4-642 Belt Edge
IBT belt edge not in position.
Procedure
BSD: CH9.19 CH9.31A
Check if actuator for IBT Edge Sensor touches belt edge. IBT Edge Sensor touches belt
edge.
YN
Check actuator installation.
Turn the power ON. Between I/F PWB j533-A11(+) and GND(-). Between +3 VDC and 1
VDC is measured.
YN
Between I/F PWB j533-A9(+) j533-A10(-). +5 VDC is measured.
YN
Close FRONT door. If voltage between j533-A9(+) j533-A10(-) is less than +5VDC,
replace MCU PWB (PL 13.1).
Between I/F PWB j533-A11(+) and GND(-). +5 VDC is measured.
YN
Between I/F PWB j533-A11(+) and GND(-). 0 VDC is measured.
YN
Check wire breakage and bad connection between I/F PWB j533and IBT Edge
Sensor j119.
If the check is good, replace IBT Edge Sensor (PL 5.4).
If the problem continues, replace MCU PWB (PL 13.1).
Check wire breakage and bad connection between I/F PWB j533-A11 and IBT Edge
Sensor j119-2.
Replace IBT Edge Sensor (PL 5.4).
Between I/F PWB j530-A9(+) and GND(-). +24 VDC is measured.
YN
Following Wire Network, check +24VDC circuit up to I/F PWB j530-A9
Remove IBT Assembly (REP 9.15). Enter dC330 [004-001] and press Start. IBT Steering
Motor energizes.
YN
Check wire breakage and bad connection between I/F PWB j550 and IBT Steering Motor
j207. There are broken wires or bad connections.
YN
Replace MCU PWB (PL 13.1).
If the problem continues, replace I/F PWB (PL 9.1).
If the problem continues, replace IBT Steering Motor (PL 1.3).
Repair broken wire and bad connection.
Check IBT Belt installation (REP 9.22). If the check is good, replace MCU PWB (PL 13.1).
4-650 IOT Cycle Down Time Out
Incorrect print processing continued for 2 minutes.
Procedure
Check the wire between the ESS PWB and the MCU PWB for a poor contact. The problem
continues.
YN
Return to Service Call Procedures.
Replace the ESS PWB (PL 13.1)
