Reason for firmware upgrade failure
Corrective action
.RFU file corrupted The printer recognizes that the file is
corrupted and rejects the upgrade.
Download the image from the
http://www.hp.com/go/lj9000_firmware Web
site again and send the new file to the
printer.
Wrong printer model in .RFU file The printer recognizes the model mismatch
and rejects the upgrade. Download the
correct image from the
http://www.hp.com/go/lj9000_firmware Web
site and send it to the printer.
Upgrade interrupted See the previous table in this section.
Flash hardware failure Although extremely unlikely, the flash DIMM
itself might have a hardware failure. In this
case, order another flash DIMM from HP.
