When the display shows the following, replace the toner cartridge.
To check the drum life and quality, please print the printer test list. If printing quality is still poor, replace the toner cartridge and
drum unit. To ensure that the unit operates properly, we recommend the use of Panasonic toner cartridge (Model No. KX-

To maintain print quality and machine life, we recommend you to clean slots and openings and the inside of the unit when replacing
the toner cartridge and/or drum unit.
Caution:
• • • • We cannot be responsible for any damage to the unit or degradation of print quality which may occur from the use
of a non-Panasonic toner cartridge and drum unit.
