3. Scroll to the print quality test, and press Select.
Three pages print to help you evaluate print quality. The first
page is the print quality test page, the second page is gray, and
the third page is black. Once the paper exits into the output bin,
the MFP returns to the print quality test menu item. Exit
diagnostics to return to the Ready state.
4. Use the test pages to isolate problems such as print too light,
toner streaks, and so on. See the Troubleshooting tables in the
