The number of times you can refill an ink cartridge depends on how well it was taken care of between refills as well as on the quality of the inkjet print head. Until it wears out, you can continue to perform a printer ink cartridge refill. But as a rule of thumb, you can do it up to seven times before it becomes unusable.
