detected normally.
Error : Disconnection/short circuit of the tape
dispenser thermistor
E024
The thermistor of the tape dispenser PCB detects
abnormal temperature.
Error : EEPROM (for standard)
Write/readout to the EEPROM for standard is
E030
defective.
Error : Panel communication
Communication between the main PCB and
E032
the panel PCB is defective.
Error : SDRAM
E033
Write/readout to the image memory of the
main PCB is defective.
Error : Storage/clear of memory function
E034
The memory function storage contents are not
stored/cleared in the memory PCB normally.
Error : USB host
