7-bin Tabletop Mailbox Sensor Test This test allows you to check if all unit sensors are working properly. By activating any unit sensor flag, the service LED should turn on. 1 Make sure that all bins are empty to perform the sensor test. 2 Set the DIP switches for the sensor test (see table 7-19 on page 448). 3 Do NOT press the interlock switch in at this time. 4 Pull out the power supply switch to the test position. 5 Make sure that the service LED is off. 6 Manually activate any sensor flag. The service LED should turn on if the sensor is functional.
Note To test the top cover or paper access door switches, you need to open one of them while you perform the standalone running test (page 449). As soon as you open the top cover or paper access door, the test should stop and the LED should indicate that one door is open with a blinking pattern of one long and one short. Close the top cover or paper access door. A self-test will be performed. The test continues, and the service LED continues to blink every 0.5 seconds. CAUTION Be sure to turn the power supply off and set all the DIP switches to the off position (normal settings) when you finish the diagnostics or the printer will not work properly. Replace the back cover.
