Front panel LED service mode error codes
Detected error conditions are displayed on the front panel as LED patterns. The
following table lists the service mode error codes which are displayed while the printer is
in service mode. (Service mode is explained in Chapter 9, “Checks and Adjustments.”)
These codes are more specific than the error codes displayed during normal operation
(see the previous topic “Rear panel). If an error occurs during normal operation, pressing
the rear panel TEST button causes the appropriate, and more specific, service mode error
code to be displayed on the front panel. The error codes listed below are explained in
greater detail in the Chapter 6 topic “Print engine error codes and their causes” on
page 6-19.
o means LED off
Z
