Note
● The actual number of pages you can print with the fuser
unit depends on how you use it.
Note
● Though opening and closing the top cover may extend
the life of the fuser unit somewhat, you should replace it
soon after "Change Fuser Unit" is displayed to prevent
malfunction.
● If you replace the fuser unit, use it until the end of its
useable life. If you remove the fuser unit and install and
use another one before its usable life has expired, the use
life will not be correctly displayed.
● When the <ENTER> button > [Admin Setup] >
[System Setup] > [Near Life Status] is set to
[Disable], the [Fuser Unit Near Life] message does not
appear.
