550 Option Drive Assembly (PL10.1.9)
Step Check
Possible causative parts:
• 550 Option Drive Assembly (PL10.1.9)
• Feeder Motor Harness Assembly (PL10.1.16)
• 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 550 Option Drive Assembly operation
Execute Digital Output diagnostic test 071-014, and check
the 550 Option Drive Assembly rotation.
Does the 550 Option Drive Assembly function normally?
2 Check the 550 Option Drive Assembly installation
Rotate the 550 Option Drive Assembly manually. Is there an
overload?
3 Check the 550 Option Drive Assembly connection
Check the connection between the 550 Option Drive
Assembly and the 550 Option Feeder Board.
Are P/J4221 and P/J422 connected securely?
4 Check the continuity between the 550 Option Drive
Assembly and the 550 Option Feeder Board
Is each cable of P/J4221<=>P/J422 continuous?
5 Check the power to the 550 Option Drive Assembly
(+24 VDC)
Close the interlock switch(es), and check if the voltage
between the 550 Option Feeder Board ground and the
P/J422-6 pin is about +24 VDC.
6 Check the power to the 550 Option Feeder Board (+24 VDC)
Close the interlock switch(es), and check if the voltage
between the 550 Option Feeder Board ground and the
P/J419-6 pin, and the voltage between the 550 Option
Feeder Board ground and the P/J419-7 pin is about +24 VDC.
7 Check the power from the MCU Board (+24 VDC)
Close the interlock switch(es), and check if the voltage
between the MCU Board ground and the P/J271-4 pin, and
the voltage between the MCU Board ground and the P/J27-5
pin is about +24 VDC.
