Using the Hex Dump Mode

If you are an experienced user or a programmer, print a
hexadecimal dump to isolate communication problems
between the printer and your software program. In hex dump
mode, the printer prints all data it receives from the computer
as hexadecimal values.
To print a hex dump, follow the steps below.
1. Make sure that A4 (210 297 mm, 8.3 11.7 inches) or
wider paper (such as letter size paper) is loaded in the
printer.
2. To enter hex dump mode, turn on the printer while holding
down both the LF/FF and Load/Eject buttons.
