    Black copy with TA-520i

    Hi all,
    I have black copy and prints with TA-520i. The problem is not all time. It's random problem. I check main charge and all HV contacts. I need a solution please. Thx.

    It's going to be something related to primary charge. How about replacing the primary charge unit, and if it returns HVT? =^..^=
    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.

    I didn't replace them, but I sow something wrong on the Power suply board. the big capacitor does not value it should. Do you think it's can make this problem? I will change it.

    Check the grounding tabs to the transfer roller on the left side door. If they are bent you can get strange black bands sometimes covering the entire page.

    unplug cleaning motor from corona charger, remove grid by removing one screw, take off small metalic shaped wire, most of the time making bad contact with charger unit. Put back grid and leave unpluged cleaning motor.

    Re: Black copy with TA-520i

    I was wondering if this problem came back after you replaced the MC Corona.
    A colleague of mine had exactly the same issue when he did a PM. Then he put the old MC Corona back and the problem went away.
    The problem just came back and the call got assigned to me. Before heading out there thought to check the forum.

    Thanks!
