After a few seconds, the printer loads the paper automatically 
and begins printing a self test. A series of characters is printed.
Note:
To temporarily stop the self test, press the 
Pause button. To resume 
the test, press the 
Pause button again.
3. To end the self test, press the Pause button to stop printing 
and the Load/Eject button to eject the printed page. Then 
turn off the printer.
Printing a Hex Dump 
If you are an experienced user or a programmer, you can print a 
hexadecimal dump to isolate communication problems between 
the printer and your software program. In hex dump mode, the 
printer prints all data received from the computer as hexadecimal 
values.
You can print a hex dump using either single sheets or continuous 
paper. See Chapter 2 for instructions on loading continuous 
paper, or Chapter 3 for instructions on loading single sheets.
Note:
Use continuous paper that is at least 241 mm (9.5 inches) wide or A4 or 
letter size single-sheet paper.
To print a hex dump, follow the steps below.
1. Make sure paper is loaded and the printer is turned off.

Caution:
Whenever you turn off the printer, wait at least five seconds 
before turning it back on; otherwise you may damage the 
printer.
