Y: Go to step 7.
N: Go to RAP 7.4.5 Low Voltage Power Supply (LVPS) Assembly Failure (+5VDC).
7 Check the signal of the Stack Full Sensor (STK FULL SNR (OCT)). There is +5VDC between
P21-2 and P21-8, when the OCT is full.
Y: Go to step 8.
N: Replace the Print Engine Controller.
8 Check the signal of the Stack Full Sensor (STK FULL SNR (OCT)). The voltage between P/J21-2
