Brother MFC7650MC - Manual (Page 174)

Replacing the Drum Unit
The MFC uses a drum unit to create the print images on paper. If the display shows
CHANGE DRUM SOON, it indicates the drum unit is nearly at the end of its life. We
rftmmmend you prepare 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. 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.
WARNING
When removing the drum unit, handle carefully because it contains
toner.
You should clean the MFC when you replace the drum unit. See pages
165-167.
NOTE: The drum unit is a consumable, and it is necessary to replace it periodically. The
drum unit is rated at approximately 20,000 pages. 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 bfe is
estimated at approximately 20,000 pages at 20 page per job and 8,000 pages at 1
page per job. The actual number ofpages your drum will print maybe significantly
less than these estimates. Because we have no cuiiLi ol 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.
Follow these .steps to replace the drum unit'
1) Open the top cover.
2) Remove the old drum unit. (See
