• 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 hexadecimal dump function, the printer prints all commands
and other data in hexadecimal format along with a guide section to help
you find specific commands.
To use the hexadecimal dump feature, follow these steps:
1) After you make sure that the printer is off, open the front cover of the
printer.
2) Hold down the Feed button while you turn on the printer.
3) Close the front cover.
4) Run any software program that sends data to the printer. The printer
prints “Hexadecimal Dump” and then 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 correspond to the
codes.
• A period(.) is printed for each code that has no ASCII equivalent.
5) When the printing finishes, turn off the printer.
