We recommend that you place the toner
cartridges on a clean, flat surface with a
piece of disposable paper underneath it in
case you accidentally spill or scatter toner.
DO NOT put a toner cartridge into a fire. It
could explode, resulting in injuries.
Handle the toner cartridges carefully. If
toner scatters on your hands or clothes,
wipe or wash it off with cold water at once.
To avoid print quality problems, DO NOT
touch the shaded parts shown in the
illustrations.
