Without a smart chip installed, your printer's toner level indicator will always read "low" even after the cartridge has been refilled. However, it will still print.
Purchasing this chip will allow your printer to display its toner level accurately and will 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 (2300 pages at 5% page coverage).
This smart chip will reset the toner level indicator on the following cartridges: CANON Type 120, 320, 720
