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

holding down the LF/FF Load button. To run the test using 
the printer’s NLQ font, hold down the Top of Form 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 NLQ test.

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

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. 

Tear off the page if necessary, and 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 then 
turn off the printer.

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.
