cartridge 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 93) and refer to page 96
for information on the drum life. If printing quality
is still poor or “REPLACE DRUM” appears on the
display, 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-FA85X) and drum
unit (Model No. KX-FA86X). See page 12 for
accessory information.
To maintain print quality and machine life, we
recommend you to clean slots and openings
(page 5) and the inside of the unit (page 88, 92)
when replacing the toner cartridge and/or drum
unit.
Caution:
L 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.
L The drum unit contains a photosensitive
drum. Exposing it to light may damage the
drum.
Once you have opened the protection
bag:
– Do not expose the drum unit to light for
more than 5 minutes.
– Do not touch or scratch the black drum
surface.
– Do not place the drum unit near dust or
dirt, or in a high humidity area.
– Do not expose the drum unit to direct
sunlight.
L Do not turn the power switch OFF. Loss of
fax documents in memory may occur.
L Do not leave the toner cartridge out of the
protection bag for a long time. It will
decrease the toner life.
L Do not add toner to the toner cartridge.
1 Before opening the protection bag of the new
toner cartridge, shake it vertically more than
5 times.
2 Remove the new toner cartridge from the
protection bag.
3 Lift the cover release lever (1) and open the
top cover (2).
Important:
L Close the multi-purpose input tray (3)
before opening the top cover.
