(2) Service Call Error
When the service call error occurs, all LED of Power, Paper, and Alarm LED is high-speed
blinked at the same time at 120mS intervals. Under such a condition, it comes into "Error code
display mode" when ONLINE switch and the CANCEL switch are pressed at the same time
for more than five seconds. In this mode, the error code (decimal number of 3-digit) is
expressed by 12 bits (LED3 piece _ four times).
"Error code display mode" is ended if ONLINE switch is pressed for five times, and it returns
to the state of the LED high speed blinking. Moreover, even if the switch is not pressed for
more than 20 seconds, "Error code display mode" would be ended. ...
All LED is turned off immediately after pressing ONLINE switch (200mS), and under the
continuous condition same patterns may also recognize the switch-pressing.
