Reinstall the drum unit and close the
front cover.
Replacing the Drum Unit
The MFC uses a drum unit to create print images on paper. If the LCD shows
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 LCD 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 appears), then the drum unit should be replaced. You should
clean the MFC when you replace the drum unit. (See page 21-18.)
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.
WARNING
Just after you have used the MFC, some
internal parts of the MFC are extremely
HOT! So please be careful.
The drum unit is a consumable item, and it is necessary to replace it periodically.
There are many factors that determine the actual drum life, such as temperature,
humidity, type of paper and how much toner you use for the number of pages per print
job. The estimated drum life is up to 20,000 pages. The actual number of pages your
drum will print may be significantly less than these estimates. Because we have no
control over the many factors that determine the actual drum life, we cannot
guarantee a minimum number of pages that will be printed by your drum.
HOT!
