7-bin Tabletop Mailbox Motor Test This test allows you to verify the functionality of the main motor, face-down solenoid, and face-up diverter solenoid. 1 The top cover and paper access door must be closed to perform this test. 2 Set the DIP switches for the motor test (see table 7-28). 3 Pull out the power supply switch to the test position. 4 Press and hold in the interlock switch. A self-test should be performed, then the main motor will start moving continuously until the interlock switch is released. The service LED will flash every 0.5 seconds. If any other pattern results with the service LED, see table 7-29 on page 424 for the possible causes. 5 Push in the power supply switch to the normal position. 7-bin Tabletop Mailbox Standalone Running Test This test allows you to feed paper into the unit to test the paper path without a connection to the printer. You can configure either the Mailbox Mode or the Stacker Mode to ensure the paper path is working properly. 1 The top cover and paper access door must be closed to perform this test. 2 Set the DIP switches for the standalone running test in either Mailbox Mode or the Stacker Mode (see table 7-28 on page 422). 3 Pull out the power supply switch to the test position. 4 Press and hold in the interlock switch. Perform a self-test. Then manually start feeding paper. • In Mailbox Mode, the unit will deliver paper to all bins, starting with the left output bin, then down to the bottom bin. • In Stacker Mode, the unit will stack paper starting at the bottom bin until the top-of-stack is reached on each bin. 5 If problems are found, the possible cause will be indicated by the Service LED (see table 7-29 on page 424). 6 Push in the power supply switch to the normal position.
