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 a used one,
the message window may not to be cleared or the toner level may not be displayed accurately.
- 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 °F (35 °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 Car-
tridge, 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.
Guidance for recovering used Toner Cartridge
- Put the used Toner Cartridge in a bag, place the bag in the box in which the Toner Cartridge was in-
cluded at the time of purchase, then send the box to us. Securely seal the bag and box with tape, being
careful of the toner in the Toner Cartridge. The recovered Toner Cartridge and Imaging Unit are recycled.
