Table 2-8 Troubleshooting a firmware update failure
Reason for firmware update failure Corrective action
The .RFU file is corrupted. The product recognizes that the file is corrupted and rejects the update.
Download the file again and send the new file to the product. Download the file
from
www.hp.com/go/lj2410_firmware for the HP LaserJet 2410 printer,
www.hp.com/go/lj2420_firmware for the HP LaserJet 2420 printer, or
www.hp.com/go/lj2430_firmware for the HP LaserJet 2430 printer.
The wrong product is contained in
the .RFU file. The product recognizes the printer mismatch and rejects the update. Download
the correct file and send it to the product. Download the file from
www.hp.com/go/
lj2410_firmware for the HP LaserJet 2410 printer, www.hp.com/go/
lj2420_firmware for the HP LaserJet 2420 printer, or www.hp.com/go/
lj2430_firmware for the HP LaserJet 2430 printer.
The upgrade was interrupted. See Troubleshooting a firmware update .
A flash hardware failure occurred. Although it is extremely unlikely, the product might have a hardware failure. Call
technical support to address the problem (see the flyer that came with the
product for a local telephone support list).
NOTE All HP LaserJet products leave the factory with the most recent firmware version
installed. If a remote firmware update fails, the .RFU file must be sent over a parallel port
connection.
