After changing cartridge the message "cover open"

Error: "Invalid Toner Cartridge"; Error: "Invalid Refill"; Message: "Change Cartridge"
Solution
One of these error messages may appear on the printer display immediately after or shortly after a new toner cartridge is installed into the printer. Note: This may not be specifically a toner cartridge problem; the error may be due to a stuck cover open switch on the printer.

To see if the cover open switch is the cause of this problem, open the top front cover and observe the message on the printer's display panel. The display should read Close Door or Insert Cartridge.


If this message is not displayed, the top cover open sensor and switch will need to be replaced. In addition, the printer may have damaged the new toner cartridge. If the cover open sensor is not operating properly, a new cartridge can be incorrectly flagged as a refilled cartridge by the printer. If this happens, the new cartridge will continue to cause an Invalid Refill or Invalid Cartridge error even if you try reinstalling it or installing it into another printer. If this should occur, please contact the point of purchase of the cartridge to find out how to get the cartridge replaced.

Caution: If the cover open sensor is not operating, do not install another new toner cartridge until you have completed the directions below. Inserting another new cartridge can cause that cartridge to stop working as well. Should this situation arise, please take the following actions:


Place the original working cartridge (the empty or near-empty one) back into the printer. This should clear the error message.

Turn the printer off. Doing this will disengage the cover open sensor.

With the printer switched off, open the top lid and remove the old toner cartridge.

Now replace the old cartridge with another new Lexmark toner cartridge.

Power the printer back on. The printer should now read this cartridge as a newly installed toner cartridge and the error should be cleared. The printer and toner cartridge should function properly now, but the top cover sensor on the printer will still need to be replaced.

If your printer is still under warranty or covered under a service contract, please contact Lexmark Technical Support or your service provider for further recommendations and instructions. Until you can get the cover open switch replaced, remember to have the printer powered off whenever you replace the toner cartridge.

If the top cover switch appears to be working fine, or if you have followed the above steps and your printer continues to post an Invalid Toner Cartridge or Invalid Refill error, make sure you are using a new original Lexmark toner cartridge. A toner cartridge remanufactured or refilled by a third party can cause this error.

To help identify a refilled cartridge, look for the yellow label attached to the toner drum and the body of the toner cartridge. If this is damaged or removed, the cartridge may have been refilled.

If you are using a third-party refilled or remanufactured toner cartridge, it is recommended that you install a new Lexmark brand toner cartridge. Lexmark cannot guarantee the compatibility of any third-party toner cartridges with our printers.

1 Switch on the Lexmark X83 printer.

2 Lift open the cartridge door at the front of the device, below the scanner unit. The printer automatically moves the cartridge carrier to the correct position.

3 Pull each ink cartridge toward you to unclasp it from the carrier. Lift the cartridge out of the cartridge carrier.

4 Clean the copper contacts on the bottom of each cartridge with a clean, dry lint-free cloth. Use a gentle, circular motion to clean the contacts.

5 Insert the ink cartridges back into the cartridge carrier. Push back firmly on each cartridge until it snaps into place.

6 Repeat each step in this procedure again. Close the cartridge door.

The clear/back option is usually reserved for resetting drum page counts. Resetting toner page counts is usually achieved by a flag gear on the left hand side of the cartridge that rotates and tags a micro-switch arm inside the printer when the cartridge is first installed. If the micro switch doesn't register, the cartridge count is not reset although the flag gear has rotated and will not do so again unless manually reset.

It could be that the cover sensor is stuck or could also be due to the cartridges in the printer. Please follow the steps below on how to identify and fix the problem:

1. Remove the sheets of paper from the feeder.
2. Open the printer cover and remove the cartridges.
3. Close the printer cover.
4. Re-brick your printer by pulling out power supply, black box where the power cord is plugged in at the back of the printer, and put it back after 30 seconds.
5. When the printer turns on, reinsert one cartridge first.
6. Close the printer cover and check for any errors.
7. Reinsert the other cartridge.
8. Replace whichever cartridge is causing the error to appear.
9. If no error appears, reload some sheets of paper and try to print a document again to verify that problem is fixed.

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

1. Remove a misfed document if the copier displays a message reading "Document Jam." Lift up the document feeder cover and turn the roller to remove an Exit Misfed document. Lower the document feeder back into place and feed the document through again. If the document is jammed on the Input side, open the cover and gently pull the misfed document to the right and out of the feeder.
   
2. Pull out the paper tray and lift the tray to release it from the copier if the copier displays a message reading "Paper Jam O." Remove the jammed document, and open and close the side panel of the copier to clear the error message.
   
3. Unplug the power cord and plug it back in again if the copier displays a message reading "Fuser Error, Open Heat Error, Heating Error and Overheat." If the problem persists, call for a service.
   
4. Remove the toner cartridge and shake it from side to side if the copier displays a message reading "No Developer Cartridge." If this does not do the trick, you may need to replace the cartridge. Pull the release latch to open the side cover, and open the front cover. Twist the cartridge locking-lever upwards and remove the toner cartridge. Insert the new cartridge and lock the lever into place. Shut the front cover and the side cover.
   
5. Power off the unit and power it on again if the copier displays a message reading "LSU Error." A problem has occurred with the Laser Scanning Unit. If the problem persists, call for a service.

Replace the toner: Always use the smart card provided with the new Print Cartridge when replacing the cartridge. The smart card contains the information necessary to reset the level of Toner. Replacing the cartridge without using the smart card may result in the consumable management system being inaccurate.

1. Insert the smart card provided with the new Print Cartridge into the smart card reader. A "Change Toner?" message will be displayed.
   
   
   
   
2. Press the [OK] button. An "Open Front Cover Replace Toner" message will be displayed.
3. Push on the left and right side of the Front Cover and simultaneously lower the cover.
   
   
   
   
   
   
4. Grasp the handle on the Print Cartridge, and then raise and remove the cartridge from the machine.
   
   
   
   
   
   
5. Unpack the new cartridge, and then insert the cartridge into the machine.
   
   
   
   
   
   
6. Close the Front Cover. A "Have You Changed the Toner?" message will be displayed.
   
   
   
   
7. Press the [OK] button. A "Please Wait" message will be displayed while the machine reads the smart card, and then a "New Toner Remove Card" message will be displayed.
8. Remove the smart card from the reader and dispose of the card as normal office waste.
   
   NOTE: If the smart card has been used with a previous installation of a Print Cartridge, a "Remove Card Already Used" message will be displayed. The smart card can only be used once. Make sure to use the card that came with the new cartridge.

It is probably best to replace cartridges individually as necessary. Let me explain. The printer display will tell you when a cartridge is "xx near empty" and when "xx empty" (where xx is the cartridge color).

1) Near Empty - you can continue to print. This message is to remind you to get a new "xx" cartridge and have it on hand.

Replacing the cartridge when "Near empty" will cause the machine to report "xx Empty" when it is not. It will not register that you have replaced it at "Near empty." Wait to replace the cartridge when you get the "xx empty" message.

2) XX Empty - you may not be able to continue printing. Replace cartridge "xx" now per your manual.

If you have replaced or reseated more than one cartridge, and you get the "no cartridge" error, you need to find out which one the machine "thinks" is problematic:

1) With the scanner cover open and locked in the "Up" position, the message may change to "Change cartridge, install xx" (xx refers to the color )

2) After changing the suspected cartridge and closing the scanner cover, be sure to notice the display. It will say, "Changed XX? 1. Yes 2. No" Press 1.

If all this explanation does not work, keep it in mind for next time. Brother says to unplug the machine for at least 10 seconds, then plug it in again. If the display shows the date and time, problem solved. If not, you may need to contact brother support.

Check that the contacts are clean. Also try another catridge. Even a new on can be bad...
