Heartbeat LED

The heartbeat LED provides information about product operation. If a product error occurs, the

formatter displays a message on the control-panel display. However, error situations can occur causing

the formatter to control panel communication to be interrupted.

HP recommends fully troubleshooting the formatter and control panel before replacing either

assembly. Use the heartbeat LED to troubleshoot formatter and control panel errors to avoid

unnecessarily replacing these assemblies.
