All of our compatible & remanufactured cartridges are warranted to be free from defects in material, workmanship and performance for a period of 1 year from the date of purchase. If, at any time during the warranty period, our cartridges fail to perform according to the aforementioned, we will replace the cartridge or credit the full purchase price. All returned cartridges are weighed and compared against the full and empty weights and if a cartridge is found to be empty then no refund or free replacement will be given. Our warranty does not cover damage due to improper installation, or modification or abuse of the cartridge. We will not be liable for incidental or consequential damages of any kind. If the Laser Printer, Copier or MFP device is found to have been damaged due to the use of our compatible or remanufactured toner cartridges, then we will pay for the repair or replacement of the machine. We reserve the right to hire an independent technician to determine the cause of any reported machine damage.
