and the drum unit
When the display shows the following, replace the toner 
cartridge.
TONER LOW
TONER EMPTY
To check the drum life and quality, please print the printer 
test list (page 64). 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-FAT88) and drum unit 
(Model No. KX-FAD89). See page 10 for accessory 
information.
To maintain print quality and machine life, we 
recommend you to clean slots and openings (page 6) 
and the inside of the unit (page 62) when replacing the 
toner cartridge and/or drum unit.

unit or degradation of print quality which may 
occur from the use of a non-Panasonic toner

protection bag for a long time. It will decrease the 
toner life.

cartridge, shake it vertically more than 5 times.
