I just set up our PIXMA MX922 All-In-One Printer. The printer works fine, but I cannot get the scanner to work. The Printer connected to the wifi network and the computer discovered the printer and installed it. However, when we open the scanner, a blank box pops up. With our old Canon printer the box would open and display an image of what was on the scanner. Our operating system is Mac OS 10.13 High Sierra.
Thanks in advance.
