Troubleshooting
Printing a Self Test
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. See “Problems and Solutions” for possible causes
and solutions to the problem.
You can print a self test 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 (9.5 inches) wide or A4 or
letter size single-sheet paper.
To perform a self test, follow these steps:
1. Make sure paper is loaded and the printer is turned off.
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 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 near-letter-quality test.
