Replacing the Fuser Unit

When the "Fuser Unit Near Life" message appears on the display screen, prepare a
replacement fuser unit. You can keep printing approximately 2,500 pages until the next
message appears.
When the "Change Fuser Unit" message appears, replace the fuser unit.
When using A4 paper (simplex printing), the estimated replacement cycle of a fuser unit is
approximately 100,000 pages. This estimation assumes the standard use condition (three
pages are printed at a time). Printing one page at a time reduces the fuser unit lifetime
approximately by half.
• The actual number of pages you can print with the fuser unit depends on how you use it.
• When "Change Fuser 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 [Fuser Unit Near Life] message
does not appear.
• 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 "Fuser Unit Near Life" message. Set from [Admin Setup] > [Others
Setup] > [Near Life Setup] > [Fuser Near Life Timing]. Available values are from 500 to 5,000 (in 500 increments).
