    Lexmark X3470 scanner clicks (drive belt passing through scanner head clips) when powered up. Clicking stops eventually but scanner head will not light up or move more than an inch back and forth. Tried repositioning scanner head on belt and manually rotating head to stop position but belt will not stop moving when scanner head is nested at top of page.

    Scanned some pictures. Later opened printer to change cartridge and when I close the printer, it keeps telling me the "cover is opened". It is not, but don't know how to solve the problem.



    Thanks

  • dick18 Nov 25, 2007

    I have the same problem too. I went to change the ink cartridge and the cover thinks its opne whne it really is not. I find this odd that the 4 of us all have this same problem. any ideas out there how to fix it. I even went to Lexmark and they were stumped too.

  • Anonymous Nov 25, 2007

    I had the same problem. After changing the ink cartridge (for the first time) it said "Cover Open" and it was not. Lexmark sent me a new printer when it did this as they could not troubleshoot by phone. Now the new one is doing it also....and this is only the 2nd ink cartridge for this machine. Poor product. Does anyone have a solution?

  • Khamellion Nov 26, 2007

    I have the same problem. I recieved this problem a year ago as a Christmas gift & after only two changes of the ink catridge mine is now saying the same thing. It's clearly not open. My mother cannot find her reciept so I cannot get a new one. I am a college student & I really can't afford to purchase another one. What do we do?

    Hi all, I have the same problem, just changed the ink cartridge and Cover open, I have unplugged from electrical source and from the processor turned off it will not go away or reset. It is irritating when one has not gotten the use one would expect from a product. Not to mention the use of the ink. Thanks for letting me know when there is a solution.

  • Linkmeister Dec 09, 2007

    I opened the cover to determine which cartridge I had installed, closed it, and now see a "cover open" message displayed in the LCD screen. I've lifted the cover, jiggled it, and unplugged it from the wall to no avail. The message remains "cover open."

  • lewisc7 Jan 05, 2008

    I had the same problem removed the plastic tab and taped the switch. But nowmy paper goes down and james. I removed the whole chassis and cleaned everything. The rollers where the paper feed is at rolls the paper down but the rollers down close to the ink cartridge rolls the opposite direction causing a jam.

    Hello . . . my 3470 says "cover open". I've had the unit for just over the manufacturer warranty coverage (1 year ). I've printed about 100 pages so, just a bad luck situation. Before I purchase another 3470 or maybe a 2470, can you help? My e-address is jdublyuh@gmail.com



    Thank you for any reply

  • RoosterCrows Feb 17, 2008

    I HAD THE EXACT PROBLEM WITH THE SWITCH KEPT SAYING COVER OPEN AFTER CHANGING INK CARTRIDGE WITH THE EXACT RESULT. I GOT THAT FIXED, NO PROBLEM, NOT THE FIRST TIME. IT WANTED TO DO AN ALIGNMENT. I STARTED TO SCAN AND IT CAME PARTIALLY OVER THE GLASS AND THEN IT STARTED TO
    CLICK. NEVER SCANNED ACROSS AND LIGHT NEVER CAME ON. CHECKED THE BELTS & CABLES,
    EVERYTHING GOOD. WHAT COULD BE CAUSING THIS PROBLEM? PRINTS FINE AFTER THE SCANNER TIMES OUT AT STARTUP. EVEN RELOADED DRIVERS.

  • ashsherman Feb 18, 2008

    scanner head moves just a bit and then clicks like mad. Can't even power off.  Disconnected power connector inside machine and printer works fine.
    I thinks it got locked somehow. How do I fix this?

  • louis1959 Feb 18, 2008

    the display shows "Cover Open" all the time. When I try to activate the internal RAM programming by touching START and POWER at the same time, I get the Mfg menu prompt, but that disappears as soon as I release the START and POWER keys

  • RoosterCrows Apr 13, 2008

    Please read these posts. The problem starts with the door open thing.
    When that is FIXED, a physical problem starts with the SCANNER!



    IT'S THE SCANNER THAT NEEDS ATTENTION AFTER THE SWITCH IS FIXED. There
    is a reset code on the front panel that did not work for me and don't
    remember what the process was now as I have already put this machine to
    it's best use as a boat anchor.

    I have the same problem and spoke to the help desk via email the fool must know that people are having the same problem with cover is open I'm so pissed because I only use this printer three times

  • Anonymous May 22, 2008

    I also get the "cover open" alarm and find the white plastic actuator arm broken. This is a new printer still with the original ink cartridge.



    Funny thing is, it was working fine but I was looking it over to determine the failure mode for a friend who's identical printer was broken... and when I lifted the lid for the first time,,, the poorly designed plastic arm fell off the switch... I'm calling Lexmark and everyone else needs to too. Start with their customer support desk 1-800-5396275

    i tried to print and it said cover is open. i just opened and closed a few times and still the same. obviously a bad product. i unhooked it and have been without ever since. i'm going out to buy a different product. brand new and of no use to me at all. bought from walmart and they do'nt even carry it any longer. what does that tell you.

  • 98roadking1 Jun 27, 2008

    We've had that problem twice with our 3470 model in less than a year. When you change the ink cartridge, there is a small plastic part in the back that breaks. we were able to fix once. Had to change the ink cartridge and this time we can't fix. Anyone need a box to elevate their monitor? Don't know what else it's good for. Wouldn't you know, we just bought a 3 pak of new ink cartridges...

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 switch
LEXMARK X 3470 - dc8e21d.jpg
THis bit falls off

How yours looks
52ec442.jpg
How it should be, or can be if you put it together again.
f1af700.jpg
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.....

    Rodderick I'd say you have damaged the flat ribbon cable, they are delicate -

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.

    Took a little while to find the switch (it is up toward the fron of the printer), but this fixed the problem. Thanks CACY

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.

My lexmark 3470 the screen says cover open and it isn't. Help


Hi there
It is seeing it open because it may be the sencer or switch on this cover is broken or stuck open have a look at where the sencer or may be a switch.
Some times if you handy with your hands you can do some thing about it like stick some thing in the switch hole to click it on or if it a sencer put some tape over it then it thinks it closed.

When I scaned my finger it said Too Short and will not open


Well first of all, get ***********'s finger to scan. The system probably locked you out because it doesn't recognize your fingerprint.
And if you have scanned your fingerprint as a key PRIOR to this situation then wait for your computer to load then calmly swipe your finger again.

I have a LEXMARK X5650 that will not SCAN to the computer... When I press SCAN it does nothing. So I press the ON and START buttons... The display will then say "Scan to Computer" - If you click "OK", then...


When using Adobe Photoshop, select File, then Import, and then the Lexmark device. That's the only way I have found, however you should be able to scan through many programs.
