I did replace the Jet Direct card, problem hasbeen resolved
thnks full for your advice.
Check and remove the HDD and try it for a while. Replace the jet direct card and try (if you have one installed) and try. Update the firmware. If that fails then someone is sending a corrupt file\print job to the printer.
SOURCE: " 49.FF04 Error Turn off
Critical firmware error. Can be caused by invalid print commands, corrupt data, invalid operations or even electrical noise in the cable.
Turn off the printer, then turn it on.
Press Stop to clear the print job from memory.
Turn off and back on.
Print a document from a different software program.
If that document prints, go back to the first program that failed and print a different file.
If the error comes back, that file is corrupt.
If the message persists with different programs and print jobs have the formatter replaced.

EIO is the port for the network card on the back of the machine turn off machine remove card from EIO2 and install into EIO1 turn machine on and see what happens. If this does not work then open the formatter casing and remove the memory chips (OF COURSE WHEN THE MACHINE IS OFF) after removingone turn machine on and see if it boots up.
The 49 error is normally a software issue with the machine and it has locked within the network area or the memory.
Hope this helps you and please rate me
Cheers J

The 49 series errors are firmware errors, you may need a new formatter pcb.

These errors are almost always caused by outdated firmware. Print a configuration page and check the firmware version against this website . If your version is older than the one on HP's site then download the top option which is the easy install version and run it on your computer.
