which is in inside of the toner cartridge. 
•   Avoid locations subject to high temperature, high humidity, or  rapid changes in temperature. 
•   Do not expose the toner cartridge to direct sunlight or bright  light for more than five minutes. 
•   Store the toner cartridge in its protective bag. Do not open  the bag until you are ready to install the toner cartridge in the 
machine. 
•   Keep the protective bag for the toner cartridge. They are  required when transporting the machine such as during 
relocation. 
•   Do not store the toner cartridge in a salty atmosphere or where  there are corrosive gases such as from aerosol sprays.

scattering, and then dispose of the toner cartridge according to 
local regulations.
