Think you may find that W10 itself will sort out the driver issue, if there is one, with it's own generic drivers once it recognises the printer's presence.
Canon say this about the 620.
"Canon will not issue drivers to support the Windows 10 Operating System. The windows 7 or windows 8 drivers should function in the Windows 10 environment with some limitations that are currently unknown to Canon".
That was April 2020. Shame on Canon....they are trying to sell more new printers. Do not let them hold you back from upgrading to w10.
