9.7.10 Direction Solenoid Failure
1 Does the Direction Solenoid function correctly?
NOTE: Execute Diagnostic Mode 1, Direction Solenoid, and check the operation.
Y: Check the condition of the Solenoid Lever and the Exit Gate.
N: Go to step 2.
2 Check the voltage applied to the Solenoid. There is +24VDC between P224-11 and P224-8.
Y: Go to step 3.
N: Go to step 6.
3 Check the signal to the Solenoid. The voltage between P/J224-10 and P/J224-8 is at the low
level when the OCT is selected and at the high level (+24VDC) when not selected. The voltage
between P/J224-12 and P/J224-8 is at the high level (+24VDC) when the OCT is selected and at
the low level when not selected.
Y: Replace the Direction Solenoid.
N: Go to step 4.
4 Check the Connector Harness Assembly. There is continuity between J224 and J228.
Y: Go to step 5.
N: Replace the Connector Harness Assembly.
5 Check the resistance of the windings of the Solenoid. The resistance between J228-1 and J228-
2 is about 90
Ω.
The resistance between J228-3 and J228-2 is about 90
Ω.
Y: Go to step 6.
N: Replace the Direction Solenoid.
6 Check the voltage applied to the Solenoid. There is +24VDC between P21-9 and P21-10.
Y: Go to step 7.
N: Go to
RAP 7.4.7 Low Voltage Power Supply (LVPS) Assembly Failure (+24VDC).
7 Check the control signal of the Solenoid. The voltage between P/J21-11 and P/J21-8 at the low
level when the OCT is selected and at the high level (+5VDC) when not selected.
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.
