6-26
E711
0001
Data is written to the error register of the communication IC (IPC) on the
reader controller PCB four times or more within 1.5 sec.
0002
Data is written to the error register of the communication IC (IPC) on the
DC controller PCB four times or more within 2 sec.
0003
Data is written to the error register of the communication IC (IPC) on the
main controller PCB four times or more within 2 sec.
Main cause
The connector has poor connection. The ADF controller PCB is faulty. The
finisher controller PCB is faulty. The DA unit PCB is faulty. The card
reader PCB is faulty.
Action
a. E711-0001
Connector, ADF controller PCB
Is the interface cable between the ADF controller PCB an the reader con-
troller PCB normal?
NO:
Correct the cable.
YES: Replace the ADF controller PCB.
b. E711-0002
connector, Finisher controller PCB
Is the interface cable between the finisher controller PCB and the DC con-
troller PCB normal?
NO:
Correct the cable.
YES: Replace the finisher controller PCB.
c. E711-0003
Connector, DA unit PCB
Is the interface cable between the DA unit PCB and the main controller
PCB normal?
NO:
Correct the cable.
YES: Replace the NE controller PCB.
