Applicable To


Resolution / Answer

Link/Activity Indicator (Green)

Off No Link (Disconnected)
On Network Link has been established
Blinking Network Activity has been detected

Speed Indicator (Orange)

Off No Link (Disconnected)
1 Blink The LED blinks once (one blink, pause, one blink. etc) when a 10Base Link has been established
2 Blinks The LED blinks twice (two blinks, pause, two blinks. etc) when a 100Base Link has been established

If both LEDs are off, the printer has not detected the presence of a network cable. 

To solve the problem follow these 4 steps:

  1. Verify that the network cable is appropriate and has an RJ-45 connector.
  2. Remove the network cable from the printer. Plug the network cable back in until you hear a positive click.
  3. Check the other end of the cable in the same manner. If the printer still does not detect a cable, then continue.
  4. Connect the printer to a known good network. If the printer is still unable to detect the network cable, contact Technical Support for assistance.
