Case 2
The problem below occurred:
X=8 (PCB-ASSY-IPB5-100 P38VAF)
Note:
The power supply system related to this error number is generated from the PSU 38V, and the
power is supplied by passing through the interlock relay. So check the Items to be Checked on
the table below, and perform the actions starting from the top until the problem is solved.
Power supply unit (38V) harness
(1) Reconnect the CABLE(PSU-ACT-IF)-ASSY(MW) to
the ACT3 and the power supply.
(2) Reconnect the CABLE(PSU-ACT)-ASSY(MW) to the
ACT3 and the power supply.
Cable between the ACT3 and
IPB5
Reconnect the CABLE(ACT-IPB-IF)-ASSY(MW) to the
ACT3 and the IPB5.
Replace the PCB-ASSY-ACT3.
Replace the PCB-ASSY-IPB5-100.
Replace the power supply unit (38V).
Case 3
The problem below occurred:
X=6 (PCB-ASSY-ACT3 P38VAR)
Note:
The power supply system related to this error number is generated from the PSU 38V, and the
power is supplied to the PCB-ASSY-IPB5-100 by passing through the interlock relay. So check
the Items to be Checked on the table below, and perform the actions starting from the top until
the problem is solved.
Check that the printer detects
the interlock switch position
(ON/OFF)
Open and close the front cover, and check that the printer
detects the interlock switch position.
If the Printer does not react to the interlock switch position,
check that the PCB-ASSY-ACT3’s connector CN2 is
connected.
If the error persists, check that the interlock switch’s
connector is connected.
If the error still persists, replace the interlock switch.
Cable between the ACT3 and
IPB5
Reconnect the CABLE(ACT-IPB-IF)-ASSY(MW) to the
ACT3 and the IPB5.
Replace the PCB-ASSY-ACT3.
Replace the PCB-ASSY-IPB5-100.
Replace the power supply unit (38V).
