OUTPUT BIN TESTS Feed Test Feed to all Bins Diverter Test Sensor Test Feed Test Note: If the "Configure Bins" printer setting is link rather than mailbox, the printer selects its own internal bin linking regardless of which output bin is selected for the feed test.

Select Feed Test from the OUTPUT BIN TESTS menu. 2. Select the output bin you want the paper to exit into. All output bins installed on the printer are shown on 3. 4. the feed test menu. For example, Standard Bin. Select either Single (one sheet of media feeds to the selected output bin) or Continuous (media continues feeding to the selected output bin) until Return or Stop is pressed. Press Return or Stop to exit the test. Feed to All Bins One page is fed to every bin, including the finisher, if available. The test runs continuously until Return or Stop is pressed.
