Device message
Explanation
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 MFP has finished reprogramming the
flash until the MFP 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 becomes corrupted). Perform another update by any means that
is supported by the MFP, regardless of the connection (network or USB).
RFU LOAD ERROR
SEND RFU UPGRADE
ON USB PORT
This message appears (in English only) if the firmware update of the formatter
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 USB port of the MFP.
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.
The following table lists possible reasons for the failure of a remote firmware update and the corrective
action required for each situation.
Table 6-4
Troubleshooting a firmware update failure
Reason for firmware update failure
Corrective action
The .RFU file is corrupted.
The MFP recognizes that the file is corrupted and rejects the update. Download the
file again and send the new file to the MFP. Download the file from
www.hp.com/
go/cljcm4730mfp_firmware
.
The wrong MFP firmware is contained in
the .RFU file.
The MFP recognizes the MFP mismatch and rejects the update. Download the
correct file and send it to the MFP. Download the file from
www.hp.com/
go/
cljcm4730mfp_firmware
.
The upgrade was interrupted.

.
A flash hardware failure occurred.
Although it is extremely unlikely, the MFP might have a hardware failure. Call
technical support to address the problem (see the flyer that came with the MFP for
a local telephone support list). Or see the following:

Remote firmware update by using an executable RFU files
Complete the following steps to update the product firmware by using an executable RFU downloaded
from the Web.
NOTE:
Use this process to update the firmware on network or USB connected devices.
1.
Download the executable RFU file from the following Web site:
www.hp.com/
go/
cljcm4730mfp_firmware
2.
Run the executable on the PC to extract the RFU file and Readme document.
3.
Run the RFU file.
