Using the Coverage Estimator

The Coverage Estimator provides you with an estimate of the percent coverage of cyan, magenta, yellow, and black toner on a page. These estimates are printed on the page.

To turn on the Coverage Estimator utility:

1Make sure your printer is on.

2Press on the operator panel.

3Press until Settings appears, and then press .

4Press until Utilities Menu appears, and then press .

5Press until you see On, and then press .

The utility can be turned off from the operator panel or by turning the printer off.

The Coverage Estimator utilizes an algorithm that counts pixels for each toner color: black, cyan, magenta, and yellow. Once the utility is turned on, the printer prints the percent coverage for each color on each page of the job.

The Coverage Estimator is only intended to estimate the coverage on a given page. For all toner colors that are used, the minimum percentage that prints is 2 percent. Reported values may vary from printer to printer. The accuracy of the estimates may be affected by how full the print cartridges are, environmental conditions, the media type, the software application, software settings, the driver, driver settings, and the content of the page. Lexmark makes no claim as to the accuracy of the estimated percents.

Size sensing

The Size Sensing menu item lets you disable or enable auto size sensing on trays. Size Sensing also lets the printer detect the difference between similar paper sizes that it otherwise cannot.
