To isolate a jam, you can specify which input tray to use, which output bin to use, whether to use the duplex path, and the number of pages to print. Printing multiple pages helps to isolate intermittent jam problems. The following options are available for this test. ■ Print test page. This option uses factory default settings to run the paper path test. The page starts from tray 2, does not use the duplex path, and prints a single page. The user can specify the number of pages to be printed. ■ Source. Use this option to select tray 1, tray 2, or tray X (if optional tray feeders are installed) as the page source. ■ Destination. Use this option to send the test page to the optional stacker or stapler/stacker if this accessory is installed. ■ Duplex. Use this option to send the test page through the duplex path. ■ Page count. Use this option to sets the number of test page copies to be printed. The choices are 1, 10, 50, 100, and 500.
