    [Misc] BP70C65 tearing primary belts

    Hey all,

    Just wondering if anyone has been experiencing this in the field.

    I have a client with a BP70C65. The device has just clicked over 500,000 clicks so it gets a workout. Device has been out in the field for the last 7 months

    98% of there work is B&W A5 booklets so most of the work goes through short edge feed

    I have replaced a number of primary belts on this device as it keeps on tearing them and the belt runs through the fuser and into the paper pass unit before it registers a jam

    Anyone else having this issue out there. I don't know if it has something to do with the workload or the amount of impressions they are doing on a monthly basis, but it's getting a little frustrating now as to why it rips all the time.

    Interesting. I had a BP-70C65 have a messed up primary transfer belt at 40K but it didn't tear. When I took it apart there didn't seem to be anything wrong with the roller that would cause the problem. I replaced the entire unit. Did you replace the entire belt or just rebuild it? I have seen 2 or 3 tech bulletins regarding the belt. Sorry don't have access to them at the moment.

    Good luck.

      I have replaced an entire unit once which hasn't resolved the issue

      It's got something to do with the workload

      As stated, majority of the work is A5 booklets and I know there was a firmware fix where they added belt lubrication process during a run but it hasn't helped

        Here in Belgium there are no tech bulletins available regarding the belt, I just checked the sharpone website to check. Is it possible to send de 2-3 bulletins regarding this.

        Thanks in advance!
