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.

“Image” means paper size of Letter/A4 LEF. Other page sizes will have “images” based on Length of Form/8.5”.

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

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

1Coverage 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.
