Printing A Self Test - Epson LQ-690II User Manual

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 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" on page 76 for possible causes and solutions to the problem.
You can print the self test using either single sheets or continuous paper. See "Loading Continuous
Paper" on page 33 or "Loading Single Sheets" on page 39 for paper loading instructions.
Note:
Use paper of at least the following width:
Continuous paper
Single sheet
Follow these steps to perform a self test:
1. Make sure paper is loaded and the paper release lever is set to the correct position.
Then turn off the printer.
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, turn on the printer while holding down the d button. To
run the test using the printer's letter quality fonts, turn on the printer while holding down the
u button. 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.
3. When using single sheet paper, load paper in the printer.
After a few seconds, the printer loads the paper automatically and begins printing the self test.
A series of characters is printed.
