Will using a non-HP or refilled ink cartridge void my warranty on the HP Deskjet 2300?
Using a non-HP or refilled cartridge does not directly void the warranty or any HP support contract. 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 specific failure or damage.
