Everprint CHIP-KYO-TK-3190 is a chip for a Kyocera TK-3190 cartridge. It is intended for cartridge servicing when a replacement chip is needed.
The listing specifies a 25,000-page (25K) print resource. A cartridge chip stores status information such as page count and toner use, helping the printer identify the cartridge and track its use.
Replacing the chip can allow a refilled cartridge to be used again. This makes the part useful when restoring a cartridge for further printing.
