Replacing Consumables
Cautions When Replacing
Observe the following cautions when replacing.
This section explains how to replace consumable items.
Toner cartridges and image drums are consumables.
• Cautions When Replacing
Do not throw the toner or toner cartridge into a fire. The toner will scatter,
resulting in burns.
• Replacing the Toner Cartridge
• For K (black) Toner Cartridge Only
• For C (cyan), M (magenta), Y (yellow) Toner Cartridge
Do not store a toner cartridge in a location where it is exposed to open
flames. The toner may ignite, resulting in fire or burns.
• Replacing the Image Drum
• Replacing the Image Drum Only
Do not vacuum spilled toner with an electric vacuum cleaner. Vacuuming
spilled toner with an electric vacuum cleaner may result in ignition due to
sparks from electric contacts or other reasons. If toner spills on the floor or
other places, wipe the toner with a damp rag or other cloth.
• Replacing the Image Drum and Toner Cartridge at the Same Time
Some parts inside the machine become very hot. Do not touch the
locations around a "CAUTION HOT" label. Burns may result.
Keep toner cartridges out of the reach of children. If a child accidentally
swallows toner, immediately seek medical advice.
If you inhale toner, gargle with a large amount of water, and move to a
place with fresh air. Seek medical advice if necessary.
If toner lands on your hands or other areas of skin, wash thoroughly with
soap and water.
If toner gets into your eyes, immediately rinse with a large amount of
water. Seek medical advice if necessary.
- 117 -
7. Maintenance
Replacing the Toner Cartridge
This section describes how to recognize the replacement period of Toner Cartridges.
If you swallow toner, spit it out. Seek medical advice if necessary.
When the "[COLOR] Toner Low" message ("[COLOR]" indicates C (cyan), M (magenta), Y
(yellow) or K (black)) which appears on the display screen, prepare a replacement toner
cartridge.
When handling a paper jam or replacing toner cartridges, use care not to
let your clothes or hands get dirty with toner. If toner lands on your clothes,
wash with cold water. If toner gets hot by washing with hot water or other
methods, the toner will stain the fabric and become impossible to remove.
When the "[COLOR] Toner Empty" appears and printing is stopped, replace the toner
cartridge.
Do not disassemble the image drum or toner cartridge. You may inhale the
scattered toner, or the toner may land on your hands or clothes, making
them dirty.
• Even if the cyan (blue), magenta (red) or yellow toner cartridges run out, you can print in black and white by
selecting [Monochrome] or [Grayscale]. However, please replace the toner cartridge quickly after it runs out, as not
doing so may cause the image drum to be damaged.
Store used toner cartridges by putting them into a bag while using care not
to scatter the toner.
• Have a new toner cartridge ready, as the print quality declines after more than one year following breaking the seal.
• If you replace the toner cartridge/image drum while it is being used, the amount of toner used will not be counted
normally.
• Use Oki Data genuine consumables to ensure optimum performance of the products.
• By opening and closing the front cover after the message "Color toner has run out" is displayed, you are able to print.
However further printing operations will not be possible after that. Please replace the toner cartridge as failure to do
so may damage the image drum.
• Charges for services for problems caused by the use of consumables other than Oki data genuine consumables are
incurred, regardless of the warranty or in the maintenance contract. (Although the use of non-genuine consumables
does not always result in problems, use extra care when using them.)
• Toner powder may spill if you remove a toner cartridge before the toner runs out.

Replacing the Image Drum
This section describes how to recognize the replacement period of an image drum, and how
to replace the image drum.
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 front cover cannot be closed if the output tray is not closed securely.
13
Please recycle toner cartridges.
• 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 image drum. Replace the image drum with
a new one.
• If you have to dispose of used toner cartridges, put them into polyethylene bags or other container, and be sure to
follow the regulations or instructions of your local government.
• Though opening and closing the front cover 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 [Admin Setup] > [Panel Setup] > [Near Life Status] is set to [Disable], the "[COLOR] Image Drum Near Life"
message does not appear.

• 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.
• Charges for services for problems caused by the use of consumables other than Oki data genuine consumables are
incurred, regardless of the warranty or in the maintenance contract. (Although use of non-genuine consumables does
not always result in problems, use extra care when using them.)

Replacing Maintenance Units
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.
This section explains how to replace maintenance units.
A fuser unit and a belt unit are maintenance parts.
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).
• Replacing the Belt Unit
• Replacing the Fuser Unit
• 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.)

Replacing the Fuser Unit
• The front cover cannot be closed if the output tray is not closed securely.
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.
14
• The actual number of pages you can print with the fuser unit depends on how you use it.
Please recycle belt unit.
• 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.)
• If you must dispose of a belt unit, put it in a plastic bag or similar container and dispose of it in accordance with
your municipality's ordinances or guidelines.
• When the [Admin Setup] > [Panel Setup] > [Near Life Status] is set to [Disable], the [Fuser Unit Near Life] message
