Product: HP LaserJet Pro 400 MFP M425dn
Operating System: Microsoft Windows 7 (64-bit)

I'm trying to update the firmware of the HP LaserJet Pro 400 MFP M425dn, from a networked Windows 7 PC, which has the latest HP drivers installed, and can to print to and scan from the printer. The printer/scanner/fax are all working fine...

 

The latest driver update I've downloaded is...

 

http://ftp.hp.com/pub/softlib/software13/FW_CPE_Commercial/Sun_MA/M425_MFP_Series_FW_Update-20171205...

 

I've switched off/on the printer

Run the firmware update on the PC

Selected the M425dn printer... either the fax driver or PCL6 driver (tried both)

And sent the firmware update

 

The printer control panel temporarily changes to say "HP - printing document" for around 4 seconds, then reverts back to the standard menu screen.

 

The progress bar of the firmware update showing on the the Win7 PC completes after around 60 seconds, with a yellow smiley.

 

But when you check the firmware version installed on the M425dn printer, it still shows the original firmware datecode: 20130415.

 

From the firmware installation instructons, it seems to suggest the printer control panel should show an 'updating' screen during the update. I've tried selecting the other fax driver in the firmware update, with no success.

 

FYI... we suspect this printer could have been affected by a virus... one morning we came in to find it had various games installed within the menu? ...firmware version is obviously old.

 

Any advice really appreciated...

We have found a solution to the problem (if it helps anybody else).

 

HP telephone support were able to provide us with a way of hard resetting the printer firmware to a basic raw setting, by using particular pressure on areas of the control panel immediately after the printer was turned on. It was a bit fiddly to achive, and I had to have several attempts, but eventually I got pressure to the right areas of the control panel, and the existing firmware was overwritten with some basic firmware.

 

After doing that, it was possible to follow the standard instructions (above) to install the firmware update via a network connection, the update worked perfectly.

 

Whether the printer firmware had been compromised by malicious software in the past is unclear, for a period of time the printer was showing games on it's control panel - such as Solitaire.

 

Top marks to HP for spending an hour on the phone to help us solve the update problem
