Question about HP Office Equipment & Supplies
My HP colorjet 2605dn displays a ''door open'' error message and an orange light blinks, even though no door appears to be open.
On the memory controller board (the unit inside the printer which each toner unit makes contact with. If you open the front door and remove each toner,you will see a row of 4 contacts plus 4 leds and 4 receivers, encased in a metal casing/guard), there is a small white actuator, just to the left of the black toner,which is coupled to the scanner shutter lever.
If this is not correctly coupled, it will result in the "door open" message. The white actuator should spring back out towards the front of the printer when you press with a small flat blade srewdriver and release.
I had to remove top cover, rear plate, lhs covern High voltage psu and the memory controller board. I made sure the shutter lever and the actuator were set correctly and reassmbled.
Door open message was resolved.

SOURCE: HP 6940 will not print
Turn the printer off
Open the back door and
gently turn the paper roller upward until it clicks. Make sure the door is securely closed. Wait a few more minutes then turn the print back on. I hope this helps.

I had the same problem, and the cause turned out to be the cover switch not being fully pushed in. On the underside right edge of the top cover, there's a little triangular protrusion that pushes down a black rectangular button (the cover switch) when the cover is closed. The problem occurs because the flimsy top cover is made of plastic and flexes slightly when you close it. This means that sometimes, the right edge of the cover won't seat properly even though it appears as if the cover is closed all the way. When this happens, the triangular protrusion isn't fully pressing the switch down.
To test if this is this is happening, send a print job to the printer and wait for the "top cover is open" error message to appear. Next, open the top cover door and locate the cover switch. It's a little black button in a rectangular hole at the right edge of the doorway near the ink cartridges. Take a pen or a car key and use it to push the cover switch down. You can also use your fingertip to do this if it's skinny enough. If you keep the cover switch pressed down, the power button should start blinking to indicate a print job is coming through. If the print job actually starts printing, then you know the problem was the cover switch.
In my case, all I had to do the fix the problem was close the cover and make sure it was fully seated by firmly pressing down the right edge of the cover until I heard a plasticky "click" noise. After that, the problem went away.
Hope this helps.

Here's the answer:
The sensor is probably stuck, and it took me a few minutes to fix!!

Double check EVERYTHING you disturbed when you replaced the Transfer Belt.
Probably 2 things not connected properly - fan obviously, and a sensor.
