4.3 Interface Troubleshooting

Any interfacing problems can generally be fixed by simply double checking that the

interface connectors are in the correct sockets and securely fastened.

However, for serial interfaces, we recommend the use of Citizen’s standard RS232C

serial cable for correct operation of your printer. In case of interface errors, initially

you should replace the interface cable with a known good cable before contacting our

service personnel.

Details of Citizen’s recommended serial cables are shown below:
