    Kyocera 8052 trailing edge skew

    I've got two machines similar volume both skew at trail edge A3.

    MPT tray appears to be straight.

    I thought it was only the top two trays but every tray including the MP Tray skews by about 4mm from one corner to the other. lead edge enters fuser straight but drifts at trailing edge.

    I had to replace the fuser as the customer wrecked the rollers with finger nails. They've never noticed the skew on both machines but as the new fuser is new the skew causes it to add creases into the paper sometimes on A3 looks like Tiger stripes.

    I was thinking of replacing the registration and feed unit. The parts manual doesn't contain a whole registration part no. Is it possible the fuser exit or door is causing it to skew?

    Theres U061 Fuser loop but got not sure what to adjust or how?

    Any ideas bit bonkers.

      I would make sure that the door latched properly at the front and at the back. I'd check that the transfer roller is pressing up to the primary transfer belt, and has spring tension at both ends. And I'd take a close look at the registration rollers, to be sure you're getting adequate pressure at the front and rear.

      Uneven pressure in the fuser could cause the paper to turn ... even if the registration rollers were gripping the paper adequately.

      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.

          I just checked the prints again and the mpt tray is skewed just its less obvious... about 4mm of skew between bottom right to bottom left.

          Why would it drift on trailing edge? When I first put the fuser in I was getting them strange like tiger stripe patterns in the first image that seem to go once I ran plenty through.

              Enters fuser straight then drifts. Sometimes get a lovely crease but those seem to not happen with the old fuser unit but it still skews regardless old or new fuser unit.

                  Some of the earlier Kyoceras (FalconI/II/III) had shim adjustments for the fuser mounting position, for exactly this condition. I'm not sure if your machine has that adjustment. =^..^=

                      Please tell me you have something on that ? Totally stuck.

                      On the left side of the fuser on the machine it did have 3 lovely painted red screws and gauge at the bottom but had no idea what it did.

                      That's a 6052 the 8052 looks very similar. Has anyone adjusted that on the 80 page machine?

                          That's it right there. If there isn't one already, I'd make a paint mark at current setting, before making any changes. I'm encouraged that this adjustment looks very much like the FalconIII adjuster.

                          Go for it! =^..^=

                              Dont suppose anyone has the paper number for the fuser mount jig do they on these machines? Mine looks identical to that but i think that's an older model.

                                  The way that page reads, there isn't any jig, just adjusting the ramp in or out to raise or lower the one side of the fuser. Again, I would make a paint or scratch mark at your starting point to base your adjustments on.

                                      Re: Kyocera 8052 trailing edge skew

                                      Hopefully might help other people.. I tried the jig maybe moves the image 1mm if that so barely makes a difference.

                                      I was getting creases and for me what fixed that was the two fuser guides that sit underneath the fuser. The large brass coloured guide was at the wrong angle moved the old guide to the new fuser and it cured it.

                                      It has a slight skew image wise but I have a feeling its related to the laser but I'm still learning on this machine so I'll leave that for now till I learn more.

                                      Many thanks for the help.
