Self-Diagnostic Function - Epson ActionLaser 1600 EPL-5600 Service Manual

5.1 OVERVIEW
The EPL-56W and ActionLaser 16Ml have a sophisticated, built-in, selfdiagnostic function that
reduces tmubkshooting time by identifying failed parts or components. This selfdiagrostic test
overcomes the tmubkshooting problems for page printers, in which even a trivial failure can result
in a serious print quality problem.

5.2 SELF-DIAGNOSTIC FUNCTION

This section describes the selfdiagnostic function in which the controller automatically dwcks the
operating conditions of each component. If any abnormality is detected, the printer displays an
error message on the LCD panel. Table 5-1 lists the messages that tell you if service maintenance is
required.
