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.
Table 4-1. Life of Consumables
Consumable Life Expectancy
Toner 54,000 images (5% coverage)
Developer Mix 800,000 rotations (640,000 images)
Fuser Cleaning Web 600,000 - 200,000 images
Fine Filter 2,000,000 images (5% coverage)
Toner Bag Exchange for every two toner supply
NOTE:
The projected life of the above consumables are based on 5% image
coverage, on Xerox 4024 letter size 20 lb paper, or 80% print utilization.
The actual point at which the supplies should be replaced will vary with
the type of materials you are pointing.
Waste materials should be disposed of under conditions which meet all
federal, state and local environmental regulations. Since regulations may
vary from one region to another, check with the agency that governs waste
disposal in your area for proper procedures.
The life expectancy of the consumables is calculated using the assumption
that 80% of drum rotations result in printed pages. This allows for the
extra rotations at the start and end of a printing cycle. Each rotation of the
drum results in wear because of the drum cleaning brush and the charge/
discharge cycles. If the jobs are short resulting in the printer stopping and
starting frequently, then the consumable lifetime of the drum will be lower.
The life of fuser cleaning web”600,000 images” is based on the following
conditions.
Stop frequency is once every 250 images, and web rolling-up interval is
once every 60 images.
The life of fuser cleaning web “200,000 images” is based on the following
conditions.
Stop frequency is once every 250 images, and web rolling-up interval is
once every 20 images.

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 (1.3 optical density for
solid black areas printed on Xerox 4024 paper). 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.
