Replacing the Image Drum
This section describes how to recognize the replacement period of an image drum, and how
to replace the image drum.
Before Replacing
Replacing the Image Drum Only
Before Replacing
When the "[COLOR] Image Drum Near Life" message appears on the display screen, prepare
a replacement image drum. If you continue printing, the message "[COLOR] Image Drum
Life" will be displayed and printing will stop.
When the "Please install new Image Drum Unit." message is displayed and printing stops,
replace the image drum.
When using A4 paper (simplex printing), the estimated replacement cycle of an image drum
is approximately 30,000 pages. This estimation assumes the standard use condition (three
pages are printed at a time). Printing one page at a time reduces the drum lifetime
approximately by half.
The actual number of printed pages may be less than half the above estimation depending
on the printing conditions.
Note
The actual number of pages you can print with the image drum depends on how you use the
machine. It may be less than half the above estimation depending on the printing
conditions.
Printing quality may deteriorate after 1 year following the unpacking of the toner cartridge.
Replace the toner cartridge with a new one.
Though opening and closing the output tray may extend the life of an image drum for a
while, it is recommended to replace it soon after the "Install New image drum" is displayed.
When the [Device Setting] > [Admin Setup] > [Management] > [System Setup] > [Near Life
Status] is set to [Disable], the "[COLOR] Image Drum Near Life" message does not appear.
Replacing the Image Drum Only
This section describes how to replace the image drum when you want to continue using the
toner cartridge.
Note
If you use a new image drum with the toner cartridges currently in use, the remaining
amount indication of the toner cartridges will not display correctly. The messages "[COLOR]
Image Drum Near Life" or "[COLOR] Image Drum Life" may also be displayed soon after
replacement.
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 strong light (approximately 1,500 lux or
more). Even under room lighting, do not leave the image drum for 5 minutes or more.
Use Oki Data genuine consumables to ensure optimum performance of the products.
