MAINTENANCE
1
Open the front cover and pull out the drum unit.
Place the drum unit on a drop cloth or large piece of disposable paper to avoid spilling and
scattering the toner.
2
Hold down the lock lever on the right and pull the toner cartridge out of the drum unit assembly.
3
Unpack the new toner cartridge. Place the used toner cartridge into the aluminium bag and
discard it according to local regulations.
Handle the toner cartridge carefully. If toner scatters on your hands or
clothes, immediately wipe it off or wash them with cold water.
• Wait to unpack the toner cartridge until immediately before you install it
into the machine. If a toner cartridge is left unpacked for a long period of
time, the toner life is shortened.
