Precautions when installing toner cartridges
The position of the toner cartridges in the printer is determined
by the toner color. Install the toner cartridges in the slots that have
labels of the same color.
Do not leave the front cover open for a long time with
the toner cartridges installed.
This may result in a deterioration in print quality.
After replacing toner cartridges
To maintain image quality, it is recommended to perform
automatic gradation adjustment.

Miscellaneous precautions
• Do not expose the toner cartridge to direct sunlight or strong
light.
• Never disassemble or modify it.
• Condensation may form in and on the toner cartridge if it is
brought into an environment that exposes it to sudden changes
in temperature and/or humidity. If you move the toner cartridge
to a location that is warmer or has higher humidity, leave the
cartridge in the new location for two hours or longer without
opening the protective bag to allow it to adjust to the new
temperature.

a toner cartridge. However, the printed documents may be light

the documents are printed out, so you cannot print the same
