• For C (cyan), M (magenta), Y (yellow) Toner Cartridge
- Replacing the Image Drum
• Replacing the Image Drum Only
- Replacing the Image Drum and Toner Cartridge at the Same Time

1. Maintenance

Cautions When Replacing

Observe the following cautions when replacing.

	Do not throw the toner or toner cartridge into a fire. The toner will scatter, resulting in burns.
	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.
	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.

CAUTION
	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.
	If you swallow toner, spit it out. Seek medical advice if necessary.
	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.
	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.
	Store used toner cartridges by putting them into a bag while using care not to scatter the toner.

!

• 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 the use of non-genuine consumables does not always result in problems, use extra care when using them.)

Replacing the Toner Cartridge

This section describes how to recognize the replacement period of Toner Cartridges.

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 the "[COLOR] Toner Empty" appears and printing is stopped, replace the toner cartridge.

• 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.

!

- 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.
• 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.
• Toner powder may spill if you remove a loner 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 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.
• 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.

Replacing the Image Drum Only

Replacing the Image Drum and Toner Cartridge at the Same Time

Replacing the Image Drum Only

This section describes how to replace the image drum when you want to continue using the toner cartridge.

!

• 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 the Fuser Unit

• Maintenance

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.

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).

!

• 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.)
• When the [Admin Setup] > [Panel Setup] > [Near Life Status] is set to [Disable], the [Belt Unit Near Life] message does not appear.
• 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 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.

[NO TEXT]

- You can change the setting for displaying the "Belt Unit Near Life" message. Set from [Admin Setup] > [Others Setup] > [Near Life Setup] > [Belt Near Life Timing]. Available values are from 500 to 5,000 (in 500 increments).

Prepare a replacement belt 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.
