NOTICE
Thoroughly read all the precautions and warning labels, and be sure to follow their instructions. These labels
are provided inside the door of this machine or inside the machine.
1.1 Before getting started
Carefully handle this machine so that you can use it for an extended period of time. A failure caused by in-

If dust or slips of paper are left inside or outside this machine, it may reduce printing quality. We recommend
that you periodically clean this machine. Follow the guideline shown below.
-When cleaning the inside of this machine or clearing a paper jam, exercise care not to touch around the
Fusing Unit because internal components such as the Fusing Unit may be hot.

2.2.1 Replacing a Toner Cartridge
Handling a Toner Cartridge
When handling a Toner Cartridge, be careful of the following.
-This machine supports four Toner Cartridges: black, yellow, magenta, and cyan. When handling a
Toner Cartridge, take care not to spill toner on this machine or your hand.
-Replace a Toner Cartridge with an unused product. If a Toner Cartridge is replaced with the used one,
the message window is not cleared.
-Do not forcibly open the Toner Cartridge. If toner has leaked, avoid toner inhaling or skin contact as
much as possible.
-If your clothes or hand has been stained with toner, wash it off with soap and water.
-If you have inhaled toner, move to a fresh air place, then gargle well with a large amount of water. If you
have had a symptom such as a cough, see your doctor.
-If any toner enters your eyes, immediately wash them with running water for 15 minutes or more. If pain
persists, see your doctor.
-If you have drunk toner, wash your mouth out well, then drink one or two glasses of water. See your
doctor, if necessary.
-Keep Toner Cartridge out of reach of babies and children.
-When handling a Toner Cartridge, do not touch the printed circuit board installed on the Toner Car-
tridge.

Storing Toner Cartridges
Store Toner Cartridge as shown below.
-Do not open the protection bag before installing a Toner Cartridge.
-Store Toner Cartridges in a cold dark place, away from direct sunlight.
-Store Toner Cartridges in a place in which the temperature is 95 degrees F (35 degrees C) or less and
the humidity is 85% or less with no dew condensation. If a Toner Cartridge is moved from a cold place
to a warm place with high humidity, a dew may form. which may affect printing quality. Before using a
Toner Cartridge, leave it for approximately one hour to adjust to the ambient environment.
-Keep Toner Cartridges horizontal. Do not place a Toner Cartridge in the reverse direction from that
specified. Doing so may cause toner in a Toner Cartridge to become hard or uneven.
-Do not touch salty air or corrosive gases such as aerosol.
Tips
Guidance for recovering used Toner Cartridge

careful of the toner in the Toner Cartridge. The recovered Toner Cartridge and Imaging Unit are re-
cycled.
