HP stated on their official website regarding printer using non-original toner cartridge:
"The use of a non-HP or refilled cartridge does not affect either the HP Limited Warranty to the end-user customer or any HP support contract with the end-user customer for the printer. However, if printer or print head failure or damage is attributable to the use of a non-HP or refilled cartridge, HP will charge its standard time and materials charges to service the printer for the particular failure or damage or for the cost to replace the print head. For HP ink cartridges and supplies and HP LaserJet supplies, this HP Limited Warranty does not apply to products that, in addition to other exclusions described in this HP Limited Warranty, have been refilled, refurbished, remanufactured, or tampered with in any way. This HP Limited Warranty pertains to HP ink cartridges, print heads, or HP LaserJet print cartridges when used in its designated HP or authorized original equipment manufacturer (OEM) printing device."
