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
2 hours or longer without opening the protective bag 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 cartridge away from equipment that generates
magnetic fields, such as LCD displays and computers.
• A toner cartridge is a magnetic product. Keep the toner cartridge
away from products that may be damaged by magnetism, such
as a floppy disk or disk drive. This may lead to damage to data.

<On>
The machine continues printing the received fax if the toner
cartridge is not replaced. Note that the output may not be clear, as
subtle details such as thin lines and light colors may not be clearly
reproduced, due to a small amount of toner remaining inside the
toner cartridge. Plus, the data is deleted once it has been printed.
