Wrong cartridge Printer not functioning. Error message = 'Wrong Cartridge." I've taken the cartridge out and replaced it and the message does not go away.

make sure all in correct. Clean sensors and cartridges then delete and reload driver. if this does not correct issue, then you have a faulty cartridge

I logged into Lexmark's web site and checked their printer support page. It said that if you get error message 1203 your ink cartridge has leaked fluid. In order to find the right cartridge, do the following. Remove both ink cartridges, put in one, turn off the printer, turn it back on and if you get the message 1203 that's the cartridge with the problem. I did not get that message. I turned off the printer, put in the other cartridge, and turned it back on. Sure enough, I got the 1203 message again. (I had cleaned the wrong cartridge before). I removed the leaky cartridge, cleaneded it (making sure I did not leave any residue) and put it back in the printer. It worked!

No way around the problem. Replace the cartridge.

It's a bad cartridge.

its not a true fix but I had the same issue. I turned off printer and slightly moved the paper thickness lever over a few inches. I turned it back on and the cartridge error was off. I do get a pop up from my printer program on the computer every time I initiate a print job asking to correct the lever, I click OK and it prints. I know its aRube Goldberg fix but I need this printer every day for work and for now it works.

Doubled check the cartridge numbers and that they match what is on the printer. If no match get correct ones.

Hi, remvoe the black ink cartridge , dip the cartridge in luke warm water for 30 secs , clean the cartridge and unplug the power adapter from the printer , wait for a minute and then reconnect it back , put back the cartridge and then look for the error msg , if it stil displays the same error then its an issue with the cartridge and needs to be replaced..
Do lemme know if it helps..
Thanks

If you are absolutely sure that cartridge is installed correctly, the contacts where cartridge may be dirty. Clean gently with soft lint free cloth with small amount of rubbing alcohol and retry. If problem persists the contacts may have been damaged.

Issue: ERROR LCD: PUT IN CARTRIDGE
Solution: Press ON/OFF switch to reset the multifunction device

Reset the device when it is not functioning properly. If the device is not functioning properly or to clear memory, reset it.

1. On the operator panel, press and hold the <ON/OFF> button for one second. (The display will go blank.)
   
   
2. Wait approximately ten seconds and then press the <ON/OFF> button again.
   
   
3. Wait until the device has completed its cycling process before submitting another job request.

The Print Head might be the fault of that,try replacing the print head and see if that helps
