Using the Hex Dump Mode

The printer can print data in hex dump mode, which allows
experienced users to find the cause of communication problems
between the printer and a software program. In hex dump
mode, the printer prints all data received as characters in
hexadecimal values.
To use hex dump mode, follow these steps:
1. Make sure that paper is loaded in the printer.
2. Hold down both the LF/FF Load and Tear Off buttons
while you turn on the printer.
3. Next, run a software program and send a print job to the
printer. Your printer prints all the codes it receives from
the software in hexadecimal format.
