LEDs
LED 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, no paper, the open top or front cover, 
or the empty toner cartridge.
See “Troubleshooting Error Messages” on page 5.17. 
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 tray, the 
 LED blinks green. Load paper into the tray 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.
