The installation of this smart chip is required for a refilled LEXMARK C540A1CG, C540H1CG, C540H2CG, C544X1CG, or C544X2CG cartridge to function properly. The chip is already included in our LEXMARK C540/C543/C544/C546/X543/X544/X546/X548 refill kit.
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 kit (2000 pages at 5% coverage).
