    Re: Work centre 7830 blank display and all lights on

    No need to altboot after replacing SD card. chances are SD card is corrupt instead of faulty so can be re-imaged.

    PM me your email and i'll send you SD card image for this machine and win32 disk imager, you may need something like minitool partition wizard (free) to format the card first to make it readable by windows. Wouldn't hurt to have a spare card though, 4GB or 8GB will be fine.

    Thank you everyone for your help. I mentioned to the customer that the code pointed to the SD card.
    So he ordered one from xerox and installed it and that fixed it.
    I was really hoping to have to download the firmware just for the experience. But the machine is up and
    running and I still get to bill them for a couple of hours.

    Richard.xerox looks like I am going to service this machine so you are right it would be handy to be
    able to deal with this kind of stuff.

    Thanks again everyone, nice to know that I'm not alone.

    DR

    Re: Work centre 7830 blank display and all lights on

    I saw this machine the other day to get meter readings and to check the copy.
    The copy is good.
    It does display this message, "Immediate job over write failed, perform an on demand over write immediately"
    Then it gives the IP address.
    I',m guessing it has something to do with not storing jobs on the HDD.
    Does it need a firmware upgrade?

    Thanks

    DR

    Check in administation mode/tools/security settings for image overwrite option.
    If option missing, altboot machine.

    Since DR got his machine fixed ( different model than yours ) you should have started a NEW thread of your own.. now it will be mixed in with the 7830.

    please review all forum rules.

    giving a break since this was your first post.

    also please do not unearth a thread that was closed two or more years ago.

    You have to buy sd card from xerox.
    First try altboot
    Hi guys,
    I'm pretty sure that the fault is the SD card. Replaced them four times last summer due to thunderstorm power outages.
    The original card will help for sure but there is another solution. Re-program the card.
    Of course one has to get the 4G sized image first.

    When plugged in onto the ESS card the machine overwrites the serial number on the new card and it is gone = take a bit copy of the card in Linux or by some other means, you can always use the clone for re-programming the card.

    THEN use AltBoot and load the software.

    Good luck.
