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.

Please follow the steps below on how to replace ink cartridge on the Lexmark X5495 printer:

1. Make sure the printer is on.
2. Lift the scanner unit. The print cartridge carrier moves and stops at the loading position, unless the printer is busy.
3. Press down on the cartridge carrier latch to raise the cartridge carrier lid.
4. Remove the used print cartridge.

Sometimes the ink cartridge carrier won't automatically move to its loading position even when the printer is on and the cover is open. Follow the steps below:

1. Unplug the printer from the power source.

2. With the cover open, hold the solid white strip that connects from the carrier assembly to the ink cartridge carrier and gently slide the cartridge carrier to the center of the printer.

3. Remove the used cartridges.

4. Load the new cartridges. Close the cover.

5. Plug the printer back to the power source.

It could be that one of your cartridge is not properly seated in the cartridge carrier or one of the cartridges is faulty.
Follow the steps below to fix this problem:

1. Open the printer cover.
2. Remove both cartridges from the printer.
3. Close the printer cover.
4. Unplug and replug the printer printer into the power source to reset it.
5. When the printer turns on, reinsert one cartridge first. Close the printer cover.
6. Check for any errors.
7. If no errors open the printer cover again and reinsert the other cartridge.
8. Replace whichever cartridge is causing the error to appear.

Note: It is recommended to use only genuine Lexmark cartridges.

In some cases, the ink cartridge carrier won't position itself in the middle even when the printer is on and the cover is open. Just unplug the printer from the power source. With the cover open, hold the white tape in the middle inside the printer. The other end of it is connected to the carrier. Gently slide the carrier to the center. Load the cartridges. Close the cover. Plug the printer back to power source. Hope this helps.
