Won usage of a ink jet refill kit or new compatible replacement print cartridge void my printers warranty?
• No, it is actually a violation of the Mugnusson-Moss Warranty Improvement Act (Title 15 Commerce and Trade, Chapter 50 – 2302) for any manufacturer to require the use of its proprietary (and spendy!) supplies for fulfillment of the printer’s warranty. It is illegal for the manufacturer to void the warranty simply because you used third-party supplies. The manufacturers know this, though it does not keep them or their employees from making empty threats and misleading statements.
