7.4.5 Low Voltage Power Supply (LVPS) Assembly Failure (+5VDC)
NOTE: Ensure the Front Interlock and the Laser Diode Interlock are actuated.
1 Check for +5VDC between P/J11-13 (5V INTLK) and P/J12-5.
Y: Go to step 6.
N: Go to step 2.
2 Check for +5VDC between P/J131-3 and P/J12-5.
Y: Perform a continuity check between P/J131-3 and P/J11-13 before replacing the Print
Engine Controller.
N: Go to step 3.
3 Check for +5VDC between P/J136-4 and P/J131-3.
Y: Replace the harness between P/J136-4 and P/J12-5.
N: Go to step 4.
4 Check for +5VDC between P/J 136-2 and P/J12-5.
Y: Replace the jumper/harness between P/J136-2 and P/J136-4.
N: Go to step 5.
5 Check for +5VDC between P/J131-1 and P/J12-5.
Y: Replace the wire harness between P/J131 and P/J136.
N: Replace the LVPS Assembly.
6 Check for +5VDC between P/J25-2 and P/J25-5 (disconnect P/J25).
Y: Replace the Print Engine Controller.
N: Go to step 7.
NOTE: Conduct this analysis before the LVPS Assembly would stop voltage output due to the absence
of sufficient load (within 30 seconds after switching on the printer power).
7 Check for +5VDC between P/J12-2 and P/J12-5 (disconnect P/J25 for this check).
Y: Replace the LVPS.
N: Replace the LVPS.
NOTE: If the +5VDC was present with P/J13 or P/J25 disconnected and disappears when the P/J is
connected, check for a possible short to earth ground on that part5VDC output of the Print
Engine Controller. Otherwise, replace the LVPS.
