Illumination and meaning
To be able to indicate a large number of status situations both
individually and in combination, the LEDs are illuminated as
follows:
The Status Monitor in Windows provides a readable description
of the printer status corresponding to the indications of the
LEDs. In Mac, the printer driver provides status information
once you have sent a document to print. In Windows, if you
have the Status Monitor Preferences set to Pop up on alerts,
this readable message will be presented on screen whenever
an abnormal condition occurs. See
for more information.
