Getting printer information If you need to call the Customer Care Center, you should print a diagnostic page and a configuration page to obtain printer information. Such information is useful to our Customer Care Center in helping you troubleshoot printer problems. You can also get printer information from the Toolbox by clicking Printer Hardware under the Information tab. Information on the printer, battery, connectivity, and media types used is available. Printing diagnostic and configuration pages The diagnostic page contains detailed printer information, including firmware version number, serial number, service ID, and print cartridge information. The configuration page contains information such as default page settings, printer media settings and Bluetooth connectivity status. The printer must not be processing any print jobs while you print the diagnostic or configuration pages. To print a diagnostic page: Hold down the POWER BUTTON and press the RESUME BUTTON 4 times.
