Lexmark Lexmark Optra T

X3470 Lexmark

The display reads "cover open". The cover is not open. I have opened and closed the cover. I have unplugged and plugged the printer. I have uninstalled and reinstalled the printer software. The power button automatically comes on when I plug in the printer. I can't shut down the printer. Does anyone know what I can do? This printer has hardly been used. I opened the cover to see what type of cartridge I needed and this happened. I have also removed and reinstalled the cartridge. Nothing has removed this message.
I have four pictures of the repair.
(They are a bit blurry, but it should help orient you.

1. Cover removed showing Circuit board at rear right.
2. Lever arm that falls off, producing the error
3. Shot of the Circuit board "whole" with the arm missing
4. Shot of the Circuit board "whole" with the arm in place.

Note: in the last picture, the "arm" is colored black and is sticking up.

If you need them, email 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.....

I wish to thank you very much for taking the time to type this rather detailed set of instructions for repairing this most irritating and uneccessary problem. I tire of these companies that produce cheap and poorly thought out engineering to save money or to cause you to buy another printer and make more money. It took me and hour or so to disassemble and reassemble my printer, but it did work and I would have had no idea how to do so had it not been for your generous contribution. Thank you again for your exellent entry. - Anonymous

WOW!! It worked for me too! Lexmark tech support suggested I purchase a new printer because there was nothing they could do. So I started searching the internet and I found your information, gave it a try and now my printer works just fine. My suggestion to anyone else would be to point the lever downward with the 'slit' facing up and it will snap right on (as I wasn't sure which direction it should go). My printer went back together very easily. Thank you! Thank you! Thank you! - Anonymous
I had this same printer for 4 years. Recently had to replace ink cartridge and had the same exact problem. Had it apart for a couple weeks searching for the problem. I wasnt going to give up ,especially after just spending $25 for the ink?Glad i found your posting.Thanks for your help.Printer works perfectly now.
THANKS! You even posted pics? - Anonymous
TAPE it!!!!!!!!!!!!!That is what I did.I made sure,I connected the printer to power, after I was done and before I put it together again. It works like a charm.!!!!! - unknown
hi i turned my printer up side down and shook it gently and it got that problem off and now it is saying click start to unclog the paper jam when there is no paper in it and i click start and nothing happens what do i do? - unknown
With the printer disassembled, the microswitch is a small black rectangular bit, with two on each side. On the nylon lever arm there are two little 'points' of plastic on the inside....these are the pivot points. The part is 'split' at the back so it can be spread out a bit and snapped onto the microswitch.

It's not easy to do, even with the printer partly disassembled.

More info please! Left right up down--where the heck is the small black rectangular bit with two holes? I'm looking strictly at the back of the circuit board, right? thanks
by Anonymous on Jun 1, 2007 at 8:17pm Add comment
First of all, note that on the cover, there is a pointy part at the rear approx 3 inches from the right hinge. That's the part that pushes down on the sensor lever.

The black rectangular bit is a microswitch.

it looks sorta like the one at the right on the wiki entry above.

The lever arm snaps onto the body of this switch.

The main circuit board of the printer hangs vertically in the back of the printer and has a black plastic shield over about 90\% of it (probably to keep dust and fingers out).

The microswitch is rectangular shape and is oriented's on the circuit board very near the top. You can see the tiny button that the lever arm pushes...this button faces the rear of the printer.

I've googled the internet for a photo of this thing, but so far no luck. If you can't figure it out, I will disassemble my printer and post some digital photos of it.

Your explanation was perfect! My printer is up and working again. Yes, I did have a tiny crunch on one of the hinges, but it still works fine! I could not figure out "where" that black switch was! Last night (before your help) I found a (lower and to the right) black lever, which made a little metal thing (directly below the switch) move--which was interesting, but NOT what I needed. With your help, I found the correct switch and FIXED my printer.

Once I figured out where to mount the white lever, (which took about 2 seconds to gently snap on) I did need my youngest son (he has tinier fingers) to re-attach the ribbon (took more time than the switch). I encourage anyone to give it a try! I am NOT a fix-it kinda woman; but I did it!

Glad to hear the mystery of Lexmark cover-open has been solved. The internet is sometimes very useful for that sort of thing.

I still think that Lexmark made a poor design choice by making a sensor arm that can pop off so easily.

If I were designing it, I would have put a pin thru the switch with an e-clip on each end. But I guess that would add another $.002 cents of cost to the printer.

I am trying to fix my printer x3470, Do I have to take out the black plastic shield which is attached the main circuit board?

I see the sensor but I do not see the microswitch. I can not open the black plastic shield....

by Anonymous on Jun 12, 2007 at 9:40am Add comment
No, there is a gap in the black plastic shield. On mine the white nylon lever arm was caught in the gap or hole in this shield.

Note that there is a pointy bit on the lid....this is what presses down on the lever arm, which is supposed to be snapped onto the switch.

OK, so I did all of your instructions and I am still getting the cover open message of death. The pulleys under the glass on the scanner are just knocking back and forth like they are jammed. The head of the white lever arm goes upwards correct as the long part faces down? I followed the exact steps listed and I still get the same message.
by unknown on Sep 4, 2007 at 4:34pm Add comment
if the white lever is installed correctly, when it pivots you should hear a soft distinct clicking of the microswitch it is attached to (when you operate the switch).

I suppose that it is possible that part of that switch or lever broke, or the switch itself is bad. You could probably shove some tape or something in there to hold the switch shut, and remove it when you need to change cartridges.

If the scanner is acting weird, make sure that the ribbon cable that connects to the cover has not become partially unplugged. Worst case would be if that ribbon cable were damaged. Hopefully it just needs to be re-seated in the connector.

Boy these printers are well made, aren't they??? (not) - Anonymous
Thanks for the direction guys, it worked a treat for me too. The only bit that wasn't immediately clear was where the rocker had to be positioned. Once I figured it out I took a photograph which you can see at:

I was able to follow Rob M's directions and repair the Lexmark 3470 without dismanteling the printer. I shook the printer upside down and got the white plastic lever out. I popped off the scanner cover to get it out of the way. I slid off the rear paper holder to get more room. Then I lifted the infamous "cover" up and only popped off the right hinge; therefore, I did not have to disconnect any wires or screws. If you slowly apply gentle controlled pressure at an angle the right hinge pops out like a tooth without damaging the hinge. Now there is enough room to snap the white plastic lever onto the black plastic switch that has a tiny tiny silver pin sticking up. The white plastic lever should point up toward the hole in the back top of the printer, opposite where the "cover" has a white wedge that pushes onto the white lever to click the switch on and off. In other words the gripping part of the white plastic lever goes in first toward the switch. Then push it down and snap it on. Now reverse the directions and snap it all back together again. I was able to do this without any tools and without a hemostat to hold the white plastic lever. It took about 20 minutes the first time. If I had to do it again it would probably take about 1 minute, but I am a dentist.

I too have the same problem of cover open. I fix mine by first remove the bar that holds the lid up.

(1)Just pinch it together easy and it will come out of the bracket.
(2)Then remove the lid for the scanner by just lifting and pull easy
and it snaps out.
(3)At the two back hinges press on the two hold sides and pull up easy on the lid. Do one side at a time.
(4) Now check and see if the white bracket is still on the switch and if not snap it back on. Then take some tape and tape it to the housing in the close mode. It will always be in the close mode and works just fine. You do not have to take it apart just take the two lids off and replace the plastic switch back on and tape it to the housing. You do have to remove the paper back holder. It to snaps out of it holder.
Hope this helps. It took no more than 10 minutes to do. Make sure to unplug it first.( both connection)

I had an easier solution!

It took three phone calls to get it fixed.

I called Lexmark support but unfortunately my helper was an Asian girl who didn't have a good grasp of English to be handling complaints.

After she told me that unless I had original receipt There was nothing that could be done .

I saw red and called Aldi where I had bought the printer, on a money refund deal, accounting for no receipt, as part of the deal was to send in your proof of purchase.

I was lucky enough to get the purchaseing manager who said "leave it to me" a day later I received a reconditioned printer that although I couldn't get the lid down every thing worked.

The manager called me to say I would be looked after if I called one of Lexmark's managers whose name he gave to me.

I had a pleasant conversation with this person who agreed to send out another printer this one WORKS fine.

It cost me nothing for freight either way as a prepaid voucher was included with the printer.

So I must say it was a lot better than pulling the printer apart.

This is true.....until it breaks again. This model is a solid little printer with one design flaw that was infuriating. i personally replaced three different ones via phone support with lexmark before i stumbled onto this site and repaired every one when they eventually repeated the error....

Well, here is my contribuiton.

I've read this post today and I was able to fix the "Cover Open" problem. The message started to appear when I replaced the ink cartridge. The white piece on the pics falled out of the place. And the "surgery" to fix it tooks I guess 40 minutes.

Thanks for the advice. I'm still struggling with getting the scanner hinges to let go in order to remove it, but that's a function of not having another set of hands at the moment. The rest of this seems simple enough.

I wonder if more recent Lexmark models have had this problem re-engineered. The first solution offered by the guy I corresponded with at Lexmark was "we'll send you a new printer if you have proof of purchase." Well, that wasn't an option, since the box and the CC receipt were long gone (an oversight I plan not to repeat; note to self: set up filing system for electronic widgets), so I asked for another suggestion and got nothing.

i have another possible fix. after i got the top off, i CAREFULLY supported the top with out removing the ribbon connector. i tried to put the lever back on, but it fell off again as i tried to reassemble. as i cursed, i decided to use something else to trip the micro switch. i used a piece of the cardboard from a cartfidge box, bent into a squared "C" and taped it in place with electrical tape, working in the small opening. it's not easy to get fingers, tape, and the cardboard into the hole, but so far, so good.

i went through taking everything apart an trying to put my switch back on but my switch had apparently fell off. so pretty much i summed up that when you up the cover, where the ink is placed there is a hole that where the switch it placed, and you will feel a little lever like a little tab if you place your finger in the hole. and all you have to do is pretty much put a piece of a tape over it and it's resolved in 2 seconds. it solved everything and there was no need to take apart the printer or anything.

Thanks for contacting Lexmark Customer Support

Someone will be with you shortly...
[Lorna Doone] X3470 cover open error message
[George] Welcome to Lexmark Chat Support.
[George] Hello Karyn, I will help you to resolve the issue.
[LD] hi and thank you
[George] Please re-confirm the printer model?
[LD] X3470
[George] lets began with the SELF TEST. please follow the steps given below.

1.Turn the power to the printer off by pressing the “Power” button once.
2.Press and hold the “Start” button and the “Power” button.
3.Once the screen will display “Mfg Menu Enabled” release both buttons.
4.Press the “Mode” button 3 times. All of the indicator lights will go out and the screen will display “LCD Button Test.”
5.Press the “up” arrow button two times. The screen will display “Single Test Page”.
6.Press the “Start” button once.
7.This will start the Self-Test. Once the page has printed, the printer will stop. The test is not continuous.

[LD] this does not work the power button will not turn off
[LD] apparently this is a prominent problem with this unit
[LD] I was on the phone with your customer support and I was told there is no fix and the machine is only designed to last 6 months what's up with that?
[George] Okay,
[LD] I'm now reading all over the net that Lexmark is not standing behind these machines at all
[LD] I'm going to post what I was just told
[LD] hello?
[George] Okay, karyn.
[George] Have you connect the power cable directly to the wall outlet
[LD] yes I have done that
[George] please try connecting to different out let and check whether power button turn on and off
[LD] I have connected, reconnected, rebooted and reinstalled
[LD] it will not
[LD] you may want to read this information there's all information all over the internet about this piece of junk machine
[LD] are you unaware of the problem this machine presents?
[George] Please let me know when did you buy this printer?
[LD] about 6 months ago
[LD] I am told it is out of warranty
[LD] and I have NO intention of paying $100 to get this fixed
[LD] nor do I have intention of EVER purchasing another Lexmark machine
[George] I apologize for the inconvenience that may have caused to you.
[LD] it has caused great inconvenience
[LD] again
[LD] so now I have no printer and I will be responsible to purchase a new one when I just made this purchase 6 months ago.
[LD] someone should close Lexmark down they are entirely irresponsible as a company
[George] Unfortunately this appears to be a hardware failure and our records indicate that your printer is out of warranty.
Although we will not be able to provide service, I do have another option for you. Because we appreciate your business and want to reward you for being a loyal Lexmark customer, I can offer you 20\% discount
[LD] 20\% off a DEFECTIVE PIECE OF CRAP is 80\% more of my money than you will ever see again
[LD] I have every intention of copying this message and posting it all over the internet
[LD] THEN I have every intention of contacting EVERYONE who sells Lexmark and telling them NOT to do business with you any longer because they are selling JUNK
[LD] Then I intend to contact the BBB along with the thousands of other people who got scammed by you people and filing as many documents as I can so they eventually put you out of business
[LD] this has to be some sort of joke it really does
[LD] and then to put someone on a technical chat that has NO CLUE as to the problems the machine presents is worse than the problem itself This company should not even be in business
[LD] I will make a point to purchase a new printer today. It will NOT be a lexmark nor will I ever use your products ever again at home or in my business. I will make it a point to contact everyone I know and let them know about the cheap junk that this company is marketing and to beware of anything you sell
[LD] Thank you for not responding, you are simply confirming that I and hundreds of others are correct
[LD] Have a nice day.
[George] I apologize for the inconvenience that may have caused to you.
[LD] nice answer, lol
[LD] nothing compared to the inconvenience and loss of business this will cause YOU.
[LD] I just posted this to the message boards.
[LD] enjoy your day.

There was a very simple way to do this, I'm thinking possibly there were two versions of this machine. A simple piece of tape over the "button", "Switch" whatever you want to call it, solved the problem in 10 seconds. I had taken the entire machine apart, was looking for the gray/white piece(nowhere to be found) and tried connecting the grey piece of wire, all with no luck. Simply putting a small piece of black electrical tape over the tiny button solved the problem immediately.

I put the machine back together and started printing again.

What a shame Lexmark takes so little responsibility for their errors. This is a nice machine....sadly I'm sure there are many that were tossed when a simple fix was all that was needed.

Thanks for all the info here, you were all wonderful.

I also have this printer and I utilized it at work. I had the exact same problem. I did an e-chat with the company: (John Doe] I had checked with my resources, I am really sorry to say, the hardware on the printer is defective. So you cant use the printer, but not to worry, if it is under warranty, then I will replace the printer with "Free shipment". [ME] Thank you. One more this an inherent problem with this particular printer?
[John Doe] No, this will not happen. But it will happen very rarely.
This conversation was on January 26. I was told I would receive my replacement in 3-5 working days. After four more phone calls and requesting to speak to a manager, to whom I indicated that if I did not receive restitution this time, I would call and chat with the host on line of the popular television shopping channel I purchased it from, I received a replacement printer X3550 today.

Same issue, only the small micro pivot points on the nylon switch seem to have sheered off somehow, rendering it unable to snap back on the switch mount. It was fun taking the printer apart to get to this conclusion.

I was tempted to say we get what we pay for .. since this was on the very low end of the printer/scanner combo spectrum, but that this could have happened while simply lifting the cover to change a cartridge is sign of an amazingly poor design regardless of cost. I have had to tape mine over to get it functional again.

thank you so much this saved me from buying a new printer. for all of you that have this problem it is not hard to fix and I found that if you shimmy nicely on the scanner part it comes off the printer completely and you don't have to take anything apart just work from the back of the printer. thanks again you are a life saver.

Great site!

Thanks for the info! Got this piece of junk from a friend who had gotten a replacement from Lexmark. So now I have a printer.

I wonder how long time it will be until my the new one my friend got will break down.

Once again Thank you all, especially Rob M. Cheers.

thank you very much for solving my problem with lexmark x3470. I not believe that a think of that type can happen. Why so much poverty in your design?

We just fixed ours too!!! Thanks for all the instructions. We are only on our 3rd cartridge and this time it gave us the COVER OPEN error too! So thanks to searching the internet and this website with pictures, we were able to fix it. No waiting for LEXMARK to help us, especially on a 3 day weekend!!! Thanks again!!!!

Thanks so much. Managed to fix my printer too using these instructions. Suggest take the advice to tape the lever down in closed mode once it's been re-attached. No sooner had I fixed it the first time then it fell off again! Taped it down now. IT WON'T HAPPEN AGAIN. As for Lexmark, it won't happen again either. So annoying.

Thank you so much Rob I just fixed mine with your instruction, but I didn't have to take off the scanner (mostly because I couldn't figure out how to get the connectors disconnected). BTW I did this alone and I'm only 12.

Thanks for this writeup. The lexmark site wasn't very helpful other than to tell me what the problem was. Anyway after a little surgery my printer is back up & running like a champ.

You'll remember some time ago I wrote how Lexmark had looked after me with my x3470 printer. Well unfortunately when I put in a new No 1 cartridge I got the dreaded cover open message.

I asked to speak to a manager, the switch girl put me through I stated my case and drew their attention to this page. they undertook to speak to one of their engineers and would contact me back.
After roughly three days I was called by one of the engineers who, after our conversation said, look I will send you out a x3550 a much better printer.
I thought that as he was in a giving mood I would ask for new cartridges foe the replacement as I had paid round $32 for the No1 cartridge that would be of no use.
To top it all off , within three days I now have a substantially more upmarket printer delivered to my door freight free.

So perhaps if you are like me who can't see to do the fix that you use, perhaps it would be O.K. to try my approach.

Thank you for your post about the fixing the printer. Your methods were extremely descriptive and knowledgeable. Whomever designed that little arms for LEXMARK needs to be drawn and quartered. Thanks for the post and I am glad my printer works again.

Thank you Rob - you are a genious. Not only was I lucky enough to pick the right website for helpful information, but while my boss was fixing this wonderful piece of office equipment, I read all your messages outloud. There is nothing like spending part of an afternoon at work laughing, instead of being frustrated because you have a broken printer. Thanks Again!

Re: Cover Open message. I found the white lever, which has 2 bumps on the inside of the slit end. The problem is that the microswitch also has 2 bumps - not 2 holes. I understand that the bump/hole idea is for pivoting. So that is one problem. Then, shouldn't there be some kind of spring? Once the arm that is part of the removed scanner activates the white lever, the white lever will stay down. Lastly, the very body of the micro switch gets in the way, ie., part of the micro switch ought to be able to pass thru the slit during pivoting, which is impossible. I think I will have to resort to the taping solution.

I had the same issue; everything worked great until trying to get the nylon lever arm back on; took me about 10 tries. It has to be at a slight angle. Also, make sure to put the cables back in before putting the top on; much easier. Thanks for all the help; it works!

it has pictures.

The lever cap is facing up and pointing toward you. The lever sticks out farther than I thought it would.

And for all the twelve year olds, maybe it was easier for a twelve year olds b/c they have small hands. There is no way my husband could fix this. What a design flaw! This printer should have been recalled!

Brilliant! Thank you so very much for this. What an annoyance this problem was but since it is my first printer and I inherited it I am happy to have one finally AND working!

I was fortunate enough to have those tiny surgeon fingers; all I did was remove the grey paper feed tray from the back of it, shine light through the front of it and place the piece onto my left index finger with my right hand to guide it into place. Not too bad!

Just called Lexmark Canada 1 800 663 7662 spoke to customer service and got no satisfaction so i politely asked to speak to a manager, i explained the issue to the manager and told her the internet was full of people complaining of this issue, she said that Lexmark is fully aware of this problem and it is not fixable (ha ha)and if i would provide her with my name, address and serial # from printer she would be happy to ship me a replacement free of charge.
My printer was 17 mths old so i am not sure if they will replace ALL printers regardless of age or if there is a time limit, just remember be polite and if they offer you a free printer thank them, i intend to call the manager when i recieve my printer and thank her again, you attract more bees with honey than with vinegar

Thanks to Rob I fixed the cover open problem but after printin several pages with no problem the printer said CLEAR CARRIER JAM so I looked inside and the clear plastic strip that I guess the ink carrier rides on has come off and the ink carrier just jams hard in both directions. Anyone know how I can fix this?

So the irony: A few days ago I was complaining about loaning my printer/scanner out to someone because I didn't want them to break it - I rely on the scanner more than anything.
As soon as I get it back...I break it this way. Hah.

Thanks for the instructions, got it all fixed up! I was confused on how to put the white part on and I kept trying to look up the correct way, but finally I gave up and shoved it in. Snapped right in place! Printer is working great!

Thank you for providing the info on this fix, after disconnecting ribbon and fine cables was able to wiggle scanner free. The white lever fell out when I shook it upside down and after a few attempts managed to click it back in place, without even using a screwdriver!

If anyone is still out there...

I'm having the same issues, however I graduated from the "cover open" error to the blank display, won't turn off prob... I popped it open and my lever was fine, but I don't get the audible "click" when I move the switch... any thoughts how to replace or bypass it?

I just repaired my printer on my own with the fantastic help of the online tecknician. A little lever arm on a switch under the cover had come loose and fell to the bottom. Had to remove cover and scanner to access fallen piece and replace little plastic arm on small button switch located behind the cartridge when cartdridge is in middle of printer.

Wow, finally I was able to get the "Cover Open" error to disappear. I haven't printed or scanned anything since but the printer it has no more errors so far. I appreciate everyone's comments and pictures here and I know how important the details might be. So here's what I learned after a day of trial and error:

- After you remove the purple kickstand, scanner body, and the grey layer, the white flat ribbon can be carefully pulled out from the circuitboard side. But I didn't try to remove the colored electrical wires, you can just get someone to hold the (partially decapitated) scanner body upright while you work.

- You just need to get a clear vertical view of the circuitboard from the back side where the lever should go.

- The first time I took the lever out from the bottom and put it where it was supposed to go, the printer gave me a very strange phantom paper jam error. There was no paper anywhere near the printer. So I found this video for that:
So I tweaked the lever position from up to down...

- The second time, however, it gave me the 'Cover Open' error again. So I guess the sensor screwed up something else - and the lever arm was not completely snapped onto the black switch thingy.

- After disassembling and reassembling a couple times, I was able to 'snap' the white lever this time but it was a bit lower than I expected - it really does snap, even if it looks like the tiny inside arms are worn off on the white lever. That's what eventually should work.

- When putting everything back together, make sure not to get any ribbons or wires under the gray layer snap points.
Good luck!

Thank you OP! This is the second time I've had this issue and used this post. If I have it a third then I will glue the circuit closed!

Suggestion: Link this post to this printer's Wiki. Almost everyone who owns the x3470 is bound to have this happen someday.

Thank you for saving me $60!
