Just an FYI on inkjet printer warranties! (and this actually came from someone at Epson!) There is a law that says a company CAN NOT void an inkjet printer   warranty for using ink other than their brand name cartridge! They said that to do that, the ink would have to be provided by the printer company FREE OF CHARGE! That is the only way that a company can make that kind of stipulation in a warranty situation. Think about it, the guy I spoke to said that if you think about the car companies, they GIVE you the part as part of the warranty if there is a problem, that is why they say that a warranty can be voided if you buy NAPA parts, etc instead of theirs! There is no way that an inkjet printer company can void your warranty for not using their ink, unless they want to send you all of your ink free! I would definitely be MORE than willing to use their brand name ink if that was the case! LOL!!! Here is part of the Magnuson-Moss Warranty Act that the Epson rep was talking about :

"Under the Magnuson-Moss Warranty Act and general principles of the Federal Trade Commission Act, a manufacturer may not require the use of any brand of ink (or any other article) unless the manufacturer provides the item free of charge under the terms of the warranty if you are told that only the original equipment ink will not void the warranty, you should request that the original equipment ink be supplied free of charge."

This is some other things I found on this:

"Being forced by a manufacturer to use OEM brand supplies may also be a violation of the Sherman and Clayton Antitrust Acts which prohibit "tying" sales."

"IBM VS. THE UNITED STATES, a case brought before the U.S. Supreme Court, set the precedence. The high court ruled that companies which engage in the practice of requiring or intimidating their customers into purchasing supplies or replacement parts from them exclusively creates a "tying agreement," which as found to be in violation of the Antitrust Laws." I have actually been using a replacement ink in my Epson 900 since this past July - never had a problem with it - it is ISO certified (which means it MEETS or EXCEEDS Epson's requirements for their ink), and - this is the BEST part - - - it is about 1/3 to 1/4 as much as if I bought the Epson brand.

The funny thing is, it is made in the same place as the Epson ink, and when you open the box, has the same foil package, and the cartridge looks the same too (even down to the yellow and white tape and blue and white label)!! HMMM - makes a person wonder, doesn't it???
