Hi rastogim,
The MG6220 is not compatible with the 10.14 operating system. While Canon has not made drivers for this model for your operating system, we can attempt to install the drivers for an older version of Mac to see if it will work on your computer. Your unit is compatible with Mac OS X High Sierra v10.13 and below.
To install the drivers and software, please perform the steps below.
1. Disconnect the printer from the computer.
2. Click HERE to go to the printer's Downloads page.
3. Change the "Operating System" to "OS X High Sierra v10.13".
4. Download and install the "MG6200 series CUPS Printer Driver", "MG6200 series Scanner Driver" and "ICA Driver".
You may also try a third-party driver interface called VueScan from Hamrick Software (https://www.hamrick.com/download.html). When you go to their Downloads page, the page will automatically download a Free (limited) version. Please keep in mind that VueScan is a third-party software, which Canon does not guarantee in any way. Additionally, Canon will not be able to offer support for the scanner while being used with the VueScan software.
You are also eligible for the Canon Upgrade Program. This is for out of warranty units which have been diagnosed to require service or are incompatible with a new or upgraded system. This program allows you the opportunity to purchase a replacement product discounted from the list price. We will also include free ground shipping with your purchase.
If you would like to take advantage of this offer, please call our Sales Department at (866) 443-8002 seven days a week, 8 AM to midnight EST. Let them know you have been working with email technical support and that the Canon Upgrade Program was offered.
