    Lexmark C736n "Close Front Door" message

    There are two interlocks along the right front of the primary transfer/drum units assembly. The first is a small black plastic feature that engages with a slot in the right hand rail. The second is a microswitch. Both clear at least momentarily. Both switches test fine ... then close front door message again. Has anyone seen this? =^..^=
    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.

    Cat - If you want the service manual for this machine, just shoot me an email and I'll send it along at no charge.

    Best Regards;

      2 things. have seen one of these do this once after the main drive was replaced. it wasnt installed correctly and when it tried to start up it would say to close the front door. dont remember exact details but after removing and reinstalling a couple of time finally figured out what i was doin wrong

      the other is that it looks like all the door switches run straight to the sys board. so that could be the issue also if not the later.

        I haven't dug in quite that far yet. Thanks for the comments though.

        When I press the microswitch I can hear a fan shift to high speed, and a drive motor to come on, so I can be fairly certain that the switch itself is not the issue. =^..^=
