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.
Other precautions
Do not expose the toner cartridges to direct sunlight or strong light.
Do not attempt to disassemble or modify the toner cartridges.
Condensation (water droplets on the inside or outside) may form on the toner cartridges when they are brought into
an environment with a sudden change in temperature or humidity.
When moving a new toner cartridge to a location with change in temperature, leave the cartridge in the protective
bag at the new location for two or more hours to allow it to adjust to the new temperature.
Do not leave the front cover open for a long time with the toner cartridges installed.
Keep the toner cartridges away from products that generate magnetic waves, such as a computer or computer
display.
