The Everprint CHIP-KYO-TK-4145-B is a compatible cartridge chip for the black Kyocera TK-4145 laser cartridge, listed for the TASKalfa 2020. It is intended for cartridge replacement or refurbishment, where a replacement chip helps the device recognize and track the cartridge.
The chip communicates cartridge resource information to the printer, allowing it to count printed pages. The listing gives a stated capacity of 16K pages. This is a compatible Everprint component, rather than an original Kyocera chip.
Package contents: 1 chip.
