ColorLaserjetPro mfp m479fdw won't respond at all

I bought this printer in September, and now it won't respond at all. I have disconnected all power and ethernet cords on both ends, and let it sit over the weekend, but still when I turn it on it the screen will come on and it will power up as normal, but then it ceases to do anything other than continually power up and power down. The screen is unresponsive, it won't print, copy, or scan. If I enter a flash drive, it opens the memory device option screen, but it won't let me select any of those options. Even the back, home, and question mark buttons at the bottom of the screen are unresponsive. When I print to it, the job stays in the print que, with a status of error - printing. I have tried pressing on the bottom right corner of the screen to re-set it to factory settings, and it didn't change anything in the way it booted up.

Prior to this, it has randomly started cycling up and down, and occasionally it would re-set itself to its' original settings (French, I believe), and I would have to re-set the language, date, and time. It was a store model; I don't know if that has anything to do with it.

I've tried the print and scan dr., and it tells me that the device is not connected, but it is. I have unplugged and re-plugged everything multiple times, and downloaded new drivers.

Does anyone have any ideas? I'm stuck! Thanks so much!

I got it to work! If anyone else has this problem, I did a variety of things. Not sure which one fixed it, but here's what I did in the order I did it...I disconnected everything on every end. Power cord at wall and printer. Ethernet cord at printer and cpu. Deleted the printer drivers. Complete shutdown and restart on CPU. Reinstalled the printer drivers. Plugged everything back in. When I turned on the computer, I covered the bottom right corner of the printer screen with 3 fingers (I had read in one of the forums that was how to re-set the printer. I tried it before with one finger, and it didn't help, but I wasn't sure how much space to cover either...so I tried 3 fingers). When it came up, it copied right off. Printed a test page and it worked. IDK...I was about ready to throw it out, but now it works like new. WHEW!
