Canon has stopped supporting most older printers on computers that have been upgraded to High Sierra. If you look at the Canon website you will find my Canon printer owners saying that they can no longer scan in High Sierra as MP Navigator no longer works. Canon says Tough luck buy a new printer. So don't upgrade to High Sierra if you have an older Canon multifunction printer.
MacBook Pro (Retina, 15-inch, Late 2013), OS X Yosemite (10.10.2), Mail 8.2
Or upgrade and get a new, compatible printer because this is not Apple's problem. Apple doesn't make printer drivers.
If you can print then you might see about scanning with VueScan that supports many older Canon devices.
I agree that this is not Apples problem. The problem is with Canon. They have left tens of thousands of owners of still functioning Multi-Function printers with a printer that can no longer scan. This is a big problem for a lot of users and I for one will never buy another Canon printer. They are offering a pathetic 20% discount, which is less than you can get in most stores. Shame on you Canon!
The reason I posted this on the Apple forum is to let others know they have a decision to make:
1) Upgrade to High Sierra and get what I have seen are really minor practical improvements for most users and as a result of the upgrade you will have a multi function printer that is useless as a scanner or
2) Don't upgrade to High Sierra and have a printer that works
For me the choice is clear. I have both an iMac and a MacBook Pro. Unfortunately I already upgraded the iMac but haven't upgraded the MacBook. I do not intend to upgrade the MacBook as long as my Canon still works.
Thanks Kappy
VueScan worked fine. However the free version imbeds a watermark in every scan. It costs $40 to get a clean version for 1 year. As a new scanner from Canon can be had for under $50 I am not sure that it is worth getting the paid VueScan. I will live with the watermark for now. Fortunately I have a laptop that I won't upgrade to High Sierra that I can use if I need a clean scan.
Thanks for your help.
It would be helpful to others if Apple advertised more clearly that upgrading may create problems for peripherals so people can make this decision before they upgrade.
This is disgusting. I have a perfectly good Canon Printer/scanner that does not scan any more. Fault lies on both sides. Surely Apple should have warned us that we would no longer be able to use certain applications, before asking us to upgrade. Canon should work a fix. If I do have to purchase another scanner, it won't be canon. I certainly won't upgrade any more apple systems either. Short term view I think from both Mega companies
I agree. Products like Vuescan which you have to buy to get your scanner to work or other bandaids are poor work arounds. Shame on Canon and Apple needs to warn people that peripherals may not work after upgrades.
I have sorted this out now. Simply go to printers and Scanners in System Preferences in Apple Menu. Click on printer and scanner. Then hold control key down and click anywhere with mouse. Then choose reset. Once I did this mine opened. Hope that helps
Have you tried VueScan as I suggested?
Go to your Applications folder and open Image Capture.
