Unsupported cartridge error

I have an X5495 Lexmark and have recently been getting this **** "unsupported cartridge" rubbish. OS is XP SP2.

My history with this printer has been:
-when new, the printer worked fine until I needed to replace the original ink tanks. I refilled them, but could not get the printer functional again....nil print at all. After much frustration, I was informed by a little birdie that the cartridges that originally come with the printer will not work if refilled. Great. They are one use only.
-replaced with genuine high yield tanks. Then worked fine. Refilled once, possibly twice with suitable non genuine ink. Still working fine.
-once black ink tank ran low this time, refilled it and symptoms of no print from Word docs, not all parts of a web page would print. Surprisingly, photos off hard disc print ok.(??????)
-replaced black with genuine tank and colour with remanufactured tank. Error message of "unsupported tank". Now no print at all.
-left new genuine black cartridge in and refitted genuine colour cartridge that I have previously refilled.
-all print now ok.....finally.

Maybe they have a copy limit or the integrated print head in the black has crapped itself????????

During this process, I have uninstalled and reinstalled the driver several times.
I have found that it has to be COMPLETELY uninstalled. Using the Lexmark uninstall function does not remove all parts of the software (Lexmark toolbar for one). If the software is not completely uninstalled, you will get a spurious unrelated and rubbish pop up that installation cannot continue because of "insufficient processor speed" with a spurious set of numbers after it. This message bears no relation to the solution.

I have found that you need to search and delete ALL Lexmark files that you can find after the uninstall. I have also deleted entries from registry.....1 entry only from memory (be CAREFUL with registry). Then reboot system.

The driver should then reinstall correctly and fully.

Why do they make it so damn hard? Don't think I'll buy a Lexmark next time.......

I THINK IT BEST TO CHANGE PRINTER BRANDS FOR SOMEONE THAT WILL HELP ME

Nope, the chip on the ink is what tells it if it's a genuine HP, Lexmark etc... if it doesn't read it you basically have to change it. Try tricking it, take out the cartridge, turn it off then back on without the cartridge, it's going to ask for it put it it and close it. Also, try cleaning the contacts ( shiny copper on the toner.
