TROUBLESHOOTING AND MAINTENANCE
Replacing the Drum Unit
The fax machine uses a drum unit to create the print images on paper. If the
screen displays CHANGE DRUM SOON, the drum unit is nearly at the end
of its life. Purchase a new drum unit to replace the current one.
Even if the display 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 fax
machine when you replace the drum unit.
WARNING
When removing the drum unit, handle carefully because it contains toner.
When you replace the drum unit, you should clean the fax machine. (See
page 111.)
The drum unit is a consumable, 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.
For best performance, use only genuine Brother toner, and the product
should be used only in a clean, dust-free environment with adequate
ventilation.
