Pixma MG5550 scan suddenly stopped work

[macguy14]

I scanned last week. Today I tried to scan, with nothing havng been changed, and now it doesn't work. I receive error code messages.

Code:15,157,1

The wifi, the router, the passwords are all fine. The signal is 100%. The router appears in printer display. The Wifi is on on the computer. Just the macbook 10.9.4 OS X says 'searching for scanning device'  and then I get the code message...

It does print via wifi....so it is something just with the scanner.  Printer is a few months old...

Just started working again...no idea why. didn't do anything.

'Forced QUIT' the application instead of letting it close on its own when you normally click 'close' or 'try again'. and then it was working again.
