Running the printer’s self test helps you determine whether the 
printer or the computer is causing the problem:

❏

If the self test results are satisfactory, the printer is working 
properly and the problem probably results from your 
printer driver settings, application settings, computer, or 
interface cable. (Be sure to use a shielded interface cable.)

❏

If the self test does not print properly, there is a problem 
with the printer. 

You can print the self test using either single sheets or 
continuous paper of at least the following width:

Follow these steps to perform a self test:

1. Make sure paper is loaded and the printer is turned off.

2. To run the test using the Draft font, turn on the printer 

while holding down the 

LF/FF

 button. To run the test 

using the printer’s near letter-quality fonts, hold down the 

Load/Eject

 button while you turn on the printer. Either self 

test can help you determine the source of your printing 
problem; however, the draft self test prints faster than the 
near letter-quality test.

After a few seconds, the printer loads the paper 
automatically and begins printing the self test. A series of 
characters is printed.

Note: To temporarily stop the self test, press the Pause button. 
To resume the test, press Pause again.

3. To end the self test, press the 

Pause

 button to stop 

printing. If paper remains in the printer, press the 

Load/Eject

 button to eject the printed page. Then turn off 

the printer.

Caution: Do not turn off the printer while it is printing the self 
test. Always press the Pause button to stop printing and the 
Load/Eject button to eject the printed page before you turn off 
the printer.

The hex dump feature is designed for DOS-based PC 
connections. 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 it receives from the 
computer as hexadecimal values.

You can print a hex dump using either single sheets or 
continuous paper that is at least 8.3 inches (210 mm) wide, 
such as A4 or letter size paper.

1. Make sure paper is loaded and the printer is turned off.

2. To enter hex dump mode, turn on the printer while holding 

down the 

LF/FF

 and L

oad/Eject

 buttons.

3. Open a software program and send a print job to the 

printer. Your printer prints all the codes it receives in 
hexadecimal format, such as:

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. If characters are printable, 
they appear in the right column as ASCII characters. 
Nonprintable codes, such as control codes, are represented 
by dots.

4. To turn off hex dump mode, press the 

Pause

 button, eject 

the printed page(s), and then turn off the printer.

Caution: Do not turn off the printer while it is printing the hex dump. 
Always press the Pause button to stop printing and the Load/Eject 
button to eject the printed page before you turn off the printer.

To reset the printer’s EEPROM, hold down the 

Load/Eject

, 

LF/FF

, and 

Pause

 buttons while turning on the printer. The 

printer beeps once, and restores its factory default settings.
