Lexmark X3480 Printer

I have a problem with cover open although it is closed, i am trying to find out where the switch is so that i could close it myself or replace it. Any ideas on where i could pick up schematic diagrams for this model would be appreciated. I did call tech support n they r as useless as i am.

    Same issue but have no white arm (must be lodged somewhere as i have shaken and shaken, and shaken).

    One solution is to wedge one of the 3 different levers (That all connect to the same point) open. I've done this with the lever that sits directly behind the printer head when it comes to the centre which solves the 'Cover Open' issue but then initiates a 'Paper Jam' error message. Un-wedging this lever then leaves the printer useable but obviously this is not a long term solution.

    Without the arm to snap back on, is there any solution?

    cover open error will not clear. even when cover is closed. will not shut off by depressing power button. have you any idea how to resolve this issue? i've tried to find the problem by unplugging. can't locate lever that activates cover open message.

    My X3480 started to display 'Cover Open' the first time I changed the ink cartridge. It has not worked since. I have tried the solutions offered by fellow sufferers to no avail. This is clearly a design fault - so why is Lexmark in denial? I agree their Tech Support is useless. They should hold their hands up and replace all machines with this problem even if out of warranty (I bought mine as back-up over a year ago but I've only had one cartridge of ink's use out of it).

    (PS: My solution: Drive your useless Lexmark X3480 to the seaside and drop it over the highest cliff you can find. This ensures you have to buy a replacement printer thus solving the problem. Never buy another Lexmark product - ever!). [email protected]

    I had the plastic switch/lever rattling around in my Lexmark X3480 after i changed the ink cartridge,closed lid and got message-Cover open-which cannot be cleared and you cannot power down the printer other than pulling the plug from mains socket.
    I saw the above pics and stripped my lexmark apart,found the white plastic lever and re-attached it as in pics,put printer back together and now working fine.
    Thankyou Soulvisitor.

By using the hints of several entries, I located the 'plastic piece' , where it goes, etc. however, I could not get the piece to fit back so I taped the tiny black button and FINALLY!!! it is working again.. by looking at the 'best solution' on this page you can locate the right spot and if you feel inside, on the top is a tiny black lever/raised piece, when it is pushed, the printer instantly reads insert paper, etc. instead of that INSANE cover open..

GD day mate, Im having the same problem except that my printer is a Lexmark X1185 All-in-one printer. Right now, I'm holding the same plastic piece as the one your holding in the picture but I've no idea where it should be or how to dissamble the printer. What did you do to take apart the printer?

Posted on Feb 20, 2008

Printer shows cover open message. The small plastic lever that operates a switch can pop off. If you can retrieve the plastic lever and remove the hinged top of the printer you can put it back in place. It's a bit fiddly but I did manage to do it.

Hi Just wonder if you could help me i have a lexmark x3480 it has suddenly decided to display cover open and is not switching off at the control panel. The cover is not open and sits flush what is it...

It could either be due to a stuck cover sensor or the cartridges in your printer. Please follow the steps below to fix the problem:

1. Make sure the printer is on.

2. Open the printer cover. The print cartridge carrier moves and stops at the loading position, unless the All-in-One is busy.

Note: If the carrier does not automatically move to the center, turn off the printer/unplug the printer from the power source and then slide the carrier to the center.

3. Remove both cartridges from the carrier.

4. Close the printer cover.

5. Rebrick (pull out the power supply, black box where the power cord is plugged in at the back of the printer, and put it back after 30 seconds).

6. When the printer turns on, reinsert one cartridge first.

7. Close the printer cover and check for any errors.

8. If no error appears, reinsert the other cartridge. Close the printer cover.

9. Replace whichever cartridge is causing the error to appear with a new cartridge.

If problem continues, please contact Lexmark Technical Support Center for additional assistance.

I changed my ink cartridge, and now it has cover open displayed but the cover is closed

when you open the lid there is a small white piece of plastic witch should be attached to a very small micro switch .this keeps coming off for some reason .you have to find it and reattach it to the switch that is just right of the middle of your printer .hope this helps

Message says lid is open when it is closed


Please try out the blow mentioned 2 options. I am sure the problem will be sorted out:

  1. When you lift the cover up along the back end of the gray plastic bottom cover, you'll see a square opening close to the right side hinge.
    There should be a little white plastic piece sticking out of there. If not, it fell into the guts of the printer. You have to remove the gray plastic and find the white lever and replace it onto a micro-switch along the back where the square opening is/was.
    You'll see a PCB (printed circuit board) there and the micro-switch will be located on that...
Hope this helps

2. Remove the screws on the front of the cover when it is open. Once removed At the back of the unit 2/3 rd from the left there is a small switch if this is pushed in ( and held by whatever means sellotape etc it will opperate normally (to change cartridge you may have to re do)

X3480 printer.message is saying;cover is open

the meaning of cover is open means --------the cover means.the thing which you lift to remove or install the cartridges.just keep that cover closed.if that cover is closed still its showing the same error.then the sensor which detects the cover closed is got moved from its orignal reset the sensor just tap all the sides of the printer for couple of minutes.mostly the top side and front side of the printer.and then check out the error must go away.if still the same error then its quite possible that sensor is broked as it very very delicate .so it needs a technician to replace the broken sensor.the cost to replace the sensor must not exceed then $5.

Lexmark 3480 cover open

Hi I have 30+ printers and each differs but sorry I do not have your printer. But generally you will find a corresponding female recess somewhere around where the lid closes on the main frame of the printer.

Hope it helps

Cover open error

There is a latch that preses a small switch when you close the cover (look for this) to indicate that it it close if it is broken you can tweek it using a toothpick or anything that may press the switch temporarily this may alow it to work as long as the switch stays down.

X3480 cover open message

Ajkill is right, although his description isn`t very exact. Take off the complete scanner part: (back hinges first, then the blue arresting lever at the front), disconnect the flat band cable and the power supply for the scanner part and take off the complete scanner part. You´ll see a triangular part that goes in a slot of the dark grey cover which covers the rest. It should press againt a white lever which itself presses a little black switch sitting on the printed circuit board. If this white lever has fallen off the switch is always in "Cover open" position. To get it and reposition it (if it isn`t broken) you have to take off the dark grey cover which covers all the rest: take off the front screws and carefully lever out the sides with a small screw driver. Good luck with the repositioning, it is very fiddely and to see how and where it has to go you best use a magnifying glass!  But I could manage it and my printer is working now again. And good luck with fitting it all together again without breaking anything!
