Hi mbelson,
You are correct, the PIXMA MP480 is not supported with Windows 10. You can try using an older driver. Please disconnect the USB cable and then follow these steps:
1. Press the Windows key on your keyboard and the letter R, then let both go.
2. In the Run window, please type CONTROL PANEL and click OK.
3. Click on View devices and printers (or Devices and printers, depending on your view).
4. Right click the Canon MP480 series and left click on Remove device. Repeat until all MP480's are removed.
5. In the upper left corner, click on Control Panel (or the Back button).
6. In Control Panel, click on Uninstall a program (or Programs and features, depending on your view).
7. Click once on "Canon MP480 series MP Drivers" and then click Uninstall at the top.
8. Follow the on screen prompts to uninstall the driver. When you click Complete, the driver is uninstalled.
