6.1 Bad Power or Control Panel FIPs
Symptom 2: The following symptoms indicate a malfunctioning ac power line
or low-voltage power supply assembly (LVPSA):
• The printer blows the fuse or circuit breaker that supplies the AC line
power.
• No normal power up sounds, rounding, or roller motion
• The control panel display and indicators are blank and never turn on.
• The printer runs for a short time then shuts down or is intermittent.
Action: Do the following to fix a power problem:
1. Try another ac line plug and swap the power cord.
2. If the ac wall power is bad, call the site electrician to restore power.
3. Remove the right side panel and metal card cage.
Refer to Figure 6–1 for connector and pin numbers mentioned in the
following steps.
4. Inspect the 6-wire cable that runs from the DC control board to the J103
connector on the LVPSA. Make sure it is properly plugged in and in good
condition.
5. Remove the video controller board and all optional equipment.
6. Press the test print switch to see if the printer can print or use a VOM to
measure the power supplies from the LVPSA on J103.
7. Skip the following and go to step 8 if the printer fails to print or if the
VOM fails to measure +5 and +24 Vdc.
• Replace the video controller board and removed options one at a time
to find the bad FRU.
• If the power failure is intermittent, inspect the two SIMM memories.
The use of nonspecified third-party SIMMs can cause power problems,
but only if the printer is fully equipped with all possible optional
equipment.
8. Swap the following FRUs:
a. LVPSA
b. Fusing unit
c. DC controller board
