2-2-3 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 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 rear cover of the printer.
2) Hold down the FEED button while you turn on the printer.
3) Close the rear cover.
4) Run any software program that sends data to the printer. The printer prints "Hexadecimal dump" and then
all the codes are received 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.

2-2-4 The self Test Mode
The self test let you know if your printer is operating properly. It checks the printing quality, ROM version, DIP
Switch settings, memory switch settings and statistic data.
The test is independent of any other equipment or software, so it is a good idea to run it when you first set up
the printer or if you have any trouble. If the self test works correctly, the problem is in the other equipment or
the software, not the printer.

Running the self test
1) Make sure the printer is turned off and the printer cover is closed properly.
2) While holding down the FEED button, turn on the printer and continue to hold until the paper begins to
feed. The self test prints the printer DIP Switch settings and memory switch settings. And cuts the paper
and pauses.
3) Press the FEED button to continue printing the rolling ASCII pattern.
4) The self test mode terminates after printing the rolling ASCII pattern automatically.
