Maintenance
• 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.
• Do not remove the toner cartridge from the machine
unnecessarily.
• Print quality may deteriorate if the drum surface is exposed to
light or is damaged.
• Always hold the toner cartridge by its handle to avoid touching
the drum.
• Do not place the toner cartridge in an upright or an upside
down position. If the toner is kept upright or upside down, the
toner will solidify and may not return to its original condition
even if it is shaken.
• When disposing of a used toner cartridge, place the toner
container into its protective bag to prevent the toner from
scattering, and then dispose of the toner cartridge according to
local regulations.
