leading to loss of SRAM
contents.
An error has occurred in
communication between the fax
E674- control PCB (2-line) and main
0001 controller PCB.
An attempt to set mode for the
fax device has failed.
There is an error in the
initialization of the IPC.
E710-
The machine fails to become
0001
ready 3 sec or less after the
IPC chip startup.
There is an error in the
initialization of the IPC.
E710- When the main power is turned
0002 on, the communication IC (IPC)
on the DC controller PCB
cannot be initialized.
Code
There is an error in the IPC
communication.
E711-
The occurrence of an error has been
0001
recorded in the error register of the IPC
chip 4 times or more within 1.5 sec.
There is an error in the IPC
communication.
E711-
The occurrence of an error has been
0002
recorded in the error register of the IPC
chip 4 times or more within 2 sec.
There is an error in the communication
with the finisher.
E713-
The communication with the finisher
0000
does not resume within 5 sec after it has
been disrupted.
There is an error in the communication
with the pedestal.
E716-
After the presence of a pedestal has
0000
been detected, the communication fails
to be normal for 5 sec
There is an error in the communication
E717-
with the NE controller.
0001
The NE controller is not connected at
board on which the SRAM is mounted. (Keep in mind
that doing so will lead to loss of all user data.)
1. Check the connection of the cable between the fax
control PCB (2-line) and the main controller PCB. 2.
Replace the ROM DIMM of the fax control PCB (2-
line). 3. Replace the fax control PCB (2- line). 4.
Replace the main controller PCB.
Check the cable.
Check the cable.

Remedy
Check the cable.
Check the cable.
Check the cable. Replace the DC controller
PCB. Replace the finisher controller PCB.
Check the cable. Replace the DC controller
PCB. Replace the pedestal drive PCB.
Check the cable; thereafter, reset the
condition in service mode:
