Back cover open message although cover is closed

Hi. You have to follow these steps: Be very careful:

1. Open front cover, like in this image:


2. Pull out your printer's toner cartridge & drum unit:


3. Open back cover


4. Pull the tab which is in front of you in order to open the rear chute cover.


5. If there is any, pull the jammed paper out of the fuser.




6. Close back cover and put the cartridge toner & drum unit back where it belongs.


7. Close front cover too and see if it works! If your error will still appear, try powering your printer OFF & ON

I hope I helped you!

raise the cover and see if u can see a switch of some kind puss it down and see if it will print or restart ur computer and see what happens

Problem is simple, your system having sensor which indicating that cover is not closed. uncover it once and check sensor push button may be not connection well. recover casing and ensure its not loose.

There will be a microswitch that is operated by opening/closing the cover. Presumably the switch will be where you have a piece missing from the top.

You just need to find a way of closing that switch. That can be done mechanically with a piece of tape, or you could short circuit the switch if you can get to the wiring.

The printer displays a 'Cover open, please close cover' error message, even though the cover is closed.

This can happen if the lever on the cover open sensor is knocked off the switch assembly.

Actually, you need to double check the back cover and front cover, open them all to check all paper jam.
Besure to check the back cover, normally all paper jam is from the back.
be sure to close the front cover at the last cover to close.

what's the error say?

It's when putting the card in.. typically you put it in and it clicks (so to speak).. if you delay removing your finger-push, it does something to the card and makes a Disconnect, although in looking at it, it looks just fine.. and the cover closes... A lot of people are reporting 'door open' errors. The micro-switch in the door housing is quite sensitive and pressure shifts from your hand on the door can cause it to trigger as if the door were opened. some get progressively worse. One fix is to add a little bit of length to the plastic that contacts the switch, either a layer of tape or a drop of epoxy, etc. This may help (or may not if the switch itself is flaky). Another fix discussed bypassing the switch altogether, obviously not for the faint of heart (or cameras in warrantee).
