How to fix the error "Firmware corrupt - ready 2 download" in a Laserjet pro 400 color 451nw

[JenWal131]

Hi we have a Laserjet pro 400 color 451nw and while upgradeing of the firmware the powercabel fell out.

The printer now says Firmware corrupt - ready 2 download, when we plug it into a computer (win7 64) it displays as a laserjet 3020 and the only driver that installs is Printing support.

We tried to boot it up while holdning left arrow and cancel but it goes straigt to the error message.

Any ideas how we can fix it?

Regards

you can try to reload the firmware again but typically when an upgrade is interrupted, there may be no recovery other than to replace the formatter board.

I had the same problem. HP tech suggest, after trying a number of fixes, that I have the logic board replaced.

I didn't have to. I stumbled on a solution. Then a power drop brought it back. I went back to my accidental fix and was able to restore operations.

The 3020 is a false assumption and should be deleted, even if the fix works.

Hope this works for you. (Since my last post, I had the same problem with another power drop and solved it by following the steps outlined in the Solution. Since I needed a new Yellow cart I followed the procedure. I never was able to install the firmware update and the printer still outperforms most of the later printers when it comes to color rendering for subtle color shifts, including flesh tones.)

Since the computer registers the printer as a diffrent model and as a device, its not possible to resend it.

Not necessarily so. Before posting my response to JenWal131 - I had just booted up and tried to print an email. The churning, spinning beach ball appeared. I let it run its course and opened System Preferences, to Printers & Scanners. More beach ball. Open, and the unwanted printer was there. I simply deleted it, reboot, with Command+Option+P+R, and the proper printer appeared.

True, if you try the solution I posted and initialization of a toner cart occurs then the priner should be on line. Since the "Firmware corrupt..." takes the printer off line and the green status light will not light up, the unwanted printer is simply unrelated to the off line 400.

I have previusly deleted the unwanted printer as well as the drivers connected to it with out any change in model, however i will try to to change toner as soon as i get my hands some.
