Question about Lexmark X3470 All-In-One InkJet Printer
I HAD A PROBLEM WITH THE SWITCH KEPT SAYING COVER OPEN. GOT THAT FIXED. SCANED ONCE . I STARTED TO SCAN ANOTHER TIKE AND IT CAM PARTIALY OVER THE CLASS AND THEN IT STARTED TO CLICK. NEVER SCANED ACROSS AND LIGHT NEVER CAME ON. CHECKED THE BELTS EVERYTHING GOOD WHAT COULD BE CAUSING THIS. COULD IT BE IN THE BOAD OR DOES THAT LIGHT HAVE TO COME ON TO SENSE IT WHAT IT IS DOING. IS THERE A BIOS FOR THIS PRINTER TO.
With the help of google here is your answer
Your arm of cover sensor has fallen off'
Try CACY solution for a great quick fix
It is the switch fallen to bits
THis bit falls off
How yours looks
How it should be, or can be if you put it together again.
It might be possible to snap the part back on without partial disassembly, or simply shove something in there to hold the sensor in the 'closed' possition (If you lose a finger or two using this method, don't blame me)
The lid sensor is a tiny microswitch that is on the main circuit board...there is a white nylon lever arm snapped onto the switch.
if the lever arm falls off (like mine did) the 'cover open' error will last forever.
This may (or may not) be possible do fix without some disassembly. This lever arm should stick up through a rectangular hole that's approximately 1/2" to the right of the print head (assuming print head is parked in the middle) and behind it.
Most likely if your lever arm has fallen off, shaking the printer gently upside down with the cover open will allow it to fall out.
Now if you are a dentist or a surgeon, snapping the lever bit back on is no problem without taking anything apart.
I am neither. For the brave (of foolish) ones who like to do surgery, here goes. Here's how I took mine apart....if yours breaks into a million bits, don't blame me.
0) unplug the power and take the scanner cover off.
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.....

Cover open problem. If you open the cover, at the back of the lid you'll find a ramp-like tab. That tab contacts a poorly designed switch in the base chassis. If you follow down where the tab goes you may find the loose plastic tab or nothing. The tab acts lie a rocker that tells the printer the lid is open for cartridge replacement. if you touch it the cartridge slide will move to the center. To clear the error, you need the cartridge tab compressed. Since you now have a broken two cent tab, you can either buy a new printer or find something to jam down there to hold it closed. Recommend a piece of balled up electrical tape. The tab is pointless and you can change the cartridge without it.

Ok so as far as i could see i tried the picture above and my button was stuck in and still said cover open so i was in a lose lose situation fromt he beginning so i tried everything i read and nothing so i though ok you stupid thing you are coming off so i snapped it off ok not recommennded but with 2 kids screaming and dinner to be made i was annoyed anyway so i carefully snaped it off and just connected the metal connectors together if youare good a soldering you could do this but its working fine now so bypass the problem is my solution lol,
just dont blame me if you cant do it or break something you shouldnt.

Hold the white plastic piece from the top with tweezers so that the way you're pinking the tweezers is the same as the way you are forcing the piece down. And push it back on by applying a lot of pressure to the tweezer with your index finger.

SOURCE: WON'T SCAN
Did you have things apart far enough to mess with the scanner. The scanner should move to one side when it first goes on, and then trip a sensor (home position sensor). Also, the scanner is probably belt or cable driven. Check to see that the belt is somewhat tight, and that the gears and pulleys leading to the scanner motor are in place and not broken.
