Printing a Self Test
Running the printer’s self test helps you determine whether
the problem comes from the printer or the computer:
❑
If the self test results are satisfactory, the printer is working
properly and the problem is probably caused by 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” for possible
causes and solutions to the problem.
You can run the self test with either single sheets or continuous
paper. This section describes how to run the test with
single-sheet paper. See Chapter 3 for information on loading
and using continuous paper.
To perform a self test, follow these steps:
1. Make sure paper is loaded in the paper guide or on the
tractor, and the paper release lever is set to the correct
position for your paper. Then turn off the printer.
c
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 self test
prints faster than the letter-quality test. See pages 4-5 and
4-6 for more information on using fonts.
