8.4 Replacing the toner 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 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.

Caution:

LWe 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.

LThe 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.

LDo not unplug the unit. Loss of fax documents in

memory may occur.

LDo not leave the toner cartridge out of the

protection bag for a long time. It will decrease the

toner life.

LDo not add toner to the toner cartridge.

1Before opening the protection bag of the new toner

cartridge, shake it vertically more than 5 times.

2Remove the new toner cartridge from the protection

bag. Peel off the seal (1) from the toner cartridge.

3Remove the handset and document stacker.

4Lift open the front cover (1), holding the dotted area

(2) on the right side.

5Remove the drum and toner unit (1) by holding the

two tabs.

LDo not touch the transfer roller (2).

LIf you replace the toner cartridge and the drum

unit at the same time, skip to step 9.

Caution:

The fuser unit (3) gets hot. Do not touch

it.
