c. Carefully touch the + of the VOM to pin-4 of J211 on the DC control
board. Be careful to not short adjacent pins.
d. As you manually actuate the top door switch, VOM should switch
between +24 volts and zero volts.
• If this test works go to the step 7.
• If pin-4 fails to go to +24 volts, swap the following FRU:
– DC control board
– Feed unit or feed unit controller
– Feed unit and option interconnect
7. Swap the following FRUs:
• DC control board
• Main motor
6.15 58 ERROR
Explanation: This is an exhaust fan error. The single speed exhaust runs
when the DC control board asserts the signal. If the exhaust fan stalls,
the exhaust fan asserts the signal that is detected by the DC control
board.
Signal diagram reference: See section Figure 6–4 for wiring diagrams.
Action: Do the following:
1. Remove the right-side cover and video controller board.
2. Inspect the exhaust fan blades for foreign objects that might stall the fan
and produce this error.
3. Inspect the connector and cabling that runs between J209 on the DC
control board and the exhaust fan. Make sure the connector is plugged in
and the cable is in good shape.
4. Swap the following FRUs:
• DC control board
• Exhaust fan
