Power Save And Led Rap - Xerox DocuColor 12/DCCS50 Service Manual

Power Save and LED RAP

This RAP is used to repair failures in the Power Save and LED Circuit.
Initial Actions
• Use BSD 2.3 in the following procedure:
• Check if the Power Save Mode activates continuously or will not activate.
Procedure
PO/PO the machine. The machine remains in the Power Save (Sleep) Mode.
Y N
The machine wakes up. Check for +5 VDC at P/J11A-A7 on the AC Driver PWB.
+5 VDC is measured at P/J11A-A7 on the AC Driver PWB.
Y N
Perform the following:
• Go to BSD 2.3, Flag 1 and check for a short circuit.
• Go to the +5 VDC Power (IOT LVPS)
Enter dC330 001-200 Power Save Button, and exercise the Power Save Mode using the
following procedure:
1. Press Start.
2. Press and hold the [Power Save Button]. For normal operation the status indicator
should indicate Logic (H) and the counter should increment.
3. Release the Power Save Button and the status should change to Logic (L), and the
counter should increment again.
The Power Save Mode behaved normally when it was exercised in the preceding
steps 1 through 3.
Y N
Check the voltage at P/J11A-A12 on the AC Driver PWB
sured at P/J11A-A12 on the AC Driver PWB
Y N
Perform the following:
• Check the wire between P/J11A-A12 on the AC Driver PWB, and P/J492-
2 on the Control Panel for a short circuit.
• Replace the Control Panel
• Replace the AC Driver PWB
Perform the following:
• Check the wire between P/J11A-A12 on the AC Driver PWB, and P/J492-2 on
the Control Panel for an open circuit.
• Replace the AC Driver PWB
• Replace the Control Panel
Perform the following:
• Go to Flag 2 on BSD 2.3, and check for an open circuit.
• Replace the Control Panel (PL 9.5).
• Replace the IOT CPU PWB (PL
• Replace the IOT Drive PWB (PL
