P O I N T
The EEPROM (Address: 3CH) stores the error code of the
latest fatal error.
The latest fatal error can be identified using the adjustment
program.
In case any fatal error (such as memory check) other than those
in the Printer Mechanism occurs, all the LEDs (x5) flash
without any indication on the LCD. Pressing the Change View
button during flashing will display the error code, so that you
can identify the error from the error code.
