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

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.
