Description
If the     lights green, the printer is ready to print. 
If the     lights red, the printer is experiencing an error, 
such as jammed paper, the open cover or the empty toner 
cartridge. See “Troubleshooting Error Messages” on page 
6.18. 
If you press the     button while the printer is receiving 
data, the  
 
LED blinks red to cancel printing.
In Manual Feed mode, if there is no paper in the Manual 
Feeder, the    LED blinks red. Load paper into the Manual 
Feeder and the LED stops blinking. 
If the printer is receiving data, the     LED slowly blinks 
green. 
If the printer is printing the received data, the     LED 
blinks green fast.
