I have a Pixma TR8500 and a TR 4520 at a different location. When I try to scan from my 4520 the IJ scan Utility lists the 8500. The IJ Scan Utility comes up with the 8500 printer so I click select which takes me to the Network scanner which lists both printers. I click on the 4520, but the choice on the selector remains the 8500. How do I change the selected scanner?
