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:
n Humidity
n Temperature
n Type of paper
n Run length of jobs
n Adequate ventilation around equipment
n Image coverage on page
n Print Utilization - if less than 80%, projected consumable life may become shorter
n Print density
Consumable Average Life Expectancy
Toner 36,000 images (5% coverage 1 )
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.
