What does the Status LED color indicate on the SCX-4200?

When the Status LED is green and steady, the machine is on-line and ready to use. When it is off, the machine is either off-line or in Power Save mode and will switch on automatically when data is received or a button is pressed. A slowly blinking green light means the machine is receiving data from the computer, while a normally blinking green light means it is scanning a document. A red Status LED indicates a problem such as an empty toner cartridge. (Page 9.3)
