    I've seen this caused by the double gear assembly at the plate cylinder. There was a time that I'd heard Heidelberg was not putting in the needed zerk (fitting) to achieve greasing, but I have not seen a machine without it. It would be to your benefit to look at the face of the inner gear (under the drop down cover on gear side) and search for a greasing point. I have worked with many who are experiencing the same problem, and the steps I described have resolved the image movement issue. I hope this is your solution also! Good Luck

    Yeah but if Heidelberg themselves can't figure this out within numerous visits, they should close the gate, go home and never come back :)
    Especially that their headquarters are probably few hours drive from Slovakia.

    Yes Heidelberg servis registered office is 900 kilometers to find a company but that does not excuse them! Boss wants to return the machine is very furious.

    It seems that the machine was manufactured in Afrika desert :)

    And we have other biger problem with washing-all unit griper splashing after clean automaticaly blanket and cilinder look like 20 yers old mashine-realy!

    And after 1 year burned main engine for Feeder and Delivery

    Wow, looks like you have yourself a lemon, so much for having a Heidelberg headquarters next door - so to speak.
    You really should make your best effort to have it replaced. I wonder how many guys went to Ryobi / KBA / Komori reading this post :) and how many will...

    Heidelberg servis come with own plates made in Germany, same mark as we use- KODAK.

    Mashine was testet 2 days,All gripers was cleaned,all blanket+packing was full new, paper 135 gms matt and gloss

    The press room temperature and humidity is controlled we have air conditioning+special system for humidification who working nonstop 24 h.

    After test Heidelberg he says it's a problem in the machine somewhere.

    Somewhere?Company with 100 years experience dont know where is problem?.I think so must know very good.

    Are all units moving? After makeready and running for a while, does it settle down? Is the problem mainly at the beginning of the job? If you stop machine, or it trips off, is the problem worse once you restart it?

    I believe junker hit the spot with the gears, if there is not grease in them, they can begin to get slack and wear, that would create your up/down issues on all the units. I have seen that before on other presses myself. if they go ungreased long enough, you may have to change out gears as I did. not a fun job I might say.

    Hi,

    some twenty years ago a used web were installed in our comp by manroland. After several weeks of installationworks the collector unit didĒ¹t work proper. Tons of paper were in trash. Solution: they used a highspeed camera to watch and locate the problem. Perfect!!

    Hi Printerscd - I'll have to ask my Dad if his parents ever mentioned what city they were from. I worked for Heidelberg 15 years, been working on my own the last 15.

    Shall I suggest you something? This may sound silly, but worth a try,

    you have this problem in all units or just a one unit?
    however, just disconnect the register motor wires (circumf. and lateral) after you've register the job and then monitor.
    at lease we can then distinguish the fault coming from the electronics or mechanical.

    others ideas about this is also appreciated.. :)
    cheers

    HI

    Last Week was Heidelberg servis, 4 mechanics try fixd problem with moved register...

    They Check all 8 units gripers-clean set up.... cam flowers.... so all mashine

    Yesterday was make SID test and register moved so much like always almost 2 years

    After test Heidelberg evaluate so problem is in plate clamp ok but this is realy funny because was put in 3 times new plate clamp and now is strongest but Germany Heidelberg talk so Servis of Slowakia Heidelberg first time bad put and setup plate clamp because problem is from first day if mashine start runing.

    If i setup register on makeready after 500 sheets move register, optimalization is after cca 5000 to 7000 sheets

    it is possible that the problem is in plate clamp ?

    Thanks

    Not very likely, but you know once you're at this point you have to follow the direction Heidelberg factory is taking you, meaning let them troubleshoot as they see fit. Cleaning grippers? If the sheet was moving due to poor transfer elements, you would see double imaging or slur. You've never mentioned that issue. If it's simply having to repeatedly adjust register after start up until you've re-achieved your makeready positioning, it sure seems to me it would have to be unstable clamps (after 3 attempts to repair by Heidelberg, I'd think that's not the issue), or an unstable plate cylinder. Has anyone examined the plate cylinder elements we've discussed previously?
