Replacing the Belt Unit
When the "Belt Unit Near Life" message appears on the display screen, prepare a
replacement belt unit. You can keep printing approximately 2,000 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 80,000 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.
• "Install New Belt Unit" may be displayed without "Belt Unit Near Life" being displayed. Replace the belt unit in this
case, too.
• When "Change Belt Unit" is displayed and printing is stopped, quickly replace with a new fuser unit. Although printing
is resumed by opening and closing the front cover, this may cause a malfunction or cause print quality to deteriorate.
Also, after a fixed time has elapsed, printing is no longer possible even by opening and closing the front cover. (The
fixed time that printing is possible differs according to the operating status.)
• When the [Admin Setup] > [Panel Setup] > [Near Life Status] is set to [Disable], the [Belt Unit Near Life] message
does not appear.
• Use extra care when handling the image drum (the green cylinder), because it is fragile.
• 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 [Admin Setup] > [Others
Setup] > [Near Life Setup] > [Belt Near Life Timing]. Available values are from 500 to 5,000 (in 500 increments).
