    FN20 ISSUE

    Have a FN-20 fin. that when saddle stitching the papers dont line up the top sheet is off . We tried the same paer on a FN-24 and it works great. It also works on a MXM623 saddle stitch finisher. This a new unit. The paper is 11x17 28lb super smooth. Any ideas of what to try? Thanks

          Everybody I talked to at sharp thinks it is strictly a paper issue. The customer is changeing to a different paper.

              Did you ever fix this?
              I have one doing the same thing only on 11x17.

                  I modifiyed the crescent rollers
                  in the lower exit part of the finisher
                  by removing the rubber tire and adding a flapper ,

                  no problems yet
                  it seems to be a paper issue
                  I will post pics and part #s

                      the roller is in the bottom of the finisher at the saddle exit tray
                      you can remove the tape that covers the hole and open exit door with a pair of pliers
                      I removed the rubber tire
                      cut a slot in the hub and added the
                      flapper, I did trim the flapper down just enough to touch the paper
                      the paper that we are running it 28lb hammermill
                      as far as I can tell the rollers never touch
                      and I think it is a static issue
                      with the paper
                      this fixed the issue
                      part # for the flapper is 0cw4141p320// paddle

                                  Those adj. didn't help us. We ended up making new rollers as described above. Just went about it differently.

                                      Out of curiosity, where did this bulletin originate? First time I'm seeing this.
