Does using a non-HP or refilled cartridge void the warranty on the HP OfficeJet Pro 7720?

Using a non-HP cartridge or a refilled cartridge does not affect either the warranty to the customer or any HP support contract with the customer. However, if printer failure or damage is attributable to the use of a non-HP, refilled, or expired ink cartridge, HP will charge its standard time and materials charges to service the printer for that particular failure or damage.
