Troubleshooting: To test the SOS signal, print a test pattern from the Test
Print menu, as shown in Section 3.3. If the test pattern prints with no image
defects, the test is successful.
Test the scanner motor by entering the 1701 code 0610 to invoke the scanner
motor test, as shown in Section 3.1.3. When entered, the motor should run for
20 seconds and then display a Pass or Fail message. The top cover interlock
switch must be depressed to enable the +5 and +24 Vdc LVPSA power.
1. Inspect the following cables and connectors:
• 12-pin plug that connects the scanning assembly to the wire harness
• Wire harness and connectors running between the scanning assembly
and P36 on the DC control board
• 2-pin plug that connects to the scanner interlock switch
