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 4200 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.
