HP 722C cartrige light flash will not print.
Maybe there are dirty contacts in the cartrdige holder. Take a brush (like a toothbrush) and clean the contacts of the cartridge holder.
Note that even new cartrdiges can be damaged. If you put a clogged cartrdige the printer refuse to print and the orange led is blinking.
