Hi,

This error occurs when the Control Panel can no longer communicate with the formatter. Loss of communication can occur due to one or more of the following causes,

• USB cable connection at the control panel

• Poor seating of the formatter

• Defective formatter

• USB cable connection at the ICB

  The communication path from the control panel to the formatter includes the Control Panel, USB cable, ICB, and the Formatter

  Follow these steps to try to resolve the issue and isolate the correct part

  1. Power off the product.

  2. Reseat the formatter.

  3. Reseat the USB cable connection at the rear of the control panel (rotate the control panel up 90 degrees for better access).

  4. Power on the product.

  5. If the error persists, check the Heartbeat LED on the formatter.

     If the Heartbeat LED is not flashing, replace the formatter.

     If the Heartbeat LED IS flashing, try again to reseat the formatter before replacing any parts.

  6. If the error persists after replacing the formatter, the control panel USB cable might not be seated properly at the ICB connection on top of the engine.

     Have the product serviced by an HP technician.

     NOTE: Do not ask a customer to check this connection; this procedure requires a technician to remove the back cover and the DC Controller shield.

  7. If the error persists replace Control Panel
