I have 3 MX 922 printers. I am able to use them all wirelessly to print, and can use the first two to scan wirelessly, but I am unable to scan from the third one. When I go to the IJ utility to pick which scanner to use, it only gives me an option of two, unlike the printer where I have multiple options. The error message I get is that the computer is unable to communicate with the scanner check to see if it is turned on. (which it is). I use a portable MIFI to connect scanners 2 and 3. Number one is at home and goes through my home ISP's wireless.
