The chip on the cartridge needs to be reset. You can find replacement chips on the internet but they cost about half as much as a new cartridge. Also, if you filled the cartridge incorrectly you can get air in the ink lines of your printer which will make it unable to print that color. Overall, I would recommend getting refills from Cartridge World. They always reset the chip, take care of the mess of filling for you, cost less than new cartridges, and are 100% guaranteed to work.

Under the cartridge is a black like pump - on a new cartridge this is hard and rests firmly on an area inside your printer. As you print, the pump becomes softer - this is how the printer determines it is empty. Once refilled, the pump does not get back to the original state. Open the bottom of the cartridge and put a firm solid piece of folded paper in there - make sure it is steady and re-close cartridge. It will now read as full but may also show full - judge ink levels by the quality of print. Also make sure chip has not expired.

Er, NO.
The answer to the above question is clearly misleading.
If you consult the documentation for your HP K5400, which can also be found online, you will find that the printer cartridge lights also blink when the print heads require replacing.
If you have replaced the cartridge and the light still flashes, this is the most common solution. Replace the print heads.
Unfortunately because the printer is badly designed, there is no way of indicating this, and you will have troubles if you attempt to get the HP Toolbox or any other diagnostic tools working.
Good luck!
