Product: HP DesignJet Z6200 42-in Photo Production Printer

Tried to update firmware to KHN_03_07_07.1   but always says invalid file.  I have a fat32 usb drive and I have only that file on it.  I found an old firmware file on some random website and it updated but its still is an old firmware. How do I get this file?
