Maintenance & Troubleshooting
Rev. A
Errors that are impossible to recover:
4.2.4
Printer prints “?“ or Incorrect Data With Serial Interface
If one of the following errors occurs during serial interface communication, the printer prints “?”
or ignores the data, depending on the setting of DIP switch 1-1.
Parity error
Framing error
Overrun error
Note:
For other errors, we recommend confirming the transmission setting of DIP switch 1-3: Handshaking.

Hexadecimal Dump
This feature allows experienced users to see exactly what data is coming to the printer. This can
be useful in finding software problems. When you turn on the hex dump function, the printer
prints all commands and other data in hexadecimal format, along with a guide section to help
you find specific commands.
