Unpack the new toner cartridge. Gently
shake it from side to side several times
to distribute the toner evenly inside the
cartridge.
IMPORTANT
• Wait to unpack the new toner cartridge
until immediately before you put it in the
machine. If a toner cartridge is left
unpacked for a long time, the toner life will
be shortened.
• If an unpacked drum unit is put in direct
sunlight or room light, the unit may be
damaged.
CAUTION
HOT SURFACE
Put the toner cartridge in the drum unit
immediately after you have removed the
protective cover. To prevent any
degradation to the print quality, DO NOT
touch the shaded parts shown in the
illustrations.
