Once the head is failed or this error occurs, the chance of fixing it is slim to none. I'm really sorry if my solutions don't work. You should get a new printer because it has more life for head and other components than the current printer and you will get a fresh warranty, where repairing/replacing existing components doesn't give that. If the printer is more than 2 years old, then it is not worth replacing the head and components. I'm really sorry, this is something that we can't fix online if the above steps don't work for you.

If you have another cartridge there, then check with it. Turn off the printer for 20 minutes and also disconnect it from power. 90% of the time, the error indicates a hardware issue. The problem occurs when there is no ink flowing to the print-head to keep it cool or print, which can occur when a cartridge is run completely dry or no ink is flowing to the head.
The Canon B500 series error (including B504) is built-in protection to stop the print-head from overheating and burning itself.
