How do I resolve the error message "Printer Access Door Open" (error code 3501 or 3609)? Published 08/25/2010 11:38 AM ' Updated 01/07/2011 08:40 AM ' Answer ID 1467 How do I resolve the error message "Printer Access Door Open" (error code 3501 or 3609)? To resolve this error, close the printer access door. The printer will not operate while the door/cover is open.

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.

I have fixed this problem on my 7820n printer by brother.

open the back door, then inside there will be a black colored other kind of like door that pulls back away from the roller. on this inner door is a black long thin plastic lever that runs from about the center of the inner door to the right. on the right end of it is a lever that slides along a curved increase on the right side wall. when both doors are closed this right end of the rod or lever moves up to close the gap between what is the sensor. this long thin plastic rod had snapped out of place and when i snapped it back in making sure the spring was correctly installed on the left end of it and the middle part of the rod slid correctly in its groove...the right end of the lever correctly closed the gap on the sensor (when both doors are closed) and the back door open error went away.

So that's how you really fix it!!!!

I had the same error message. I also tried every compartment... Here's ultimately what my problem/solution was...

I turned the printer around and fully opened the back cover. I found that one of my kids had somehow fed a small piece of paper/cardboard into the printer. When I opened the back cover all the way I could see that obstruction (which I hadn't seen before). Pulled it out, and the error message went away. Works fine now.

Something is holding the top cover on the printer open enough so it is not pressing the switch to tell it it is closed, OR there may be a back door on the printer that is not fully closed. Many printers have an access door in the back for clearing paper jams. If the back door is not fully seated and latched it will cause an error.
