corrupted when the network enable
switch and Cumin-M were enabled
at the same time.

651
Illegal Remote Service Dial-up
An expected error occurred when
Cumin-M dialed up the NRS
Center.
670 D Engine startup error
The machine engine, controlled by
the BICU (Base Image Control
Unit), was operating incorrectly
when the machine was switched on
or returned to normal operation
from the energy save mode.
672 B Controller startup error
• After power on, the line between
the controller and the operation
panel did not open for normal
operation.
• After normal startup,
communication with the controller
stopped.
Solution
In the User Tools, check the dial-up user and dial-
up password settings
Check the setting of SP5816 160 to determine
whether the setting for the AT command is correct.
If this SP setting is correct, then the problem is a
bug in the software.
The problem is on the external power supply line, so
there is no corrective action on the machine.
Use SP5985 1 and set the NIC to "0" (Disable) to
disable the network board.
Replace the modem board.
Symptom

Check the following for a machine that is
using Cumin (NRS modem):

connection
• A network was detected at startup
• At startup the machine detected that the

Possible Cause
• Software bug

count is logged

and controller
• BICU defective
• Controller board defective
• PSU defective
