Inflate Failure 1

[iolair]

Hello,
We have a Color LaserJet 4700 that is displaying the following message : "Inflate Failure RFU Upgrade on Parallel Port" which then changes, in about three seconds to "Download File Now Send RFU Upgrade on Parallel Port". I have searched on HP's website and have found that it's looking for a firmware update. I did not ask it to update the firmware. I have an even bigger problem, as this printer has no parallel port at all, only a USB port. And none of the front panel buttons are responsive. I have cycled the power on this unit several times to no avail. Has anyone ever encountered this before, and is it repairable?

Thanks.

Yes! I have just done this on a 4650 unit with the same trouble.
1}Go to HP, and select drivers. Select your unit, then scroll down past the drivers to the "Other O/S" area.
This will be the RFU file you need.
2} This is compressed, so run it, and then click on the .exe file. This will change it to an RFU file with only one underscore, and the rest with dots.
3} Open a dos box, {start, run, type in "cmd".}
4} Go to the directory the file is in, and type:
copy /b "name of file" "the name of your USB port".
5}The unit will re-boot and if you see the HP logos, it will continue to ready.
If this is not working,You will have to order a new firmware compact flash chip and repeat this.

Thanks! I was able to follow your instructions, but unfortunately, the chip is bad. HP is sending a new one. Thanks. I'll keep this in my "how to" file.
