When to refill?
You have to refill you cartridges before ink in your cartridge completely runs out. Once the cartridge is empty, the ink starts to dry and may clog the nozzle.

How many times I can refill?
It depends on the cartridge condition. You can refill until your cartridges wears out. In general, you can refill 8 to 10 times with the same cartridges.

Refilling will void the OEM's warranty on my printer?
Don't be afraid to use your consumer rights. It is illegal for a printer manufacturer to require you to use any particular brand of supplies. An OEM (Original Equipment Manufacturer) cannot avoid your warranty unless they can conclusively prove that other brands of supplies will damage the machine. To enforce a policy such as this is in direct violation of the Sherman & Clayton Antitrust Acts. Don't be afraid to show this statement to any service person or OEM representative who threatens your right to choose your own supply sources.
