7. SERVICE CALL INDICATIONS TABLE

No. Description /Definition
E-00 Clamper Motor Failure
The main PCB cannot detect the master
clamper switch signals (Open/Close)
within 1.2 seconds after the clamper
motor is turned on.
E-01 Cutter Unit Failure
Neither the left nor right cutter switch
turns on within 2 seconds after the
cutter motor is turned on.
E-04 Thermal Head Overheat
Temperature of the thermal head is
greater than 48°C when the Master
Making key is pressed.
E-06 Main Motor Failure
The main PCB cannot detect the feed
start timing sensor signal within 2
seconds after the main motor is turned
on.
E-07 ROM Data Error
The CPU detects errors in the ROM
data when the main switch is turned on.
E-08 Power Supply Unit Overheat
The main PCB receives the overheat
signal from the power supply unit when
the Master Making key is pressed.
E-09 Thermal Head Thermistor Open
The thermistor output voltage
(CN104-13) is over 2.83 volt.
E-10 Thermal Head Drive Failure
The CPU detects abnormal condition in
the thermal head drive circuit.
E-12 Pressure Plate Motor Failure
The pressure plate home position
sensor signal is not detected within 3
seconds after the pressure plate motor
is turned on.
