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.
NOTE:
HP recommends fully troubleshooting the formatter and control panel before replacing either
component. Use the hjeartbeat LED to troubleshoot formatter and control panel errors to avoid
unnecessarily replacing these components.
