    Bizhub C280 - Duplex pages folder in corner

    Hi folks,

    When copying to A4 duplex on my C280, the corner of some pages (~50%) come out with a small fold in the bottom left corner (image attached).
    The source paper is definitely fold free and standard one sided prints come out perfectly, as does A3 duplex prints.

    Is it possible to remove the duplex unit to see if anything is wrong, or any other suggestions of what might be causing and on how to resolve this?
    I'm not familiar with taking this particular printer apart (or which section to start on), but have no issue doing so if someone can point me in the right direction.

    Cheers!

    I used to add some spacers so the section right under the registration roller was raised slightly

      Yep, same here. In fact I checked all machines of that series we had to make sure they had spacers to prevent issue.
      Started in the copier service business in the fall of 1988 and worked at the same company for 33.5 years, becoming the senior tech in 2004 but left to pursue another career on 4/29/22.

        Thanks! I'm not sure where the 'registration roller' is...
        Would you be able to give me some pointers to where it's located and where the spacer should be added exactly?
        Also, what should I use as a spacer?

        Cheers!

          When you open the right side door you will see a black rubber roller that is about 14" long. Underneath that roller there is a guide that can pivot upwards. On each end of that guide there is a protrusion that contacts the machine. On the plastic under each protrusion adhere a small spacer. It doesn't have to be very thick.

              I used some single sided sticky pads which worked perfectly!

              As always, thanks so much for your help everyone - Hugely appreciated!

              Cheers
