H 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 RS232 C
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.
