    CS-3010i intermitent black lines when printng or copying

    Hi,
    i have this problem with 2- CS-3010i and 1- CS-3510i all installed on different offices/customers

    Problem:
    Intermittent black lines across pages, perpendicular to the page movement. (see the attachments) it can print fine for a few hundred pages or show the problem few times a day.

    already replaced:
    Drum Unit, Developer unit, bias voltage board, reconnected connectors on boards.

    The cs-3510i started showing the problem when it was almost new. i had to replace all 3 machines and now i have them in my warehouse.

    That looks like a laser failure, to me. =^..^=
    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.

    same problem whit utax 3060 and utax 2540
    there are false contacts between the connectors main charge, drum dv unit and those in the main body

    Could you explain the steps to resolve the false contacts?... since the contacts have springs and i already stretched them but the problem persist...

    Thanks in advance!

    yes you pulled the springs out BUT are they making the proper contact with the units?

    were the drum/dev units you replaced NEW or were they pulls from another machine?

    did you init them in service mode?

    have you cleaned the laser glass? BC mentioned the laser have you tested that?

    [QUOTE = mad; 1733318] Potresti spiegare i passaggi per risolvere i falsi contatti? ... visto che i contatti hanno molle e li ho giÓ allungati ma il problema persiste ...

    Grazie in anticipo! [/ QUOTE]
    you must also deoxidize these well and check that the groups remain firmly pressed and also check the connectors that go on the hvt

    excuse me for my bad english

    Thanks for you reply Phil B

    new developer and drum,
    the laser is clean and working as shows the enlarged image (the text can be seen "behind" the black line (green arrow)
    the lack of a white margin (red arrow) tells me is a problem with the developer bias voltage or maybe a drum ground problem...


    the path of the Developer bias voltage has many "steps" and a 3 or more springs to get to the magnetic roller.
    each one of this "steps" is a possible false contact. and the springs are difficult to handle because their location.

    i was hopping that someone had figured out...

    I see the image behind the bars crossfeed. I agree that it's probably not the laser. Probably a high voltage, either developing bias or primary charge. The HVT (high voltage PWB) seems like the next logical choice.

    Vedo l'immagine dietro le sbarre crossfeed. Sono d'accordo che probabilmente non Ŕ il laser. Probabilmente un alto voltaggio, che sviluppa polarizzazione o carica primaria. L'HVT (PWB ad alta tensione) sembra la prossima scelta logica.

    Are black lines repeted at same distances. If yes from these distances you can find what cylinder (drum, chatge etc) it causes it (the perimeter is equal to distance).
