Drum End Soon
The machine uses a drum unit to create print
images on paper. If the LCD shows
Drum End Soon, the drum unit is near the
end of its life and it is time to buy a new one.
Even if the LCD shows Drum End Soon,
you may be able to continue printing without
having to replace the drum unit for a while.
However, if there is a noticeable deterioration
in the output print quality (even before
Drum End Soon appears), then the drum
unit should be replaced. You should clean the
machine when you replace the drum unit.
(See Cleaning the laser scanner windows on
page 147.)
CAUTION
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.
