Everprint CHIP-CAN-EXV49-Y is a yellow cartridge chip for the Canon IR C3330, listed for the C-EXV49-Y, 19K cartridge. It is a replacement component for the cartridge’s electronic identification and status tracking.
The chip stores cartridge information such as page count and toner use. When the cartridge reaches its recorded limit, fitting a new chip can allow a refilled cartridge to be used again. This makes it useful when servicing a compatible cartridge rather than replacing the complete cartridge each time.
