2 Problems at Time of Installation
The G3 FAX board is not recognized.
Cause:
The main controller will automatically identify the presence of a G3 fax
control PCB by communication with it at time of power-on. The cable
used for the communication may not be connected.
Remedy:
Check to see if the cable between the main controller PCB and the G3
fax control PCB is correctly connected. (J1005 on the main controller
PCB, J31 on the G3 fax control PCB)
E674-0001 Error
Cause:
E674-0001 is indicated when the MPU of the G3 FAX control PCB
does not respond although the main controller PCB and the G3 fax con
troller PCB are electrically connected. It also occurs when the G3 FAX
control PCB is not supplied with power and, as a result, the MPU of the
G3 fax board is not operating.
Remedy:
Check to see if the cable between the main controller PCB and the G3
fax control PCB is correctly connected. (J1005 on the main controller
PCB, J31 on the G3 fax control PCB)
Remedy:
Check to see if the G3 FAX Board DIMM is correctly installed. Or, the
program in the DIMM may be out of order. Replace the DIMM with a
normal one.
Remedy:
Check to find out if the power line to the G3 FAX Board is correctly
connected. (J104 on the G3 fax control PCB and J124 on the
low-voltage power supply PCB)
