CHAPTER FIFTEEN
Drum Life Considerations for Your Brother
Fax Machine
Your Brother fax machine uses a drum and toner assembly for document
printing. The toner life is directly dependent upon the amount of black
printing on the printed pages. The drum will last for 77 hours of
continuous printing time, which in normal use will be up to 20,000 A4
sized pages. Maintaining quality print during this period will depend on
factors such as the number of pages printed per day, time between print
jobs (and/or fax receptions), the quality of the printing paper and the
environment in which the machine is used.
The drum unit (DR-6000) is a consumable and to maintain an acceptable
printing quality it should be replaced at the end of it’s 20,000 A4 page or
77 hours life. Printing quality is a subjective issue and the drum should
be replaced at a time when the printing quality becomes unacceptable to
the user in relation to the documents being printed. The print quality will
deteriorate over time and replacing the drum will return the printing
quality to its optimum level. In order to maintain optimum print quality,
we also recommend that the drum is replaced after 18 months service.
To assist you, the machine will advise when approximately 5-15% of the
drum life remains by showing the message “CHANGE DRUM SOON
on the display.
This indication takes the number of pages printed and the total printing
time into consideration. When the message appears we advise that a new
drum be obtained for replacement at a convenient future time.

We emphasise that even if the drum life remaining indicates 0%, you
only need to replace the drum if the print quality is unacceptable. By
using a drum past the 0% indication no damage will be caused to the
machine and whilst the print quality remains acceptable then the drum
may be used beyond its designed life.
