    Bizhub C652 is permanent disconnected

    Hi

    Our Bizhub C652 is not connected, but are available on web browser by IP.
    If we print a page, select repair printer, the job is printed out, and then it becomes disconnected again.
    Sometimes we get message on the C652; "Unable to connect to auth. device."

    Any solutions on that?

    disable the auth. device.?
    remove the loadable driver.
    using the correct driver and not that universal garbage driver?
    make sure account/copytrac and authentication are off in admin mode.
    make sure account/copytrac and authentication are off in the driver defaults

    if you cant find any of these settings, find and select 'print without authentication'
    i mean you kinda answered your own problem with the question.

    I have the driver from Konica; C652SeriesPCL.
    Admin on browser says on "Restrict User Access" Allow on all 3 available selections.
    On C652:
    Admin->User auth/tracking->General->User auth = OFF
    Admin->User auth/tracking->General->User tracking = OFF

    When I open the print dialog and selects User auth/tracking, the C652 alerts "Unable to connect to auth. device" on the screen.
    Still no luck

    Have you got any Authentication Device installed on the machine like USB card Reader or something else?
    I thing it is setting the Authentication Device on the MFP.
    Try the Service menu and Stop->9 and Management Function Chioces and set off any type of authentication (Card1,Card2,Bio1,Bio2)

    If you bought this used it may be in CAC/PIV mode..This is a form of authentication that can't be easliy removed. Usually seen in US government applications..Especially with the "unable to connect to authentication device" message. Post the firmware version and we can tell you if it's cac/piv. E

    When I open Management Function Choises, it says UNSET in top left corner. I have checked all items below this level, and could not see any selections that was enabled.

    We have had this machine for 6 years. We bought a Xerox C570 some weeks ago (that also does not work) and maybe the problem with the Konica happened when we installed the drivers for Xerox. We have deleted all drivers for Xerox just in case, but no luck.

    Please try to initialize to clear the network card from service mode. if it doesnt work, you maybe need to change mfp board.

    Could not find that alternative.
    But if network card wasn't OK, should we be able to open webbrowser, type in IP and everything is available then?

    We are able to print smaller things when we run "repair printer". When print spooler is restarting, the printer receive the job. If larger jobs, the file does not have enough time to send.
