My printer is giving message that you rear cover is open for that what to do?

I have a problem with my panasonic printer when i have start my printer msg display check rear cover...plz help me.

After a paper jam occurs in the rear cover of a Dell Laser Multi-Function Printer 1815N, the printer will not resume when the jammed paper is removed. This is the normal behavior of the printer as there is no sensor on the rear cover of this printer.

To open the back cover and remove any stuck paper, perform the following steps:

1. Open and close the front cover.
   The jammed paper may automatically exit the printer. If the paper does not exit, go to the next step.
2. Gently pull the paper out of the output tray.
3. If you cannot see the paper in the output tray or the paper does not move when pulled, open the rear cover.
4. Skip to step 9. If you do not see the paper, go to the next step.If you see the jammed paper, push the two blue pressure levers up and remove the paper.
   
5. Release the blue strap, the rear cover stopper, and fully open the rear cover.
6. Unfold the duplex guide fully.
7. While pushing the fuser lever to the right, open the fuser door. NOTICE: Make sure to unfold the duplex guide before opening the fuser door, or the fuser door may be damaged.
   
8. Pull the jammed paper out.
9. Return the levers, fuser door, rear cover stopper, and duplex guide to their original position.
10. Close the rear cover.
11. Open and close the front cover.
    Printing automatically resumes.

If the inner cover is open when starting normal printing,close it before pressing [OK] on the machine.Do not open or close the inner cover when printing.This may damage the machine.

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.

the top cover that opens to the left normally has a small piece of plastic that slots into a sensor toward the back of the adf. this small piece has broken off so the machine thinks the adf is open. an engineer would need to replace the door for you.

I have a small piece of paper jammed in my Canon MX-860 that Cannot be seen from anywhere. Can you help me find so I can clear it

if you open the platen cover, on the rear middle there is a little opening, that is where a little actuator sensor sit, and it is sticking... take a little flat screw driver and kinda flicker it.... that should take care of your problem

Try doing the following prior to messing around with the fuser itself:

Had the same problem myself but discovered that I had previously moved the inside flap down when I put the ink in. I moved this back into position and bingo! (If you make sure all the covers are closed then look into the printer where the paper exits you will see the flap that moves up and down, this must be in the up position)

Just check may bi cover is not locked properly .and also check there will bi a sensor having some bad sector .just clean it properly.or replace it MIA AKHLAQ
