HP LaserJet P4010 and P4510 Series - Software Technical Reference

The following table lists possible reasons for the failure of a remote firmware update and the corrective
action required for each situation.
Table 6-2 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/ljp4010series_firmware and www.hp.com/go/
ljp4510series_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/
ljp4010series_firmware and www.hp.com/go/ljp4510series_firmware.
The upgrade was interrupted. See Table 6-3 Update messages on page 244.
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; others (RESEND UPGRADE and RFU LOAD
ERROR) appear only if the update process does not succeed.
Table 6-3 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.
RESEND UPGRADE This message appears (in English only) if the firmware update fails because the
RFU process is interrupted. It can also occur if firmware for accessories (such as
the duplex unit or an output device becomes is corrupted. Perform another update
by any means that is supported by the printer, regardless of the connection
(network, parallel, or USB).
RFU LOAD ERROR
SEND RFU UPGRADE
ON PARALLEL PORT
This message appears (in English only) if the firmware update fails because the
print-engine firmware is corrupted.
If this message appears, the update must now be sent only by a computer that is
attached to the parallel port of the device.
NOTE: To verify that the firmware update succeeded, print a new configuration page from the control
panel and verify that the firmware date code on the configuration page has changed.
