SOURCE: Lexmark 3400 scanner/printer says COVER OPEN. IT IS NOT!
Took a bit of time but worked 1) release the 'kickstand' from the scanner by prying and squeezing it with pliers until the two prongs pop out (or crack and break) 2) detach the scanner hinges by prying/squeezing with pliers until they pop off (or crack and break). (CAUTION: read step 3 below first...don't just yank the scanner off without reading step 3) 3) Carefully unplug ribbon cable and other connector to scanner and set scanner aside. 4) remove screws at front of beige plastic part....pry at the back carefully and this will pop off....sending the screws flying if you left them loose in their little wells. Don't worry, there are only two of them that really do anything anyway. 5) Look towards the rear of the printer and you will see the circuit board and the 'hole' where you can see the sensor, and possibly your white nylon lever arm lying pathetically down in the bowels of the printer. 6) Retrieve and Carefully snap the nylon lever arm back on, and think nasty thoughts about the brainiac who designed that part. reverse the above steps. Put at least most of the screws back in, or the front panel may fall off at a later date. Take care to GENTLY plug the ribbon cable and the other scanner connector back in, making sure it's seated all the way. Try not to bend or kink the end of it, or it will be toast. Good luck, and happy lexmarking.....

May be the cartridge not fitted properly.
Also try to unplug the printer during PC on. and then replug it.
Try to power off printer, restart PC and disconnect USB, then connect after restart PC.
Let me know if you need further help.
Sometimes the ink cartridge carrier
won't automatically move to its loading position even when the printer is on and
the cover is open. Follow the steps below:
1. Unplug the printer from the power
source. 2. With the cover open, hold the
solid white strip that connects from the carrier assembly to the ink cartridge
carrier and gently slide the cartridge carrier to the center of the printer. 3. Remove the used cartridges. 4. Load the new cartridges. Close
the cover. 5. Plug the printer back to the
power source. You may also refer to this link: How to

It could be that the cartridges are not seated well in the carrier or the top cover sensor got stuck. Remove the cartridges from the printer. Close the cover. Unplug the printer from the power source. Replug after 30 seconds. When the printer's ready, reinsert the cartridges. Close the cover. Make sure you are using the compatible cartridges for your Lexmark X3400 series printer.
