Now, what can be done if you really want to refill your rock? The best thing to do would be to get some purging fluid or you can make your own version of 50% water and 50% Ammonia. Inject fluid into cartridge, as much as you can get in. Let it sit for a day or two. Then suck out as much as you can with your injector.

Refill in normal manner but don't expect best results because it is impossible to remove all of purge fluid. Your prints might be a little washed out until fluid mixes with ink. If you're persistent you could possibly restore it to 100%.

Congratulations, you just refilled a rock! :-)

You don't need a lot of expensive tools to get started. A couple refill kits will pay for themselves rather quickly. If you specialize in a few types of cartridges you won't have to buy a lot of supplies. Popular cartridges like HP C6578 and HP 51645A, HP 6656, HP 6657, Lexmark 12A1970 and 12A1980, 10N0016 and 10N0026.

You will also need boxes and cartridge clips or just use print head sealing tape. These are pretty cheap and you can find them on internet.

If you have a printer that fits a popular cartridge you can use it to test your cartridges before selling them. You can buy printers on eBay for pennies on dollar for testing machines. Don't forget other auctions like Yahoo, Ubid and Amazon for buying printers. Actually you might get a better deal buying a printer on smaller auctions.

Price your cartridges about 25% below retail or use prices from our web site. There's plenty of business to go around so what are you waiting for?
