    Question c308 losing network connection, but only for scanning

    Hi all,
    I've searched until my eyes are crossed, but I can't seem to track this one down.
    Also, I've investigated the possibility of it being an issue with SMBv1, but it appears that it's already on on this machine.
    The 'server' at my office is just a windows 7 desktop machine, acting as a file hub for our office.
    The Konica is set up scan to a shared folder on the server, and normally it works just fine.
    However, intermittently, it loses the connection to the scan folder. Sometimes it drops twice a day, sometimes it works fine for several days.
    When it fails, there is an error on the screen, but the office manager can't recall what it is exactly. I'll try to get a photo the next time it happens.
    Oddly, it will sometimes drop in the middle of a multi-page scan job. Rebooting the server fixes it for a while.
    Any idea what this could be?

    At what FW version is your machine?

    Have you replaced the network cable and changed the port on the network switch?

    Good question. Is that info viewable via the web interface?
    I'm remote at the moment.
    Also, I've just discovered that it seems that someone has changed the admin login from the default 1-8x2.
    Any idea how to reset it, or if that's even possible remotely?
    The plot thickens...

    Unfortunately, that's not an option. Someone (not me!) ran cat5 directly from the server area to the copier room. There are terminated cables hanging out of the wall at both ends. No patch cords, no way to swap them out. Yeah, I know.
    As for the switch, we haven't tried another port specifically, but the switch itself was replaced about a year ago. The issue existed before then, so I'm gonna say that's not the problem...maybe.

    Make sure the windows 7 box does not go into energy saver or turns off the hard drive

    Is box using Hostname or static Ipaddress it's not the copier it's the PC that is the issue

    I would do a continuous ping and note if there's any difference in the time or if it's losing connection intermittently.

    This sound like your Win 7 PC/server is possibly going into sleep mode then the LAN card will disconnect.

    By the way, I stole that from another member and I'd give them credit if I could remember who it was.

    Why would anyone change Admin password on your machine? That really doesn't make sense.
    You can reset it via service mode but that's another story.
