Chapter 2. Hexadecimal Dumping

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 hexadecimal dump function, the
printer prints all commands and data in hexadecimal format along with a guide section to help
you find specific commands.
To use the hexadecimal dump function, follow these steps:
1. After you make sure that the printer is off, open the cover.
2. Turn on the printer, while holding down the FEED button.
3. Close the cover, then the printer enters the hexadecimal dump mode.
4. Run any software program that sends data to the printer. The printer will print all the codes
it receives in a two-column format. The first column contains the hexadecimal codes and
the second column gives the ASCII characters that corresponds to the codes.
