    Post Unused Taskalfa 250ci prints horizontal lines

    Hi!
    I bought a used Taskalfa 250ci few days ago, the office that sold it hadn't used it for about 6 months, the printer was working perfectly and regularly serviced.
    When I tested the printer I found that it prints repeating horizontal lines - yellow-black-magenta-cyan - - yellow-black-magenta-cyan.
    I assumed it was just dirty and would automatically clean itself with use, but it didn't.


    Do you have any advice on what the problem may be? I thought of a roller on which sediment has formed, but before taking the printer apart I wanted to ask someone more experienced than me.

    This is the scan of a blank print:

    We need to see some test prints of the problem you describe. Also, if they're repeating lines, you need to measure the distance between and tell us what that is. Thanks.

    What interval does the cyan mark repeat at? Try printing these images:

    A che intervallo si ripete il segno ciano? Prova a stampare queste immagini:

    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.

    This is with a blank print, where the lines are more visible:

    Lines are from OPC's. Cartridges are OK it is just bad printer. Did you try simple calibration?

    You still need to measure the distance between the repeating lines and tell us what that is. I'm guessing it's the drum but I'd rather not guess if at all possible.

    Each line is exactly 9.65cm from the previous or next line of the same color.
    Black <-9.65cm-> Black
    Magenta <-9.65cm-> Magenta
    etc.

    As I said, the printer was in perfect, it still unused for about 6 months (or more) and when we turned on it started giving this problem.
    Could it be sediment on the 4 drums?

    I think it's a drum problem
