    What have you checked? Which direction are the lines...feed or crosswise? Please do not expect us to diagnose a fault without giving us a few clues.
    Please do not PM me without asking first.

    Have you done anything? =^..^=
    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.
