SAVE THESE INSTRUCTIONS
For best performance
Toner cartridge and drum unit
LWhen replacing the toner cartridge or drum unit, do 
not allow dust, water, or liquids to come in contact 
with the drum. This may affect print quality.
LFor optimal performance, genuine Panasonic toner 
cartridges and drum units are recommended. We 
cannot be responsible for problems that may be 
caused by a non-Panasonic toner cartridge or drum 
unit:
– Damage to the unit
– Poor print quality
– Improper operation
Toner cartridge
LDo not leave the toner cartridge out of the protection 
bag for a long time. It will decrease the toner life.
Drum unit
LRead the instructions on page 13 before you begin 
installation of the drum unit. After you have read 
them, open the drum unit protection bag. 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.
LTo extend the life of the drum unit, the unit should 
never be turned OFF immediately after printing. 
Leave the power turned ON for a minimum of 30 
minutes after printing.
Location
LTo avoid malfunction, do not position the unit near 
appliances such as TVs or speakers which generate 
an intense magnetic field.
Static electricity
LTo prevent static electricity damage to the interface 
connectors or other electrical components inside the 
unit, touch a grounded metal surface before touching 
the components.
Environment
LKeep the unit away from electrical noise generating 
devices, such as fluorescent lamps and motors.
LThe unit should be kept free from dust, high 
temperature and vibration.
LThe unit should not be exposed to direct sunlight.
LDo not place heavy objects on top of the unit.
LWhen you leave the unit unused for a long period of 
time, unplug this unit from the power outlet.
LThe unit should be kept away from heat sources such 
as heaters, kitchen stoves, etc. It should not be 
placed in rooms where the temperature is less than 
10 °C (50 °F) or greater than 32.5 °C (90.5 °F). Damp 
basements should also be avoided.
LIn the printing process, heat is used to fuse toner 
onto the page. As a result, it is normal for the 
machine to produce an odor during and shortly after 
printing. Be sure to use this unit in an area with 
proper ventilation.
LDo not cover slots or openings on the unit. Inspect 
the air circulation vents regularly and remove any 
dust build-up with a vacuum cleaner (1).
Routine care
LWipe the outer surface of the unit with a soft cloth. Do 
not use benzine, thinner, or any abrasive powder. If any toner comes into contact with your 
skin or clothing, wash the area thoroughly 
with cold water, then air dry. Do not use hot 
water or hair dryer. If there is skin irritation, 
seek immediate medical treatment.
If you inhale any toner, move to an area with 
fresh air and consult local medical 
personnel.
