Check that the clock signal (6
MHz) is input to the USB
controller (IC706).
Check if the driver has been
installed in the PC.
Check the status of the USB
controller (IC706) with the auto
device diagnosis or the status
LEDs.
If it has not, install the driver.
If the USB controller (IC706) is judged as NG,
it has not been correctly started up. See “[8]
Auto device diagnosis/Status LEDs” in this
section.
Check that V+BUS5D is input to
Pin 46 of the USB controller
(IC706).
If it is not, the USB controller (IC706) has not
started. If the USB controller is not properly
soldered, resolder it.
As this clock is for communication, connection
disruption cannot be detected by auto device
diagnosis. Check the mounting status of the
crystal oscillator (X701) and its peripheral
devices. If they are properly mounted, they are
defective; replace them.
Check that the USB cables and
USB auxiliary power cable are
securely connected.
Check the power (V+BUS5D) to
the NJACK Assy.
If V+BUS5D is not supplied, check the voltage
of V+DCIN5D and V+USB5D.
If both V+DCIN5D and V+USB5D are supplied,
check the mounting status and output voltages
of IC2204, Q2201, and Q2202. If there is no
voltage output even if there is an input voltage,
the corresponding part is defective; replace it.
Operation may be unstable if either of the
cables is not properly connected.

Has the updating of the firmware
for the control unit failed?
If updating fails, operation stops, none of the
