Engineering Details Finally, any print jobs that are ahead of the RFU job in the queue are printed before the update is processed. Use one of the methods described in this manual to update the device firmware. Printer messages during the firmware update The following table lists the causes and results of possible interruptions to the firmware update. Table 7-2 Troubleshooting a firmware update Cause Result The job was cancelled from the control panel. No update has occurred. A break in the I/O stream occurred during send (for example, No update has occurred. the network cable was removed). A power cycle occurred during the RECEIVING UPGRADE No update has occurred. process. A power cycle occurred during the PERFORMING UPGRADE process. No update has occurred. Resend the update through a USB port. A power cycle occurred during the INITIALIZING process. The update has been completed. Print jobs that are sent to the device while an update is in process do not interrupt the update. All HP LaserJet devices leave the factory with the most recent firmware version installed. If a remote firmware update fails for the component, the .RFU file must be resent. The only component exception is the formatter. See Table 7-3 Update messages for information regarding a formatter update error. Because a firmware update cannot be resent over a USB for Mac, contact an HP Customer Care Center if a remote update fails in a Macintosh operating system. Three messages appear during a normal update process; others appear only if the update process does not succeed. Table 7-3 Update messages Device message RECEIVING UPGRADE Explanation This message appears from the time the device recognizes the beginning of an .RFU update until the time the device has verified the validity and integrity of the .RFU update. NOTE If the remote firmware update process is interrupted before the firmware is downloaded (while RECEIVING UPGRADE appears on the control-panel display), the firmware file must be sent again. No message appears on the device control panel to indicate that the update was interrupted. PERFORMING UPGRADE This message appears while the device is actually reprogramming the firmware. NOTE If power is lost during the flash DIMM update (while PERFORMING UPGRADE appears on the control-panel display), the update is interrupted and the message RESEND UPGRADE appears on the control-panel display.
