Path Sensor [550 Option Main Feed Assembly] (PL10.2.1)
Step Check Yes No
Possible causative parts:
• Path Sensor [550 Option Main Feed Assembly] (PL10.2.1)
• C2 Size Harness Assembly (PL10.1.14)
• Drawer 1 Feeder Harness Assembly (PL10.1.13)
• Main Harness Assembly (PL18.2.3)
• 550 Option Feeder Board (PL10.1.10)
• MCU Board (PL18.1.13)
1 Check the Path Sensor operation
Execute Digital Input diagnostic test 071-117, and check the
Path Sensor operation.
Does the Path Sensor function normally?
Replace the MCU
Board.
Go to step 2.
2 Check the Path Sensor connection
Check the connection between the Path Sensor and the 550
Option Feeder Board.
AreP/J4214 and P/J421 connected securely?
Go to step 3. Connect P/J4214
and P/J421
securely.
3 Check the continuity between the Path Sensor and the 550
Option Feeder Board
Is each cable of P/J4214<=>P/J421 continuous?
Go to step 4. Replace the C2
Size Harness
Assembly.
4 Check the power to the Path Sensor (+3.3 VDC)
Check if the voltage between the 550 Option Feeder Board
ground and the P/J23-6 pin is about +3.3 VDC.
Replace the Path
Sensor [550
Option Main
Feed Assembly].
Go to step 5.
5 Check the power to the 550 Option Feeder Board (+3.3 VDC)
Check if the voltage between the 550 Option Feeder Board
ground and the P/J419-4 pin is about +3.3 VDC.
Replace the 550
Option Feeder
Board.
Go to step 6.
6 Check the power from the MCU Board (+3.3 VDC)
Check if the voltage between the MCU Board ground and the
P/J27-7 pin is about +3.3 VDC.
Go to step 7. Refer to
“+3.3 VDC Power
FIP” on
page 2-224.
7 Check the PWBA Assembly FEED connection
Check the connection between the PWBA Assembly FEED
and the MCU Board.
Are P/J419, DP/J271, and P/J27 connected securely?
Replace the
Drawer 1 Feeder
Harness
Assembly
and the
Main Harness
Assembly.
Connect P/J419,
DP/J271, and
P/J27 securely.
