I had the same problem, however I am also using VoIP which I don't think it matters. Solution: First, be sure you are using a 4-wire telephone cord (has the red, black, green & white wires on the end of the jack). Then you will need to add a DSL filter to the phone line between the wall jack and the fax machine. In my case, I plugged the filter in the VoIP box and plugged one end of my fax line into one end of the filter and the other end into the fax machine - fax slot. if you have a filter with multiple slots, be sure to plug it in the telephone line slot. As soon as I completed the process and tested the fax line it connected and worked just fine. I hope this helps.

SOURCE: front door open message it won't print

There is a switch inside the front door that is not making contact when the door closes, making the printer think that the front door is open. The switch is recessed in the housing. Look for a plastic knob that protrudes from the front door that will mate with a hole in the frame. Inside this hole is the switch. Try activating the switch manually with a screwdriver to make sure the switch is functioning. If it is, you will need to take off the cover and reposition the switch forward. If it does not activate manually, the switch must be replaced.

I had same problem. If you go to rear of printer and open the back door you'll see it is attached to a blue connector. Unattached it so that the door opens fully and then unflap the inside roller assembly. Next open the fuser door and you'll notice a little spring loaded assembly on the inside of the opened fuser door. This is where my problem was. Make sure that the assembly springs back when pushed because part communicates with a sensor on the motherboard. If it doesn't spring back then the printer thinks there is a jam. Mine was stuck but after pushing it a few times it started to work freely again. This was a frustrating problem but that fixed my issue and hopefully it will fix yours.
