E197 0000 Printer engine communication error
Erroneous communication between the DC controller PCB and
image processor PCB was detected. - Check the connectors of the DC controller PCB and image
processor PCB.
- Replace the DC controller PCB for normal connection.
- Replace the image processor PCB.
E261 0000 Zero-cross signal error
If failed to detect zero-cross signal cycle of the power supply
when initializing.
When the input of the zero-signal failed continuously for three
seconds while controlling the temperature adjustment. - Replace the power supply PCB.
- Replace the DC controller PCB.
E716 0000 Erroneous communication with optional cassette
Disconnection of the optional cassette was detected after
power-on, detection of normal connection to the optional
cassette, and start of communication. - Check the connectors of the optional cassette PCB and DC
controller PCB.
- Replace the optional cassette PCB for normal connection.
- Replace the DC controller PCB.
E719 0000 Erroneous communication with card reader (serial communication)
- Disconnection from the card reader has been detected since
communication started after confirmation of normal connection
to the card reader (after power-on).
- A serial communication error has occurred. (The serial
communication error cannot be recovered.) - Check the connectors of the card reader and image processor PCB.
- Replace the card reader for normal connection.
- Replace the image processor PCB.
0002 Erroneous communication with coin vendor (serial communication)
- Disconnection from the coin vendor has been detected since
communication started after confirmation of normal connection
to the coin vendor (after power-on).
- A serial communication error has occurred. (The serial
communication error cannot be recovered.) - Check the connection between the image processor PCB and serial
PCB.
- Check the connectors of the serial PCB and coin vendor for normal
connection.
- Replace the serial PCB.
- Check the coin vendor.
- Replace the image processor PCB.
E730 0000 Inside error of the image processor PCB (PDL system error)
The inside of the image processor PCB is faulty. - Putting the switch on/off of the power supply.
- Replace the image processor PCB.
E733 0000 Erroneous communication between controller and printer
Cannot communicate with the printer at startup. - Check the connectors of the DC controller PCB and image
processor PCB for normal connection.
- Check the power supply of the printer (Check whether initialization
is performed at startup).
- Replace the DC controller PCB or image processor PCB.
E736 0000 CCU communication error
The installed modem PCB is incompatible. - Check the connectors of the image processor PCB and modem.
- Replace the modem PCB.
- Replace the image processor PCB.
