Thanks, Mark. In the elegance stakes, that solution scores zero, I'm afraid! Fortunately, by updating MP Navigator to v4.0.5 and reinstalling the IJ Network Tool in its latest version, all problems with my MG 6150 have been overcome. Took me a couple of hours to sort that out and I would have hoped for an auto-update from Canon, to be honest, but the job's done, thankfully. Hopefully this might help other sufferers.
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.
Dear Canon, The only help that I got from your staff is a 20% off for a new printer (available only on you e-commerce). No words. Do you really think we are stupids? Do we have to give you more money for changing our devices just because you decided that we don't deserve the right drivers? Guys let's find [Mod Note: Removed links per forum guidelines]. what can be our next printer! see you! F
The MP Navigator software (at least on my MG6220 printer) is under the Software tab which is to the Right of the Drivers tab on the Drivers and Download page. I spoke with Tech support today (only on hold about 10 mins) and the gentleman was very helpful--walked me thru deleting the old scanner files (anything with MP in it) from the Canon utility folder; reboot; download the current Scanner Driver (the ICA driver is optional--may be what makes it work in Preview) and install; Under System Preferences/Printers and Scanners; right click on the Canon printer and "reset printing system"; (I forget if I rebooted after that); then add the Canon printer back in again (I don't remember if I downloaded the current printer driver--don't think I did because the printer modality was working OK); then go to the Software tab to the right of the Drivers tab and download the "MP Navigator EX Ver. 5.0.4 (Mac)" software and install it. I think re-booted again. And opened the MP Navigator (and put the icon in the dock); and it worked! I found the Canon tech support VERY helpful. He did say it took them a while to get this glitch figured out after Apple changed the OS.
In addition to my last post, I negelcted to add that I spoke to both Customer Support and Customer Relations at Apple.
They knew nothing of this problem, it's way off their radar.
That should say a lot. This is most likely a done deal. Time to move on.
