TROUBLESHOOTING AND ROUTINE MAINTENANCE

Replacing the Drum Unit
The DCP uses a drum unit to create the print images on paper. If the LCD shows
CHANGE DRUM SOON, the drum unit is near the end of its life. Purchase a
new drum unit to replace the current one.
Even if the LCD shows CHANGE DRUM SOON, you may be able to continue
to print without replacing 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 printer when you replace the drum unit.
Caution
■ When removing the drum unit, handle it carefully because it contains toner.
When you replace the drum unit, you should clean the machine.
■
Wait to unpack the drum unit until immediately before installing it into the machine.
If an unpacked drum unit is subjected to excessive direct sunlight or room light,
the unit may be damaged.
■ Handle the toner cartridge and the drum unit carefully because they contain
toner. If toner scatters and your hands or clothes get dirty, immediately wipe or
wash with cold water.
For best performance, use only a genuine Brother toner cartridge. The product
should be used only in a clean, dust-free environment with adequate ventilation.
WARNING
Just after you have used the DCP, some internal parts of the machine are
extremely HOT! So please be careful.
Follow these steps to replace the drum unit:
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 toner that you use and the number of pages per print
job, etc. The drum life is estimated at approximately 20,000 pages at 20 pages per
job and 8,000 pages at 1 page per job. 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.
