Epson ActionLaser 1600 Service Manual page 128

The ActionLaser 1600 has a sophisticated, built-in, self-diagnostic function that
reduces troubleshooting time by identifying failed parts or components. This
self-diagnostic test overcomes troubleshooting problems for page printers, in
which even a trivial failure can result in a serious print quality problem.
Self-Diagnostic Function
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 error message on the LCD panel.
Table 5-1 lists the messages that tell you if service maintenance is required.
