Paper-path test This diagnostic test generates one or more test pages that you can use to isolate the cause of jams. To isolate a problem, you can specify which input tray to use, specify whether to use the duplex path, and specify the number of copies to print. Multiple copies can be printed to help isolate intermittent problems. The following options become available after you start the diagnostic feature: ● Print Test Page. Run the paper-path test from the default settings: Tray 2, no duplex, and one copy. To specify other settings, scroll down the menu and select a setting, and then scroll back up and select Print Test Page to start the test. ● Source. Select Tray 1, Tray 2, or the optional trays.
