The Facts About Printer Warranties

The Magnuson-Moss Warranty Act of 1975 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.”

This means the OEM cannot, as a condition of the warranty, require the use of their cartridge.


HP Laser Printers
“Warranty does not apply to defects resulting from (a) improper or inadequate maintenance or calibration, (b) software, interfacing, parts or supplies not supplied by HP, (c) unauthorized modification or misuse, (d) operation outside of the published environmental specifications for the product, or (e) improper site preparation or maintenance.”

While using another brand of cartridge can not completely void your printer warranty, the printer maker does not have to repair damage that is caused by another brand of cartridge.

However, the remainder of the warranty still applies. Only damage that is specifically caused by use of another brand of cartridge is exempted.

The Federal Trade Commission requires that warranties be readily available to purchasers of items costing $15 or more. They may be provided with the item, or kept nearby where they are displayed.

Yet, few of us know the real terms of the warranties on anything we own.

The International Imaging Technology Council and its members want you to know about your printer warranty – especially as it may apply to toner cartridges.
