FIP2.10 SENSOR DUP

Step
Possible causes:
SENSOR DUP (PL21.1.34)
ACTUATOR DUP (PL21.1.37)
HARNESS ASSY DUP SNR (PL21.1.35)
PWBA DUPLEX (PL21.1.32)
HARNESS ASSY DUP (PL21.1.7)
HVPS/MCU (PL12.1.19)
LVPS (PL12.1.5)
HARNESS ASSY LVPS (PL12.1.1)
Checking ACTUATOR DUP for operation
Does ACTUATOR DUP operate smoothly?
1 Does the flag go into the sensor detecting area when
there is no paper in the Option Duplex, and out of the
detecting area when the paper is set?
Checking SENSOR DUP (1)
Remove EP CARTRIDGE.
Close COVER OPEN (PL1.1.2).
Open COVER HSG DUP (PL21.1.18) and keep open.
2
Does the number increase one by one, every time
ACTUATOR DUP operates?
Check using Chapter 2 Diagnostic [Sensor/Switch
Check].
Checking SENSOR DUP (2)
Remove EP CARTRIDGE.
Close COVER OPEN (PL1.1.2).
3 Open COVER HSG DUP (PL21.1.18) and keep open.
Is the voltage across P/J53-3(+) and P/J53-2(-), 0 VDC
when ACTUATOR DUP is pushed, and 3.3 VDC when
released?
Checking SENSOR DUP (3)
4 Replace SENSOR DUP. (RRP21.7)
Does the problem still occur after replacement.
Checking HARNESS ASSY DUP SNR for continuity
Remove SENSOR DUP.
5 Disconnect P/J53 from PWBA DUPLEX.
Does each cable between J53 and J530 have continu-
ity?
Checking HARNESS ASSY DUP for continuity
6 Remove HARNESS ASSY DUP.
Is there continuity between J50 and J2750?
Checking HARNESS ASSY LVPS for continuity
7 Remove HARNESS ASSY LVPS.
Is there continuity between J27 and J2750?
Checking HVPS/MCU for continuity
8 Disconnect P/J11 from HVPS/MCU.
Is there continuity between P11-16 and P27-4?
