Replacing the Belt Unit

Life Span of Belt Unit
When the "Belt Unit Near Life" message
appears on the display screen, prepare a
replacement belt unit. You can keep printing
approximately 2000 pages until the next
message appears.
When the "Change Belt Unit" message
appears, replace the belt unit.
The life expectancy of the belt unit is
approximately 80,000 pages for A4 simplex
printing (three pages per job).
Note
● The actual number of pages you can print with the belt
unit depends on how you use it.
Note
● Though opening and closing the output tray may extend
the life of the belt unit somewhat, you should replace it
soon after the "Change Belt Unit" is displayed to prevent
malfunction.
● If you replace the belt unit, use it until the end of its

life will not be correctly displayed.
