Replacing the Drum Unit
The machine uses a drum unit to create print images on paper. If the
screen displays CHANGE DRUM SOON, the drum unit is near the end of
its life and it is time to purchase a new one.
Even if the display shows CHANGE DRUM 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 CHANGE DRUM SOON is shown), then the drum unit
should be replaced. You should clean the machine when you replace the
drum unit. (See page 11-14.)
Caution
When removing the drum unit, handle it carefully because it contains
toner. If toner scatters and your hands or clothes get dirty, immediately
wipe or wash with cold water.
