HP Laserjet 4200n with a 49.4c02 service error

Hi
I have a HP LJ 4200n (not covered under warranty) with a 49.4c02 service error.
This error message displays during some printjobs but when I power off the printer and turn it back on it prints just fine and even allows the print jobs that were held in queue to print.

Any assistace will be greatly appreciated.

Thanks
Giovonna

Appears to be firmware error.
You may have to replace the firmware DIMM.

Google the error and you'll see a bunch of stuff to try.
