brother mfc won't recognize cartridge

Problem Brother MFC-230C won't recognize new black ink cartridge. Seems the remanufactured cartridges appear to be empty. It seems there are light sensors in the printer that sense the cartridge is empty even when it is full. The solution is to put tape on the back of the ink jet cartridge. The danger of such a procedure is that the cartridge could be totally empty and it will burn out the printhead before you realize it.
