Maintenance

Cleaning the scan unit

Keeping the scan unit clean helps ensure the best possible copies. We 

suggest that you clean the scan unit at the start of each day and during the 

day, as needed.

1.

Slightly dampen a soft lint-free cloth or paper towel with water.

2.

Open the scanner lid.

3.

Wipe the surface of the scanner glass and DADF glass until it is clean 

and dry.

4.

Wipe the underside of the scanner lid and white sheet until it is clean 

and dry.

5.

Close the scanner lid.

MAINTAINING THE CARTRIDGE

Toner cartridge storage

To get the most from the toner cartridge, keep the following guidelines in 

mind:
•

Do not remove the toner cartridge from its package until ready for use. 

•

Do not refill the toner cartridge. The printer warranty does not cover 

damage caused by using a refilled cartridge.

•

Store toner cartridges in the same environment as your printer.

•

To prevent damage to the toner cartridge, do not expose it to light for 

more than a few minutes.

Expected cartridge life

The life of the toner cartridge yield depends on the amount of toner that print 

jobs require. The actual number may also be different depending on the 

print density of the pages you print on, and the number of pages may be 

affected by operating environment, printing interval, media type, and media 

size. If you print a lot of graphics, you may need to change the cartridge 

more often.

Redistributing toner

When a toner is low, faded or light areas may appear. It is possible that 

colored images may be printed with incorrect colors due to flawed mixing of 

toner colors when one of the colored toner cartridges is low on toner. You 

can temporarily improve print quality by redistributing the toner.
•

The toner-related message saying that the toner is low may appear on 

the display.

1.

Using the handle, completely open the front cover.

•

Do not touch the green surface, the OPC drum or the front of the 

toner cartridge, with your hands or any other material. Use the 

handle on each cartridge in order to avoid touching this area.

•

Be careful not to scratch the surface of the paper transfer belt.

•

If you leave the front cover open for more than a few minutes, the 

OPC drum can be exposed to light. This will cause damage to the 

OPC drum. Close the front cover should the installation need to 

be halted for any reason.
