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.
