Printing is possible, but the image drum of
State of this machine
the displayed color is approaching the end of
its service life.
About 1,500 pages can be printed from when the time for replacement is approaching to when the time for
replacement has arrived.
 Printing quality will decline after the image drum stays unpacked for one year or longer. Therefore, prepare a new
image drum.
 Because the image drum (green part) can easily get damaged, handle with adequate care.
 Do not expose the image drum to direct sunlight or strong light (About 1,500 lux or above). Do not leave it uncovered
for more than 5 minutes even under room lighting.
 Use genuine OKI consumables for optimum performance.
 Failures caused by using non-genuine consumables may void the warranty or maintenance contract. (The use of
non-genuine consumables will not necessarily cause failures, but please fully take notice of such usage.)
 Replace the image drum immediately when a message indicating replacement of the image drum is displayed and
printing has stopped.
If you repeatedly open and close the front cover so that you can continue printing temporarily, a failure may be caused
or the print quality may be degraded.
In addition, after a certain period of time, printing will be disabled even if you open and close the front cover. (The
printable period of time varies with the usage condition.)
 If [Admin Setup] - [Panel Setup] - [Near Life Status] is set to [Disable], a message indicating the time for replacement
will not be displayed.
 You can change the timing for displaying a message indicating the time for replacement of the image drum. The
factory default value is [1500].
This timing can be set from [Admin Setup] - [Others Setup] - [Near Life Setup] - [Drum Near Life Timing] on the
operator panel.
The setting range is from 500 to 5,000 (in increments of 500).
