Hi DCMoneague,
Reinstalling will resolve this error.
First, let's reinstall the drivers. Please turn your PIXMA G7020 off and disconnect the USB cable and then follow these steps:
1. On your computer, please press the Windows key on your keyboard and the letter I, then let both go.
2. Click on "Bluetooth & devices" on the left side.
3. On the right side, click on "Printers & scanners".
4. Click on the Canon G7000 series. In the new window, click "Remove" at the top.
5. Repeat until all G7000's have been removed from the Printers list.
6. Close the Printers window once complete.
7. Turn your computer off. Once off, please turn it back on.
Next, we will download the latest driver:
1. Please click this link: Canon Support for PIXMA G7020 - Downloads
2. Click on Software & Drivers.
3. Choose "Windows" from the Operating System drop down and then "Windows 11" from the Version drop down.
4. Click the Download button to the right of "Print Driver and Scan Utility Installer Ver.1.00 (Windows)". Note: you may have to click the "Load More" button to locate this.
5. Once that file finishes, please open or run that file to begin the installation on your computer. If you have to search for the file first, the files name is: "md__-win-g7000-1_00-ea34_2.exe"
6. Follow the on screen prompts to reinstall. Please do not turn your printer back on and reconnect the cable until the installation prompts you to.
Once reinstalled, please attempt to scan with the IJ Scan Utility.
