Hello Jerry, and welcome to justanswer.com, my name is ***** ***** I will do my best to assist you.
Personally, Im a fan of salvaging printers. While it sounds like your scanner motor has failed on the printer you have, the printhead, control panel and other parts still have service life left on them.
So one possibility would be to purchase the same identical model, that way you can continue to use your ink you have for that printer, and more importantly you will have a second working printhead you can scavenge when the printhead fails. For instance, here is the same model of printer you already have, the mx 922. http://amzn.to/1QLmJgw And here is the cost of the printhead. http://amzn.to/1Lj3OY2
So even though the scanner has failed, the printhead inside your current unit is still worth 50$ ( the cost to replace it ) And if you have even one set of ink you have close to 100$ of value in your non functioning printer.. Those parts would be useless to you if you go with a different model of printer.
And thats the reason I am suggesting replacing it with the same model.
Now with that being said, since theres no firmware update for your model. And since theres no user replaceable parts for the scanner itself. Theres really only one move we can make here.
Forget about network scanning for a moment.
If you insert a document on the scanner glass and press the copy button on the machine itself, will it allow you to make a copy?
If not, then the scanner has failed.
If it will allow you to make a copy, then the error is something we can fix.
When you have had time to read over and digest my response Jerry, youre welcome to get back to me and we can discuss this further.
