WHAT IS A TONER CHIP?

Laser printers/copiers use toner cartridges that have chips installed on them. When the printer/copier runs out of toner, the chip recognizes the low toner level and sends a warning message to the printer. Many people prefer to refill the existing cartridge instead of buying a new. In that case, after you refill the cartridge, you must replace the old toner chip with a new one in order to increase again the level of counter.
