042-326 IOT Motor Failure
Step Check
Possible causative parts:
• Paper Transport Motor [Drive Assembly] (PL3.1.1)
• Drive Harness Assembly (PL18.2.2)
• Top Harness Assembly (PL18.2.5)
• LVPS (PL18.1.34)
• MCU Board (PL18.1.13)
1 Check the Paper Transport Motor operation
Execute Digital Output diagnostic test 071-004, and check
the Paper Transport Motor rotation.
Does the Paper Transport Motor function normally?
2 Check the Paper Transport Motor connection
Check the connection between the Paper Transport Motor
and the LVPS, and the connection between the Paper
Transport Motor and the MCU Board.
Are P/J312, P/J509, P/J172, and P/J17 connected securely?
3 Check the continuity between the Paper Transport Motor
and the MCU Board
Is each cable of P/J172<=>P/J17 continuous?
4 Check the continuity between the Paper Transport Motor
and the LVPS
Is each cable of P/J312<=>P/J509 continuous?
5 Check the power to the Paper Transport Motor (+24 VDC)
Close the interlock switch(es), and check if the voltage
between the LVPS ground and the P/J509-3 pin is about
+24 VDC.
