5.1 OVERVIEW
The EPL-3000 and ActionLaser 1300 have a sophisticated, built-in, selfdiagnostic function that
reduces troubleshooting time by identifying failed parts or components. This selfdiagnostic test
overcomes the troubleshooting problems for page printers, in which even a trivial failure can result
in a serious print quality problem.

This section describes the self-diagnostic function in which the controller automatically checks the
operating conditions of each component. If any abnormality is detected, the printer displays an
e&or message on the LED. It enables repeat displays as follows.
