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 in an MS Windows operating system, the .RFU file must be resent.
If a remote firmware update fails in a Macintosh operating system, contact support from an HP Customer
Care Center.
The following table lists possible reasons for the failure of a remote firmware update and the corrective
action required for each situation.
Table 7-8 Troubleshooting a firmware update failure
Reason for firmware update failure Corrective action
The .RFU file is corrupted. The device recognizes that the file is corrupted and rejects the update. Download
the file again and send the new file to the device. Download the file from
www.hp.com/go/lj5200_firmware.
The wrong device is contained in
the .RFU file.
The device recognizes the printer mismatch and rejects the update. Download the
correct file and send it to the device. Download the file from
www.hp.com/go/
lj5200_firmware.
The upgrade was interrupted. See Table 7-9 Update messages.
A flash hardware failure occurred. Although it is extremely unlikely, the device might have a hardware failure. Call
technical support to address the problem (see the flyer that came with the device
for a local telephone support list).
Three messages appear during a normal update process; a fourth (RESEND UPGRADE) appears only
if the update process does not succeed.
Table 7-9 Update messages
Printer message Explanation
RECEIVING UPGRADE 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.
INITIALIZING This message appears from the time the device has finished reprogramming the
DIMM until the device reinitializes.
