Using Dmax Ink Will Not Void Your Warranty
Printer Manufacturers, like Epson and Canon, cannot legally stop you from using third party inks like Dmax. Customer support at Epson and Canon may try to convince you that third party inks violate their warranty. This is misleading. Refusing your warranty for using third party ink is in violation of the Magnuson-Moss Warranty Act of 1975. If you are having trouble with Canon or Epson customer support calmly and confidently tell them that refusing to honor the warranty due to third party inks is in violation of the Magnuson-Moss Warranty Act of 1975.
The Magnuson-Moss Warranty Act
The Magnuson-Moss Warranty Act is a law passed to protect consumers in 1975. It states: “No warrantor of a consumer product may condition his written or implied warranty of such product on the consumer’s using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade or corporate name” (15 U.S.C.A. 2302)
In the case of printers and ink this means that Canon and Epson cannot tie the warranty of the printer itself to a requirement for you to use their other products and services like ink and software. You bought the printer and the warranty is for the printer. It is legally reasonable for you to use a third party ink like Dmax and Canon and Epson cannot tell you otherwise.
Power to the printers!
Highlighted in Green: “Epson cannot guarantee the quality or reliability of third-party ink.” Epson is not saying you cannot use third-party ink.
