Re: Cover tab broken on Lexmark X3470

Have you recovered the tab? All the tab does is interrupt a sensor beam between 2 points. Either glue it back on (epoxy or super glue, use sparingly on one side then apply and hold down until it sets, about a min. or tape a popsicle stick into the area where the tab rested. First feel around with the stick in the area until the printer responds. then fix it there.

Lexmark x3470 printer says "cover open" and it will not do anything. Curtis

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.

Cover open is on display

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

There is a plastic lever in the back of the scanner where it comes into contact with a part made to push the lever when closed to work the switch. It is a poor design. The lever fits over the small micro-switch very loosly and the tabs wear out really quick. Lexmark will not send another lever. They state buy another printer. If you are real careful, you can put the lever back on the switch and hold it in place while you close the lid.
