XEROX 3300MFP "Door Open" but door isn't open

Product Name: Other - specify product in post



Our company owns like 4 different 3300MFP units.


One of them recently refused to print and started getting either "Door Open" or "Fuser Door Open" message. I looked around a bit online and I saw some potential fixes. I cannibalized the fuser and the HVPS from one of the units we keep just for parts and the "Fuser Door Open" has stopped, but I'm still getting "Door Open."


Everything I find online that isn't telling me to replace the power supply is "check and make sure the door is closed." I'm not simple, I know how to close a door, and I've checked multiple times that it's latching into place and not loose at all.


Is there anything else can be done? A sensor I can check? Even if I have to take out the power supply again (which is a bit of a process) I don't mind. It's not a life-or-death thing, we'll get new printers if we need 'em, it's more of a "I want to beat this machine" thing.


Thanks in advance
