Replacing Maintenance Parts
This section describes how to replace maintenance parts.
• Replacing the Belt Unit
• Replacing the Fuser Unit
When the "Belt Unit Near Life" message appears on the display screen, prepare a
replacement belt unit. You can keep printing approximately 1,000 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 60,000 pages for A4 simplex printing
(three pages per job).
• The actual number of pages you can print with the belt unit depends on how you use it.
• 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 usable life. If you remove the belt unit and install and use another
one before its usable life has expired, the use life will not be correctly displayed.
• When the [Device Settings] > [Admin Setup] > [Manage Unit] > [System Setup] > [Near Life LED] is set to [Disable]
on the touch panel, the [Belt Unit Near Life] message does not appear.
• The image drum (the green tube) is very delicate. Handle it carefully.
• Do not expose the image drum to direct sunlight or very bright interior light (approximately more than 1,500 lux). Even
under the normal interior light, do not leave it for more than 5 minutes.
You can change the setting for displaying the "Belt Unit Near Life" message. Set from [Device Settings] > [Admin
Setup] > [User Install] > [Belt Near Life Timing] on the touch panel. Available values are from 500 to 3,000 (in 500
increments).
