Won't power up

Since you have multiple items that are damaged from the power issue, this is an insurance claim.. It would appear that there was a surge that damaged the power supplies.

I had a similar problem with my Bosch wall oven after a recent power outage-restart-outage-restart cycle that lasted only about thirty seconds altogether. The difference would be in that while I could reset all the things like day, date, time, etc., the oven would arbitrarily go off on its own and make up the day, time, date, year, etc., with no apparent correspondance to reality. Here's what I did: I completely shut down the oven at its outside breaker (you will need to do whatever it takes to remove the power from the 'plug-n-go'). I waited five or ten minutes before turning the power back on and resetting the various items. Two days have passed and there have been no more mind-of-its-own excursions into another time zone. Problem solved, unless/until another power outage cycle comes along. Hope this helps, or at least gives you an idea about where to start.

Electrical power users are these days more concerned about quality and reliability of power supplies for critical operations. These concerns were to the fore in the recent power outages due to storms. Modern electronic equipment is also susceptible to voltage sags, swells, transients and distortion prevalent on many power circuits. Industrial sites experience more serious disturbances than commercial and residential sites, due to the negative impact of machinery and equipment on load power quality.

Try rebooting the printer (switch it off for a few seconds, turn it back on).

Try another Ethernet card (adapter) for the PCI slot. The onboard adapter maybe "shot".

Check your breakers in the Main Panel for your electrical control of your house.
Make sure you are getting 220Volts at the receptical, and where the wire connects to the back of the dryer, sometimes the wire will burn loose at that connection

The cause is the power-supply "brick" to the DI-514.
It has failed.

So, it's time to buy a "surge-suppressor" (sometimes integrated into a high-end power-bar) and to buy a new router, for less than $80, in total, to be protected and be ready for the "next" storm.

Looks like the electronic micro controller fault.Due to power surge this could have resulted. It is bad luck!

If you haven't seen it yet, here is a page that may help with a manual or parts list.

This problem sounds kind of bad, generators don't do well when the engine stops under load.
Start by checking the circuit breakers in the distribution box (outlet panel) - you need ot do this with an ohm meter. After that check the power windings of the stator with the ohm meter, be sure to check between the 2 windings (should be open), and from each one to ground with the winding isolated.
Whining, a burning varnish smell, and breakers that trip all the time are indicators of long term overload problems. This could happen if you had most of the load on one winding for a significant amount of time, or if the one winding mostly powered motor-like loads with high startup currents.

You may want to look at this answer I posted some time ago.

Check the print processor settings in the advanced tab of the printer properties. This should be set to Winprint, and not anything else.
