Replacing The Fuser Unit - Oki MC853 User Manual

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.
The life expectancy of the fuser unit is up to 100,000 pages for A4 simplex printing.
Note
The actual number of pages you can print with the fuser unit depends on how you use it.
Though opening and closing the Output Tray 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 [Device Setting] > [Admin Setup] > [Management] > [System 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.
Memo
You can change the setting for displaying the "Fuser Unit Near Life" message. Set from [Device
Setting] > [Admin Setup] > [User Install] > [Fuser Near Life Timing]. Available values are from
500 to 5,000 (in 500 increaments).
