Engineering Details The elapsed time for an update depends on the I/O transfer time, as well as the time that it takes for the MFP to reinitialize. The I/O transfer time depends on a number of things, including the speed of the host computer that is sending the update and the I/O method (network). The reinitialization time depends on the specific hardware configuration of the MFP, such as the number of EIO devices installed, the presence of external paper-handling devices, and the amount of memory that is installed. 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 MFP firmware. Printer messages during the firmware update The following table lists the causes and results of possible interruptions to the firmware update.

The elapsed time for an update depends on the I/O transfer time, as well as the time that it takes for the
MFP to reinitialize. The I/O transfer time depends on a number of things, including the speed of the host
computer that is sending the update and the I/O method (network). The reinitialization time depends on
the specific hardware configuration of the MFP, such as the number of EIO devices installed, the
presence of external paper-handling devices, and the amount of memory that is installed.
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 MFP firmware.
Printer messages during the firmware update
The following table lists the causes and results of possible interruptions to the firmware update.
Table 6-2
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,
the network cable was removed).
No update has occurred.
A power cycle occurred during the
RECEIVING UPGRADE
process.
No update has occurred.
A power cycle occurred during the

No update has occurred. Resend the update through a USB
port.
A power cycle occurred during the

process.
The update has been completed.
Print jobs that are sent to the MFP while an update is in process do not interrupt the update.
All HP LaserJet MFPs 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

Update messages
on page

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 6-3
Update messages
Device message
Explanation
RECEIVING UPGRADE
This message appears from the time the MFP recognizes the beginning of
an .RFU update until the time the MFP 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 MFP
control panel to indicate that the update was interrupted.
PERFORMING UPGRADE
This message appears while the MFP is actually reprogramming the firmware.
