    Re: Calibration marks on prints TA5052ci (Utax 5006ci)

    Hi.
    Which Hi Voltage board did you replace.
    High Voltage Transfer SP
    Or
    High Voltage Main SP

    Whichever one you changed, I’d replace the other before an engine board…just a thought.

    All is ok but it still happens, not every print but often enough.

    Anyone had this before? or know of a fix??

    nothing in the bulletins or firmware (but we did load the latest just in case)

    Regards

    As an update/reply,

    The latest firmware was applied and didnt fix the issue

    The new high voltage board did not fix the issue.

    All connectors are good and a new transfer belt was fitted

    We are now going to go back with an Engine board.
    Did the engine board resolve the issue?

    Tried a belt, transfer HV PWB and Engine PWB on a 3252ci, and didn't resolve it. Anyone fix theirs ?
    Hope that helps !

    Did you try the shutters I mentioned in a previous comment? Had this same issue on the same model yesterday and shutters were the issue.

    I did clean the ID sensors, but I did not reseat the connector.
    Hope that helps !

    If you have trouble with ID sensors you must get C7601 or C7602.
    Visible on event log only. (similar to C761x and C7620)

    Cleaned and reseated the ID sensors and then replaced the unit and it's still not cleaning.
    Picking it up tomorrow to continue troubleshooting it in our office.
    Hope that helps !

    Re: Calibration marks on prints TA5052ci (Utax 5006ci)

    I had this exact same problem. I replaced transfer belt, the little transfer connect PCB located in the front, and HV PCB.

    You may have already checked this but thought I mention anyway.

    Calibration Marks not being cleaned off the belt in time for a clean print job.

    The problem ended up being the black spring-loaded high voltage housing. The long STRAIGHT part of the contact springs were out of its track (not tucked in properly inside the little tabs of the housing). I couldn't recognize the problem until I fully removed this part from the machine. see pic. Check all spring contacts for deformity.
