How do I resolve the error message "Printer Access Door Open" (error code 3501 or 3609)?

If the error continues even after you close the printer access door, power cycle the printer:
  1. Turn off the power (press the On/Off button on the printer).
  2. Unplug the printer power cord from the back of the printer.
  3. Wait approximately 30 seconds.
  4. Plug the printer power cord into the back of the printer.
  5. Turn on the power to the printer.

When attempting to print, the printer window gives me the message Back Cover is Open Checked the back, opened it, removed the paper that was stuck on the roller and tried again. Same message comes up. What...


hello, when you are looking at the back end of printer, open up cover, the cover will open and stop, look further in and you will a black guide, or black plastic, open that up, if it does not open on its own, there is a piece of plastic that might look like a stick, sometimes this will get stuck, use a flashlight, and you will see haw this thing works, if it does not move freely, it will trigger rear door open, be carefull with this piece of plastic, it does break. again it will trigger an open rear door error.

Dell Laser MFP 1815 won't print. Message keeps coming up Jam 2 open rear and front door. Have opened and shut doors repeatedly, restarted printer, tried copying over message but it keeps being displayed....


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.

Back door closed


I did not get any error message but the 6940 printer would not print. Instead "Ready" the printer said "door open". When I deleted printer and plugged the usb cable back in the XP machine found the new hardware, said "Ready" and could print.
