Printing a Self Test
Running the printer’s self test helps you determine whether
the printer or the computer is the cause of a printing problem.
You can print the self test using either single sheets or
continuous paper.
Note:
Use paper that is at least 14.8 inches (376 mm) wide, such as
A3-size paper.
To perform a self test, follow these steps:
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.
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 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 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 the
Pause
button again.
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. See “Problems and Solutions” in your
User’s Guide for possible causes and solutions to the
problem.
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.
Note:
Use paper that is at least 8.3 inches (210 mm) wide, such as letter- or
A4-size paper.
To print a hex dump, follow these steps:
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.
2. To enter hex dump mode, hold down both the
LF/FF
and
Load/Eject
buttons while you press the
Operate
button to
turn on the printer.
3. Open a software program and send a print job to the
printer. Your printer prints all the codes it receives in
hexadecimal format.
If characters are printable, they appear in the right column
as ASCII characters. Nonprintable codes, such as control
codes, are represented by dots. 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.
4. To exit hex dump mode, press the
Pause
button to stop
printing and the
Load/Eject
button to eject the printed
page(s). Then turn off the printer.
