The Magnuson-Moss Warranty Act.

Compatible Cartridges Will NOT Void Your Printer’s Warranty

Your right to buy and use alternative printer ink cartridges is protected by the Magnuson-Moss Warranty Act.
A common fear of consumers thinking about purchasing compatible or remanufactured ink cartridges is that their use will render the printer warranty void. Many brands of printers include messages that pop up after insertion of a remanufactured cartridge claiming that your warranty may become void, though these messages are primarily there to encourage loyalty to the original manufacturer’s brand (OEM) cartridges rather than stating the legal implications of using alternative cartridges.

The truth is that the use of remanufactured printer cartridges will NOT void your printer warranty. In fact, it would be illegal for printer companies to revoke warranty based on type of cartridge used. As a consumer you have the right of choice when it comes with refilling the ink for your printer, which means you are not obligated only to use OEM cartridges.
The Magnuson-Moss Warranty Act Protects Consumers Against Warranty Voiding

Legally, the Magnuson-Moss Warranty Act is a law that states that “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”.

How The Act Protects Consumers' Right To Purchase Alternatives

The only exception to this rule is when the product would not function correctly without the product or service of the manufacturer, which is not the case with printer cartridges, or if a Commission finds that it would be in the public’s interest to include related products or services into the warranty, which is also not the case with printer cartridges.
In fact it is within the public’s interest to provide a range of purchase options. Not only does this leave the consumer with much better value for money (where they can sometimes cost 50% less than the OEM cartridge), but it is a much better option for a wide range of reasons. The environment benefits from the fact that more cartridges are being reused instead of sent to landfill, as well as the fact that fewer cartridges need to be produced from scratch. These reasons reduce the carbon footprint of the consumer choosing such cartridges.

In short you should not be put off by any warnings from a printer manufacturer that the use of remanufactured cartridges will void your warranty. When printer manufacturers warn against factors such as inferior ink quality or poor yield of the cartridge they are usually attempting to keep customers loyal to their own product, therefore making more money. In actual fact, it is perfectly legal and possible to find great quality remanufactured cartridges for any printer model.
