Replacing the drum units
IMPORTANT
• While removing the drum unit, handle it
carefully because it may contain toner. If
toner scatters on your hands or clothes,
wipe or wash it off with cold water at once.
• Every time you replace the drum unit,
clean the inside of the machine (see
Cleaning and Checking the machine
on page 103).
• DO NOT unpack the new drum unit until
you are ready to install it. Exposure to
direct sunlight (or room light for long
periods of time) may damage the drum
unit.
