It worked last week &amp; also my son just bought a new computer, &amp; it works for wireless printing but not the mp navigator. Could it be windows 8.1? The message we get is the scanner is turned off or disconnected, cannot communicate with printer.</P> Tue, 24 Jun 2014 14:14:23 GMT joejoe57 2014-06-24T14:14:23Z https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/MP-Navigator/m-p/100574#M33323 <P>Mp Navigator 2.1 stopped working.
