The 79:04 Error is a generic one, so the printer doesn't exactly know what is happening. If this is happening only while processing a job there is a possibility that the formatter is defective however my suggestion is to try printing a different job and if the same happens then make sure that the driver is the latest one and check the status of the printheads and cartridges.

I agree with @HarryCR try printing a different print job to see if you get the same errors. Could be a corrupted print job.

Hi to all...just an update...I have proven that the error only appears when a job is sent across the network..by that I mean with the network cable disconnected you can boot and all internal and any usb printing is fine....so I am thinking next culprit network card..or formatter..I will update as I go.

If the printer gets ready and you can print without the network cable connected that means that the Nic, network card or jetdirect is defective, and definitely is not a printhead issue @piano999 because the machine prints fine when disconnected from the network. @perthblue1960 I suggest you don't replacing any printheads if from usb or internally the machine works fine.
