Precautions for Handling the Toner Cartridge
The toner cartridge is constructed from precision mechanical parts. Handling the 
cartridge roughly can damage it or cause deterioration of printing quality. Whenever 
you are installing or removing toner cartridges, take care of the following handling 
precautions.
WARNING
Do not put spent toner cartridges into a fire. Any toner remaining in the toner 
cartridge may ignite, causing burns or fire.
CAUTION
Be careful to avoid staining your clothes or hands with toner. If you do get any 
toner on your clothes or hands, wash it off immediately with cold water. If you 
rinse using hot water the toner may become fixed, creating a stain that cannot 
be removed.
