Error Code Indication
Upon an error with the printer, its Ready/Manual/Error LED starts blinking. Then, the status of the LEDs is
changed every time a switch on the printer is pressed. Each lighting pattern of the LEDs indicates an error
code. The code is a three-digit decimal number, expressed using twelve bits (three LEDs x 4). With
the fifth press of the switch, the LED that started blinking, i.e. turned to a blinking state, with the error
returns to the blinking state.
