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.

Troubleshooting 3-7

To use the hex dump feature, follow these steps:

1. After you mak e sure the printer is o f f, set DIP swit ch 1- 2 to ON.

2. Turn on the printer while you hold down the PAPER FEED button; then release and press the PAPER FEED button quickly.

Note:

Perform releasing and pressing the PAPER FEED button before the printer finishes initializing; otherwise the printer begins the self test.

3. When the printer enters the hex dump mode, it prints “Hexadecimal Dump.”

4. Run any software program that sends data to the printer. The printer prints 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.

❏ Control codes are printed in bold for emphasis. ❏ During the hex dump all commands except DLE EOT and

DLE ENQ are disabled.

5. When the printing finishes, turn off the printer or reset it to turn off the hex dump mode.

6. If you changed DIP switch 1-2, set it back to OFF.
