The HP Color Laserjet CP2025 10.100 Supply Memory Error is normally the result of a chip error on one of the cartridges. First you should check that each cartridge has a chip, it could have just fallen out. If you have old cartridges still, you could replace the chips on your faulty cartridges with the chips from the old ones. The cartridge will give inaccurate toner levels as a result, but atleast it will remove the error message.
On some rare occasions, pressing the 'OK' button when the error appears on the LCD screen allows you to bypass the message.
