The installation of this smart chip is required for a refilled DELL 331-7335 cartridge to function properly. The chip is already included in our DELL B1160/B1165 refill kits.
This chip allows your printer to display its toner level accurately and let you know when you are about to run of toner.
InkOwl smart chips are of high quality. They have been engineered to emulate the original chip's functionality. They are calibrated to the page yield of our toner kits (1500 pages at 5% page coverage).
This chip will only work on printers bought in North America.
