Agree. Clicking on Manuals to download the manual from your link (TS3300 series (PDF) User Manual (Windows)) and then clicking on Applicable Models you will see OP's model TS3350.I think this means TS3350 is the base model
That's what I an up against at first, too. It happens with Firefox and Edge.At this moment of posting my link only opens a blank page.
You can use the installation disk or the drivers on the Canon site if they are newer. Do not upgrade the firmware unless there is something the newer fixes that is a problem for you (rare) or there is a new function that you absolutely must have (very rare).Advice on which to use most appreciated.
