Ok make sure the back door is fully shut.by opening it again and closing it firmly. If that doesnt fix the problem then unplug the printer and let it sit unplugged for 3 minutes. That will reset it.

please mark this answer as a fixya!

My laserjet pro 400 color mpf m475dn printer is indicating " paper jam...open back door to clear jam," please describe how i will go about this process.


There is an access door in the back of the printer. Open the door and you should see jammed paper. If not then you have a faulty sensor or switch.

I had a paper jam. Got the paper out, but now


Some printers won't reset the jam condition until you open a specific door or cover -- even if you've gotten the jam out, they think it's still there until you open that cover. Try opening and closing all of the machines doors and access points, and even pull out the paper tray and push it back in.

If the jam condition still isn't cleared, turn the machine off and back on with the main power switch.

Brother HL2030 laser printer. Paper jam, single sheet in machine, I do not have instruction booklet. Paul Bentley


There are several sensor flags along the paper exit route, if
any one of these flags stick or have broken the printer will
take the paper so far then shows jam.

remove the drum unit first then the paper jam, look directly
into the printer to where the drum unit sits and check to see
if one of the flags is sticking up-rite in the centre area.Its spring
loaded so as you push it back, it springs forward again thats ok

Remove base paper tray:
The other flag is at the rear and can be accessed by opening
the rear door and then by opening the inner paper exit ***'y
you can then see the flag on the exit ***'y,this is also spring
loaded. If any of these are out of place/stuck or broken a paper
jam will always occur.
let me know what you find!!

Paper jam


Sounds to me like the paper jam switch is broken. Open the back door and look at the center where the paper feeds between the rollers. There should be a small plastic switch actuator sticking up, it probably got broke off.....

Props to Profjake. I followed his advice and problem solved! Here is what I found out.

I had the "Back door open" error on the LCD panel. There is a "interupter" type of sensor that detects if the back door is open or closed. When the back door is closed a lever is pushed forward and blocks the interupt module. The lever that blocks the sensor was not reqching the sensor horizontally - it was too far to the left. The lever on the far right is part of a 6" rod that goes across the middle of the paper path. The rod had jumped out of it's "home" position to the left and it was bowed a little bit. I carefully re-seated the rod to by gently lifting it and moving it to the right into a slot 1/8" from where I found it. The error cleared immediately. The was most likely caused by removing a paper jam.

Once again props to Profjake as his advice led me to the solution.

Hu said that!
