The following table lists possible reasons for the failure of a remote firmware upgrade and
the corrective action to take for each situation.
Reason for firmware upgrade failure
Corrective action
.RFU file corrupted The printer will recognize
that the file is corrupted and
will reject the upgrade.
Download the image from
the http://www.hp.com Web
site again and send the new
file to the printer.
Wrong printer model in .RFU file The printer will recognize
the model mismatch and will
reject the upgrade.
Download the correct image
from the http://www.hp.com
Web site and send it to the
printer.
Upgrade interrupted See previous table.
Flash hardware failure Although extremely unlikely,
the flash DIMM itself may
have a hardware failure. In
this case, order another
flash DIMM from HP.
NOTE: All HP LaserJet 8150 series printers ship from the
factory with the latest available firmware version installed
in a backup partition on the flash DIMM. If a remote
firmware upgrade fails, the printer can use the backup
firmware to reboot. You can then attempt the remote
firmware upgrade again.
