up and down, with no result. Anyone seen this before?

    Whats the life left on the transfer belt? I just had this happen last week on a C353 as well. It needed a new belt.

      Belt is pretty new, but that doesn't mean it can't fail. Thanks for the reply. I will try it this morning and follow up.

        The problem is not your belt.

        Your first clue would be the fuser, since you admitted to setting to thick 1 and the problem went away.

        Are you printing to thick paper? Anything heavier than 24lb should be set to one of the 4 available thick settings (bypass tray) or 3 thick settings on all other trays.

        Plain paper = 15 - 24lb
        Thick 1 = 24 - 40lb
        Thick 2 = 41 - 55lb
        Thick 3 = 56 - 68lb
        Thick 4 = 69 - 80lb

        Keep in mind that the machine should give an abnormal low C-code if the fuser was at fault.

            I'd be inclined to agree with Stirton.M! 7inches from lead edge till start of offset image? Thats WAY too short a pitch for one of those transfer belts!! I'd be heading for the fuser too!

            Regards!

            Oh yes, as a side note, I've seen dirty print on a linen bond that felt like 20 odd pound paper but wouldnt run clean unless it was set @ thick 1. (c352 series tho) On plain paper.. clean print... the linen stuff.. not so much!

              Do single sided copies if your repeated image is on the back side its your fuser otherwise its your belt hope that helps. Make sure right settings are set for the paper tho thick 1 etc first.

                You won't believe this. I couldn't, but the transfer roller fixed the problem. Not sure why, yet, but if I figure it out, I'll let you know.

                          Replacing the 2nd transfer roller would change pressue and bias that is being applied to the belt. Was the ghost image from the same page, or could it have been from the previous page? In which case the distance would be in spec for the belt as indiacated earlier. If problem returns.... Replace the belt.

                            The ghost image was from the same page. It's been almost a week and no callback.

                              Heres a twist, i just got a call on friday of last week for a c353 doing what sounds like the exact same issue as the the thread opener here! I'm going in today to have a look-see, and brought both a 2nd xfer roller and a fuser with me, the customer can replicate it faithfully too. So since the second xfer resolved it here, I'll try that first and post the results here. I've seen second transfer do weird things before but nothing quite like fuser type offset images! We shall see. to be continued!
