HP Jetdirect LEDs

The embedded HP Jetdirect print server has two LEDs. The yellow LED indicates network activity, and
the green LED indicates the link status. A blinking yellow LED indicates network traffic. If the green LED
is off, a link has failed.

For link failures, check all of the network cable connections. In addition, you can try to manually configure
the link settings on the embedded print server by using the MFP control-panel menus.

Heartbeat LED

The heartbeat LED indicates that the formatter is functioning correctly. While the MFP is initializing after
you turn it on, the LED blinks rapidly, and then turns off. When the MFP has finished the initialization
sequence, the heartbeat LED pulses on and off.

If the heartbeat LED is off, the formatter might have a problem. Contact an HP-authorized service or
support provider. See the HP support flyer, or go to
