    [Jamming] KM 5050 Image shifted & line appears on paper

    Hi guys,

    Last few days I was cleaning my machine. I pulled out drum, charger etc, lubricated some gears, removed "Registration clutch (RCL)".
    After I put them back machine started printing wrong. The image is moved up or left depending how my paper is positioned in cassette and a line appears on the paper.
    If I put more pages to print on cassette 1 machine gets a paper jam , cassette 2 doesn't get jam.
    I can't figure out what is the problem. Drum looks ok and I did a refresh.

      I tried the U034 LSU OUT LEFT but nothing happens. I noticed that the amount of image displacement is changing. Sometimes goes a little bit left sometimes a lot.

          Is it feeding portrait or landscape? Have you checked/cleaned Registration Roller?

          Also, check settings in paper cassette tray.

              I'd say reg.sensor or reg. clutch badly assembled. (Have you 40-it with Wicious Delicious or used just IPA)

              The first image is Lanscape and the second is Portrait am I right? You have a delay on paper transport and I think the clutch will be worth looking at. Check for the feed unit being properly installed. Is it within the slide? Are the gears mounts OK? I had one feed unit which had cracked casing (the nipps for the slider) and it was doing the same. Option two the sliders can be cracked or broken when feed unit is forced or incorrectly inserted and doors are after slammed. Those slides are fun to replace. Good Luck

              Let us know how did it go.

                  How was it printing/copying
                  before you took it apart?

                      Naturally, if it was working OK before you started, you can be sure you caused the problem. Start by re-examining the things you did. WD-40 is a horrible thing for copiers (with the exception of cleaning metal only components, or rubber rollers). Plastic parts melt.

                      My suggestion is to get the WD-40 out of your bag. If you damaged the registration clutch, don't bother damaging it more by sanding the plates. Just replace the registration clutch ... and learn from the experience. =^..^=
                      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.

                          Well I didn't use WD40. Reg clutch was a bit rusty so I cleaned it with cotton sticks and a bit of oil which is non-conducting oil . I checked it and it works but can't tell if it is to weak or something. May be badly assembled(have to check). I also pulled out white reg.roler but you can't do a mistake there (I think)
                          Where is the reg.sensor positioned? Somehow I didn't notice any sensors back there.
                          Habik i think a delay problem is very good assumption but problem is to find what caused it. If the feed unit plastic was damaged wouldn't it jam on cassette 2 also? Atm cassette 2 works fine transferring the paper but the delay is also present. Cassette 1 goes much faster and then machine stops (jams code) cos the paper comes into feed in wrong timing?

                          Also is it possible that I put to much lubricating grease on that group of gears that reg.clutch is part of ?

                              Can you explain exactly what is the role of reg.clutch? How will I know the clutch is damaged? Cos for now it clicks

                                  The registration clutch ( along with the registration sensor ) aligns the lead edge of the image with the lead edge of the paper.

                                  You can tell if it's damaged by testing the machine with a new clutch to see if it solves your problem.

                                      Oil is a bad thing for electromagnetic clutches. Oil makes them slip. You would be better served by cleaning with alcohol. As their name implies, electromagnetic clutches use magnetism to engage the drive, and the best results are achieved when the clutch plates are dry, and clean, and smooth as possible. Sanding makes them rougher. Don't sand or buff. Just wash with alcohol. =^..^=

                                          Re: KM 5050 Image shifted & line appears on paper

                                          Hey guys,

                                          There are two 302GR44140 2GR44140 CLUTCH REGISTRATION and I did clean both of them .

                                          So I disassembled and checked if I put something wrong, assembled them but did a little trick.
                                          Cos I can't get my hands on new clutch in short time to test, I switched them to see if the error will pop out on another position.

                                          Machine works fine for now. Maybe it was a bit of oil residue in them or they lost some power(cos they are old), bad assemble...
                                          I have to get at least one new clutch to have in stock if the error comes back.

                                          Guys your suggestion and support was crucial to my success. Thank you
