    We have 2005 model Roland 702 in our print shop. Especially in papers up 200 gsm we have sheet travel problem. machine takes 5-10 paper than stops. then 10-20 and stops again.
    At the same time in Screen in always shows that -10/-10.

    AEP->nul.(preset, feeder) and check again. If same, position the feeder at 180 degrees.

    thanks a lot. We solve the problem with both side coated 270 gsm but we still can not run the machine for 350gsm paper (foto in attacht). The machine take 1 paper than stop. In every start takes only 1 paper and then stops.

    You have not solved any problem. R700 works normally with 7-800 g/m2 material. I think you need a printer.

    We already print with 500-600 g/m2 without any problem. Our problem starts if we use one side Kraft paper ( as in the upper picture ).

    With one side Kraft paper we can`t run the machine continuously. In both side coated or white paper no problem in any g/m2 at all.

    Could it be that the print sensor doesn`t see the kraft side of the paper?

    It would be the same with 100g/m2. kraft.
    If 100g/m2 does not work either, then the problem is in the sensors.
    So far (30 years) I have not had such a problem with kraft.

    Try moving the material forward using timing.

    PP You can also try the sensors with kraft on the open lid. Change the small / large format of the sensors.
