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,
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
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
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.
