HP Color LaserJet 451dn: 'Firmware Corrupt, Ready 2 Download'

HP Recommended
LasjerJet 400 Pro, Model 451dn
Linux

Hi everyone,

 

I (used to) have a perfectly working HP Color LaserJet 400 Pro Series (Model 451dn).

The printer was networked using Ethernet and I could print fine from the Windows, OSX and Linux boxes in my home.

It was working fine until I tried updating the firmware last sunday and it lost power while it was 'Erasing...' (ouch)

 

Sure enough, when the power came back, the printer was non-functionnal, had lost all of its settings and displayed that infamous message:

 

"Firmware Corrupt, Ready 2 Download".

 

I tried a few things in hope that I would be able to recover the printer:

 

Attempt #1)

- Disconnected Ethernet, connected the printer though USB to a Windows 10 PC (the one I had been flashing from).

- Created a new USB printer.

- Attempted to flash the printer again

- No result, the printer's display didn't even blink.

 

Attempt #2)

- with the printer turned off, run the flash utility -again- and send the firmware payload to the USB-defined printer.

- Once the full firmware was sent to the spooler, turn the printer on.

The printer showed 'Downloading...' quickly (about 1 second) and went to 'Erasing...' with a dark Orange LED light on.

It stayed like this 'Erasing...' for several hours.

 

Interestingly, when I first connected the printer to the Windows Computer using the USB cable., a completely different printer showed up on the USB Bus: an HP Laserjet 3020 (I've never owned any of these). I was able to confirm that it was my Laserjet 451dn that thought it was a Laserjet 3020.

 

Any ideas?

 

Is it worth attempting to get the printer repaired? Can it be repaired?

 

Thanks for reading,

Vincent

Hi, 

 

Install the HP Universal Printer PCL6 driver, 

 

While your printer is at OFF

 

Install manually (Windows Add Printer) the printer via USB with the PCL 6 driver

 

Open the HP Utility Firmware Update and send it to the printer.

I have the same issue, after start the firmware update.

"The printer showed 'Downloading...' quickly (about 1 second) and went to 'Erasing...' with a dark Orange LED light on.

It stayed like this 'Erasing...' for several hours."

How it can be solved?
