Most printers will issue a warning or prompt when you need to replace the toner cartridge. Once the consumables indicator light on the printer changes color, it is a signal to replace the toner cartridge.

The toner cartridge will have a label indicating the number of printable pages. The estimated replacement time also will be determined based on the amount of printing paper used. A chip counter on the selenium drum counts the number of printing times. Based on the last time the toner cartridge was replaced, you can estimate how long and how much paper needs to be used to determine the approximate replacement time.
