9.7.7 OCT Exit Sensor Failure
1 Check the voltage applied to the OCT Exit Sensor Assembly. There is +1.2VDC between P224-7
and P224-8.
Y: Go to step 2.
N: Go to step 5.
2 Check the signal of the OCT Exit Sensor Assembly (OCT EXIT SNR). There is +5VDC between
P224-9 and P224-8.
Y: Go to step 3.
N: Go to step 6.
3 Check the signal of the OCT Exit Sensor Assembly (OCT EXIT SNR). The voltage between P/
J224-9 and P/J224-8 is at the high level when paper is not present and at the low level when
paper is present.
Y: Go to step 7.
N: Go to step 4.
4 Check the Connector Harness Assembly. There is continuity between J227 and J224.
Y: Replace the OCT EXIT Sensor Assembly.
N: Replace the Connector Harness Assembly.
5 Check the voltage applied to the OCT Exit Sensor Assembly from the Print Engine Controller.
There is +5VDC between P21-7 and P21-8.
Y: Go to step 8.
N: Go to
RAP 7.4.5 Low Voltage Power Supply (LVPS) Assembly Failure (+5VDC).
6 Check the signal of the OCT Exit Sensor Assembly (OCT EXIT SNR). There is +5VDC between
P21-12 and P21-8 (paper not present).
Y: Go to step 7.
N: Replace the Print Engine Controller.
7 Check the signal of the Sensor Assembly (OCT EXIT SNR). The voltage between P/J21-12 and
P/J21-8 is at the high level when paper is not present and at the low level when paper is present.
Y: Replace the Print Engine Controller.
N: Go to step 8.
8 Check the OCT Harness Assembly. There is continuity between J209 and J202 and between
P202 and J21.
Y: Replace the OCT PWB.
N: Replace the OCT Harness Assembly.
