Take a look at this and see if this is why:

Open the front door, as when you have a paper jam.
On the left is about a 3" curved white plastic swing hing guide piece, slotted in the middle.
On the metal wall to the left of it is a tab bent out to fit into this groove. If the Tab is not fully in the groove, it will prevent the front door from "fully" closing on this side, preventing it from actuating the switch mentioned by others.

A simple fix that solved it for my OKI C5650 "310/311:Cover Open"

Hello,

had the same problem. It is easily fixed.
On my printer a OKI C5750 is had to main covers, at the front (which you have to open to fix a paper jam) and a big cover on top (which you need to open to replace toners).
On the left is a piece of plastic which (when closed) presses on a switch.
When you open both covers, and close the top one, you can see it on the left when it comes down.

You can easily remove the error (only for a brief moment) by prushing the shining metal switch to the back.

But the problem is that one of the rollers is in a wrong position.
So just take a flat screwdriver and press on the bottom roller, and it will click and the problem will be gone when you close the covers.

310-330 EROR CODE

Whenr. posting error codes, it is best to indicate device, brand, model number. If this is a OKI laser printer, the error code 310 may be indicating a top cover is open. On a canon laser printer, the code 330 may indicate a need to replace or repair a power supply. Codes vary by brand. You might try googling the code plus the brand and possibly the model. "error code 310 brand model"

Canon mp470 printer says cover is open when it isn't.

If the cover is closed and you have found the switch and tested it ok, try to unplug the printer and restart.

When i try to print on my Lexmark 2300 it keeps saying scanner unit is open, but it isn't. I've turned it off and on opened and closed the unit but this hasn't helped

It could be the cartridges in the carrier. Please follow the steps below to identify and 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.

3. Remove both cartridges from the carrier.

4. Close the printer cover.

5. Unplug and re-plug the printer into the power outlet to reset it.

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. You may also try to insert a different known working cartridge to determine if the cartridge you are currently using is faulty.



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

My lexmark Z2300 will not feed the paper. The roller in the back (by the paper) does not move. I just changed the black ink. It has also said communication problem when I tried to print. NOW when you...

Disconnect the printer from your pc. Remove the sheets of paper from the feeder. Open the printer cover and remove the cartridges. While the cover is open, check the cartridge area and make sure there are no obstructions in the cartridge carrier's path. Check for any loose transparent strip (encoder strip) behind the carrier. If everything looks fine, close the cover. Unplug and replug the printer into the power source to reset it. When the printer turns on, reinsert both cartridges. Close the cover. Reconnect printer to the computer. Try to print again.

I got a message to replace drum cartridge

The drum cartridge catches waste toner, so the problem isn't that it's empty -- the problem is that it's full.

You can buy a replacement here:

http://accessories.us.dell.com/sna/PopupProductDetail.aspx?c=us&l=en&cs=bsdv&sku=310-5732

This part costs $169, and should be good for over 10,000 pages of normal printing.

Manufacturer Part# : M5065
Dell Part# : 310-5732



Itcomes with very detailed instructions on how to remove the oldcartridge and install the new one. Very easy, but there's no way aroundthe price tag.

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!
