How do I print a cleaning page on the HP LaserJet Pro 200?

On the home screen, touch the Settings button, then touch the Service Menu, and touch the Clean Page button. When prompted, insert regular letter or A4 paper. Touch OK to start the cleaning process—the product will print one side, prompt you to remove the paper from the output tray, then reinsert it into Tray 1 in the same direction before continuing. Discard the printed page when the process ends. (Page 16)
