2. To run the test using the Draft font, hold down the LF/FF
button while you press the Operate button to turn on the
printer. 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 test prints faster
than the near-letter-quality test.
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 wide or A4 or letter size
single-sheet paper.
