The HP C6656A black cartridge is currently HP’s most common cartridge, and probably the most common on the market today. It currently works in about 70 different inkjet printers, a number that other manufacturers cannot keep with simply because they do not have the huge number of models that HP does. By comparison, the next most common cartridge would probably be the Canon BCI-3e black, which works in about 30 fewer machines. Because it is such a common and popular product, there are a number of options:

HP OEM 56 - this is the cartridge that comes with your printer and the one you will find in stores. It is usually $20 everywhere you go, which doesn’t seem like much but in reality is significantly more than the cartridge that it replaced, the 51645A. The HP 45 is $30 but contains 42ml of ink, while the C6656 only has 19ml. So it works out to be about 70 cents per milliliter for the 51645 ink and 95 cents for the C6656 ink. On the other hand, the HP 56 is a bargain compared to newer black HP cartridges like the HP 94 (retails at $20 for 11ml) or the HP 21 ($15 for 5ml).

Remanufactured C6656 - this is a product that we, along with a growing number of other companies, sell at a price that is lower than HP’s retail price. Not speaking for everyone, but a typical remanufactured cartridge (like ours) is a 56 cartridge that has been cleaned, refilled to capacity and then fitted with a new print head. So it is basically a new cartridge with a recycled casing, which doesn’t really have anything to do with the performance of the cartridge.

Refill kits - available for almost all common HP inkjet cartridges, refilling is the option that saves you the most money. We sell a refill kit that is $10.99 and gives you two refills, so basically it works out to be $5.50 per refill. If you bought two new HP cartridges from the store, it would be about $40. Also, this cartridge is good for refilling because black cartridges are always easier to refill (simply because it is one color, not three) and because the 56 has a nice, basic design.

Refilling service - this is where you can have someone refill your cartridge for you. In our case, the service we offer is Renew. You purchase the service, receive a mailer and then send away your empty cartridge and it comes back to you refilled. This is a service for people who like to the idea of recycling and reusing their cartridges, but don’t have the time or the desire to refill their own cartridges.

More and more people are becoming aware that you don’t just have to throw away your empty HP cartridge and go to the store and buy another one at full price. There are a number of options, and even if none of these interest you, you can still recycle your cartridges just for the sake of recycling.
