    [Jamming] Problem with jam from Roll Unit 2 on MP CW2201SP

    Hi!

    We don't have that much experience of the MP CW2201SP and we have a customer that has this unit and have alot of problems with it and most seem to be connected when printing from the second roll unit.

    My colleague who has seen the machine on site have noticed that after a successful print and when the paper is cut the printer rolls back the paper and when it rolls back it seems to have a tendency with the next print to get stuck in one of the "cracks" in the paper path.

    The most frequent Jam code is this one (from ARMS)

    11:08:06 JAM 54 Paper Jam Loc: Registration SN: Late(SP7-504-054)[Read Only]
    from SM
    54 A2 Paper out (Roll Unit 2)
    54 Roll end at Roll Unit 2. The roll unit exit sensor did not detect paper for 7 sec.

    We haven't been able to figure out if it's mechanical issue, paper issue or even a driver issue, when my colleague was on site this week we couldn't reproduce the problem of course, the customer is also located quite distant so we want to have as much hints as possible to not go there without having a good working theory.

    The customer itself has noticed it happens more frequently when the paper roll is near end that it has the tendency to curl up, so is it an idea to switch paper?

    The full error history is:

    we have only one of those expensive units around (luckily), I know little about it too, however, if I remember correctly, behind there is a sheet metal that can be removed, with a screw, and behind there is a sensor, it could to be cleaned (?), I am also sending you this bulletin, maybe it could be useful

      I sent my colleague to check it yesterday and apparently the second paper holder wasn't set in place correctly which seem to have been a cause for the j54-code.

        You gotta love the easy fixes, especially on this machine.
