Toner cartridge

Service life of the toner cartridge

The number of printable pages of a toner cartridge is based on the condition that continuous printing is done on 1-sided A4 paper according to the data of "ISO/IEC 19752". The number of printable pages may vary with the actual printing conditions (*).
* Printing conditions: content of printed documents, printer driver settings, user's operating environment, OS environment, operational adjustments during power ON/OFF or cover opening/closing, etc.

To check the remaining toner amount, select [Menus] - [Configuration] - [Supplies Life] - [Toner] on the operator panel.
