from your computer. The printer lists the print data in hexadecimal form.
To enter the hex dump mode, follow these steps:

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 Reset
button.

2) Hold down the Shift button and press the Reset button.
The display will show “RESET PRINTER”.
3) Press the Set button with the “RESET PRINTER” selected.
3. Hold down the Continue / Shift button.
The printer checks the Continue / Shift button at the end of self-test
or printer reset. If the button is held down, the printer enters the hex
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
Continue / Shift
button immediately after pressing the Set button. Try the above steps
once again.

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