This printer has a useful Hex Dump Mode for checking the print data sent
from your computer. The printer lists the print data in hexadecimal form.

To enter the hex dump mode, follow these steps:

1. Check the power state.

2. Operate the buttons according to the power state.

  • If the printer has been turned off, turn on the printer.

The printer starts the self-test and the display shows the following
message.

  • If the printer has been turned on, reset the printer with the

 button.

 The display will show “RESET PRINTER”.

3) Press the 

 button with the “RESET PRINTER” selected.

3. Hold down the

 button.

The printer checks the 

 /

 button at the end of self-test

dump mode and goes on-line. The display will show the message
“HEX DUMP MODE” and the printer will return to the on-line state.

✒  Note
If the printer returns to the on-line state without displaying the message
“HEX DUMP MODE”, you did not hold down the

button immediately after pressing the 

 button. Try the above steps

once again.

When the printer receives data, it starts printing hexadecimal values of
