The Magnuson-Moss Warranty Act, sometimes called the ‘lemon law’, is a law that was enacted in 1975 to protect consumers and the warranties on their products.
When buying a new printer, very often the warranty will make mention of using only Original Equipment Manufacturer (OEM) printer cartridges and that use of another type of printer cartridge will void the warranty. This is in fact not correct. The warranty is only voided should the cartridge itself cause the damage.
According to the Magnuson-Moss Warranty Act, a company is not allowed to hold you to ransom and force you into using only their brand of printer cartridges. In short, it is permissible to use the supplier and supplies of your choice.
