MG6220 - macOS Monterey - Failed to open a connection to the device (-21345)

Hi,

I just bought a new MacBook M1 Pro and cannot get the MG6220 scanner to work. The printer is connected via WiFi. I have seen threads where it is suggested that disabling IPv6 is the solution. Where and how do I make this change? Is this the best solution?

Any help would be much appreciated.

Thank you,

Howard
