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.
