Caution:
Whenever you turn off the printer, wait at least five seconds
before turning it back on; otherwise you may damage the printer.
2. To enter hex dump mode, hold down both the LF/FF and
Load/Eject buttons while you press the Operate button to turn
on the printer.
3. Open a software program and send a print job to the printer.
Your printer prints all the codes it receives in hexadecimal
format.
If characters are printable, they appear in the right column as
ASCII characters. Nonprintable codes, such as control codes,
are represented by dots. By comparing the characters printed
in the right column with the printout of the hexadecimal
codes, you can check the codes the printer is receiving.
4. To turn off hex dump mode, press the Pause button to stop
printing and the Load/Eject button to eject the printed page(s).
Then turn off the printer.
