I'm getting an error message on my HP Deskjet 2775 that says 'Foreign Ink Cartridge'. What does this mean and how do I fix it?

The 'Foreign Ink Cartridge' error indicates that the printer doesn't recognize the ink cartridge as a genuine HP cartridge. This can happen with refilled or third-party cartridges. While some users have success overriding this error (methods vary and may void warranty), the most reliable solution is to use genuine HP ink cartridges specifically designed for the Deskjet 2775. The printer is designed to work optimally with HP ink.
