If you read all the responses to this problem in this thread, you will find that there are a few messy work arounds to get tyour scanner to work. I used the one with Preview, but unless you buy the full version you wind up with watermarks all over your scan. Buying the full version ($40) costs nearly as much as buying a new scanner. So what's the use of that solution. The problem isn't just with your model it is with dozens of older models. I have two different models that now won't work. I haven't read of problems with other major suppliers. So the message is DON'T BUY CANON again and be careful before you upgrade operating systems. Read the users forums and magazine articles to see what issues are being reported. The other problem is that it is hard to get such problems elevated to a forum with a large readership. This is buried so far down you don't find out until it's too late.
The problem seems to be that Canon wants everyone to go buy new multifunction printers rather than fix a problem that should be easy to resolve on their end. The problem is really a Canon problem and they clearly don't care that they are alienating so many existing customers. However, I also fault Apple for not letting people know that once they upgrade their peripherals may not work. They did this for many third party apps re IOS 11 letting people know that many apps might not work with the new system. I for one still haven't upgraded due to both this and the fact that all recent releases of IOS seem to cause more problems that the upgrade is worth. This can be evidenced by the fact that they have had to rush out over 7 updates in just a few weeks and each one fixes some problems and creates more. But they didn't do this for High Sierra. I haven't found anything in High Sierra that is worth the printer problems it has created.

I agree 100% with waltgoede regarding Apple and the lack of warnings in the High Sierra upgrade, and the nearly nonexistant changes in High Sierra to warrant the headaches outlined in this thread. I mentioned this a few pages back.
Meanwhile, there still is no excuse on Canon's part. There is no replacement printer tht they see that would be a user upgrade worth all the time invested in buying, setup,old printer sell or discard, etc.
Are you paying attention Canon??? This is NOT okay. High Sierra has been out for months, and we have heard nothing from Canon as to whether or not we will get relief here. Common sense says that an upgrade is something that can be delivered.
Common business practice and customer service dictates that there is an obligation on Canon's part to communicate at the very least.
Canon software writers: Are you waiting for this thread to get to 20 pages?? 30?? Contact Apple and work it out!

Thanks for the reply. Mine is a new computer that came with 10.13.2 preinstalled, the latest version of High Sierra. My printer, MP970, WAS capable of scaning 35mm photo negatives and slides and I do use it for that, as well as regular scaning. I really don't want to have to get another printer/scanner. I sounds like Canon doesn't care and is not going to upgrade MP Navigator. I have 3 Canon printers, but only the MP970 does 35mm negatives and slides. Guess Canon will NOT be my next purchase.

There is no solution.
Since OS (High) Sierra, there is no software like "MP navigator EX" supporting my Pixma MP640 available on your website.
If "My Image Garden" replaces "MP Navigator EX" I should be able to scan using this applicartion but I don't.
"My Image garden" is sloooow, even on my 2017-iMac. Probably because it's scanning my photolibrary. In fact this is not where I am waiting for. I need a fast application from within I can scan a pultiple PDF-document with the possibility of OCR.
For scanning Photo's I'm using Photoshop and the twain-module.

So I got my MX870 to work with MP Navigator 3.1.5 by doing the following:
Go to the canon support site and navigate to where you put in your printer model. It autodetects the version of OS you are running...mine detected High Sierra. But click the pull down menu there and select Mavericks. That will give you an option to download MP Navigator 3.1.5. Install that and make sure you run the new one it installed (from Launchpad). Worked just fine for me and scanned like it always has!
Not sure if this link will work, but this is the link to that download page I used:

Thank You, this works fine for me. A simple Google-search for version "MP Navigator X 3.1.5" gave me the following link: http://support-th.canon-asia.com/contents/TH/EN/0200328215.html
