    Re: c308 losing network connection, but only for scanning

    Scanning using hostname or ipaddress ? Should be using hard ipaddress that would address a DNS issue

    Did you reboot PC after you turned off sleep on Lan? Some setting changes required a reboot inorder to take.

    Try to change the Network Speed to 100Mbps Full Duplex. It's under Admin settings
    Network Settings --> Detail Settings -->Device Settings

    Re: c308 losing network connection, but only for scanning

    Hi,
    A case very similar to yours happened to me on a printer. The printer literally went offline every time a scan was performed.


    The solution was to change the network speed. Administrator Settings - Network - Network Speed. Instead of Auto 10/100/1Gbps I have set Auto 10/100Mbps

    Ok, changed it via remote web portal. I'll get someone on-site to power cycle the machine. Thanks.

    Well, no joy on forcing the copier LAN mode to 100M/full duplex. It failed again this afternoon.
    I guess I'll have to run the FW update, and go from there....

    That should have been the first move

    If I was on-site, it would have been. I'm over an hour away, and am waiting for parts for another job at the same site.
    When I go next week, I'll do both together. I'm limiting my in-house time right now due to COVID exposure risk.

    Re: c308 losing network connection, but only for scanning

    I'm not certain that it would have an effect, but it might be worth disabling SNMP protocols. On some of my older machines, they like to show as "offline" according to windows, despite the connection being fine. If you disable the SNMP, it's like the computer stops pestering the old copier with queries and just lets it get to work.

    Re: c308 losing network connection, but only for scanning

    So I'm gonna be on-site tomorrow to update the FW, and would like to set up the FTP on the server at the same time, if someone could provide some guidance on how that works.
    I've tried to find the Konica FTP utility, but all the results I find seem to be spam hits.
    Also, would I be better off using that one, or Filezilla? I don't know anything about either, so whichever you folks suggest and can explain more easily I guess would be best.
