    Biz C454 demo page B & W ?

    This is first time I have ever seen this on any K/M. I'm looking to buy this C454 but wanted to make sure this issue is something simple like a setting,etc.

    Will copy in color, service mode test pages in color but demo page is B & W.
    Not sure about printing because it is in a lease return warehouse and I couldn't test that.

    Any help appreciated.

    Thanks in advance

    Utility -> User settings -> Printer settings -> PS Setting (and PCL Setting)

    If those are set to Grayscale that could be your culprit.

    Not to panic. It's probably just defaulted to monochrome.

    If it were me I would take the time to connect my laptop, and make sure it can print. Quite often, lease returns have the HDD wiped, and will need the animation data reloaded. =^..^=
    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.

    I had one do that too but don't know why. I didn't worry about it as the customer won't be printing the demo page anyway. That machine now has million prints without consequence.

    Thanks for the replies:

    Good to hear it shouldn't be a serious problem. I may bring my laptop in and try and print in color.

    wseyller, agree don't about demo page as long as it prints in color. Nice to hear it is a good model and running to 1 mil !

    Blackcat & speedtek. Looked at the printer settings and all other settings (for over an hour in front of machine and another hour in service manual). Nowhere to default to monochrome. I know you can do this for copying, and printing in the drivers but couldn't find anything for test pages in B&W only?

    Thanks again

    you could always have a nice color .PDF on a usb stick, if it can print from removable memory in system user box (usually pops up asking to print anyway) and its in color it may just be a dip switch making the test page mono. or corrupt firmware?

    Have a machine doing this too.

    For an unrelated reason I replaced the hard drive in the machine and noticed it was printing colour demo pages after it was set up again, but once I restored the authentication settings backed up to USB key prior to HDD replacement it returned to BW demo pages.

    No one cares, though its handy for techs to to do colour test prints without going into service mode or using a computer.

    What if you logged in with user auth first then enter user mode and print demo? Is public user set to only print mono

    The copier I had seen it on did have account track. Sound like auth may have something to do with it.
