THE LAW IS ON YOUR SIDE
Printer owners have the right to choose the imaging supplies that offer them the best value, regardless of brand or printer model. This right is legally protected under the Magnuson-Moss Warranty Improvement Act, which makes it unlawful for any printer OEM, technician, or service professional to void a printer warranty if aftermarket consumables are used.
