    Re: HP Laser Jet M880 fuser error

    I don't know how much this will help as it is from the M600 manual, but that says a 50.4X.YZ error means the machine has detected an over temp issue in the fuser (for what it is worth, the manual helpfully further explains only that "X"= the fuser mode, "Y"=previous printer sleep state, and "Z"=next printer sleep state, but not which each of those means exactly).
    If you've ever worked on old Canon fax machines, that experience can be helpful with HP equipment. I mean, I apologize if you've already done this, but you should turn the machine off and unplug it for a while (I don't know, get a cup of coffee or something, that usually works for me, although it could need to be unplugged for around ten minutes so take your time if possible). And maybe check the outlet the machine is plugged into to make sure it's up to spec.
    Anyway, back to the manual, such as it is. It says if the fuser is OK then to check the connector for the fuser for damage or not being plugged in correctly, and then replace the low voltage power supply.
    Also for what it is worth, here's something I found on HP's support website that might be more helpful than me:

    Thanks for your input Gentlemen, problem now solved.
    It appears that something went short circuit in the fuser and took out the 240v board that controls the fuser.
    Fortunately I had access to another M880 that I could use as a test box. Now I just have to wait for a new fuser to come off back order.

    p.s. please don't tell anyone I worked on an HP.

    At least 50% of IT is a solution looking for a problem.

    Your secret is safe with me. =^..^=

    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.

    HP what HP??? Don't know what you are talking about. Just make sure your Sales rep doesn't get wind of you fixing the issue.
