Says "cover open" but it is not

Hi,
Here is a great article on how to try to resolve the cover open error on the Lexmark X3470. http://bit.ly/aoOtEP

Try these as I found them from Lexmark's website

Solution What you will see
The printer displays a 'Cover open, please close cover' error message, even though the cover is closed.
Possible cause of the error
This can happen if the lever on the cover open sensor is knocked off the switch assembly.
What to do
Take the following steps to try to determine if there is a hardware fault:
Steps Actions 1 Remove and replace the cartridges from the printer. 2 Disconnect the power cable and the USB cable. 3 Check that the power cable is plugged directly into a wall socket. 4 Reconnect the power cable. 5 Close the printer cover. 6 If the error persists, please contact Lexmark Technical Support for further instructions.

Check if cover lid presses the cover botton

You have go to service, becouse the switch for cover is brouken, and they need put them ih close mode. In same primter model switch is in diferent placeses

Try looking around the edges of the cover or in the hinge area for a switch that may be stuck. Most covers have a switch to indicate that the cover is open, the cover may not be seated properly or the switch may be stuck in the open position.

Check every possible open "door" in the printer. Be certain that the cartridges are installed correctly. Check for even a small jam. If all else fails, "slam" the cover. Good luck

put your finger on the second hole on the top from the right and press the switch (it's small, gotta try a little...), when the display changes, press copy and close the door... it just worked for me!!
good luck

your printer needs to be opened and checked. plz ask some professional on your area to help you

you need to open cover and undo and remove the grey cover inside the printer as there is a switch at back of machine which has *** off

smash the POS with a hammer and go buy something else
