Compatible inkjet cartridges are another economical option. These are
original, new ink jet cartridges that have not been remanufactured, but
instead, are produced by a company other than the printer manufacturer.
These cartridges can be purchased at lower prices than their brand name
counterparts, and then refilled. There are patents
protecting some brand name cartridges, and compatibles will not be
available for those model. However, suppliers of compatible inkjet
cartridges often offer brand name cartridges as well, usually at a
significant discount. Compatible EPSON cartridges cannot be refilled
with much success. They have a very porous sponge in the cartridge which
fills with air as the ink leaves. You need to use a vacuum pump to
displace the air when trying to refill the cartridge. Often a refill kit
is not sold if a compatible cartridge is available.
Compatible inkjet cartridges vary greatly in quality. Look for a company that
manufactures their cartridges using the same ISO standards as brand name
manufacturers. A “no questions asked” return policy is a good
indication that the company stands behind the quality of their
cartridges. Suppliers who are upfront that compatible cartridges have
not yet been successfully produced for all inkjet printers are likely to
provide you with the best quality and guarantee for your money. Finally,
if you are worried about a generic ink jet cartridge voiding the
guarantee on your printer warranty, or even ruining the printer
completely, learning more about how an inkjet printer works will help
you allay your fears.
