Printing A Self Test - Epson DLQ-3500 Reference 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 4-3 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 1-7 or "Loading
Single Sheets" on page 1-18 for paper-loading instructions.
Follow these steps to perform a self test:
1. Make sure paper is loaded, and the proper paper source is
selected on the control panel. Then turn off the printer.
c
2. To run the test using the Draft font, turn on the printer while
holding down the LF/FF button. To run the test using the
printer's letter-quality fonts, turn on the printer while holding
down the Load/Eject 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.
After a few seconds, the printer loads the paper automatically
and begins printing the self test. A series of characters is
printed.
Caution:
Whenever you turn off the printer, wait at least five seconds
before turning it back on; otherwise you may damage the
printer.
