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