4-2 Care and Maintenance

Replacing Consumables

When a consumable needs to be replaced, the printer stops printing and displays an

error message indicating which consumable should be replaced. The following table

shows the life expectancy of each consumable.

External factors can affect the average yield of consumables. Some of these factors are:

Humidity

Temperature

Type of paper

Run length of jobs

Adequate ventilation around equipment

Image coverage on page

Print Utilization - if less than 80%, projected consumable life may become shorter

Print density

Consumable Average Life Expectancy

Toner 36,000 images (5% coverage

)

Developer Mix 480,000 images (600,000 drum rotations)

Drum Unit 400,000 images (500,000 drum rotations)

Fuser 1,600,000 images

Fuser Cleaning Web 320,000 images

Toner Collector Bottle Every other refill of the toner

NOTE:

“Image” means paper size of Letter/A4 LEF. Other page sizes will have

“images” based on Length of Form/8.5”.

Coverage is calculated per printed sheet and is defined as the ratio of area with toner to the total area of

the sheet. Toner usage is based on 5% coverage when the toner density level is set to the default value.

The following items affect toner coverage: the printed image content, the paper used, and the condition

and calibration of the printer. Actual toner usage may vary due to these factors.
