The installation of this smart chip is required for a refilled EPSON C13S05125 or C13S05129 cartridge to function properly. The chip is already included in our EPSON C3800 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. The chip's slide-in design makes for an easy installation.
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 (9000 pages at 5% page coverage).
