4.3 SERVICE CALL CODES

No.
E-00 Clamper Motor Failure
The MPU cannot detect the master
clamper position sensor signal (open or
closed) within 1.2 seconds after the
clamper motor turns on.
E-01 Cutter Failure
The cutter HP sensor does not turn on
within 3 seconds after the cutter motor
turns on.
If the master is not cut at the end of the
master making. The drum master
detection sensor is used to check if the
black cover at the trailing part of the
drum cloth screen is covered by the
master just before the drum returns the
home position. In this case, the SC is
cleared once the power is off.
E-02 Paper Table Drive Failure
The paper height sensor or the table lower
limit sensor does not turn on within 7
seconds after the table drive motor turns
on.
E-04 Thermal Head Overheat
Temperature of the thermal head is
greater than 54 C when the Start key is
pressed.
E-06 Main Motor Lock
The CPU cannot detect the feed start
timing sensor signal within 2 seconds after
the main motor turns on, or the sensor
remains on for more than 0.5 seconds.
E-09 Thermal Head Thermistor Open
The thermistor output voltage (CN109-A1)
is over 4.9 volts.
E-10 Thermal Head Drive Failure
The CPU detects an 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 4 seconds
after the pressure plate motor turns on.
