Printing a Self Test

Running the printer’s self test helps you determine whether the problem comes from the printer or the computer:

TIf 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.)

TIf the self test does not print properly, there is a problem with the printer. See “Problems and Solutions” on page 8-7 for possible causes and solutions to the problem.

To perform a self test, follow these steps:

1.Make sure that the printer is turned off and that the paper is set on the front or rear tractor. (See Chapter 3 for more information on loading and using paper.)

c Caution:

Whenever you turn off the power, wait at least five seconds before turning it back on; otherwise you may damage the printer.

2.While holding down the LF/FF Load or Tear Off button, turn on the printer. The LF/FF Load button performs a draft self test. The Tear Off button performs a near letter quality (NLQ) self test.

In a few seconds, the printer starts the self test, in which a series of characters is printed.

Note:

If you want to temporarily stop the self test, press the Pause button. To resume the test, press the Pause button again.
