I have a MG6850 multifunction Canon printer. Recently the Canon IJ Scan Utility has misfunctioned. I can scan the first page of a document without problem, but when I want to scan a second page of the same document by clicking on "Scan" in the small dialogue screen I receive the message "Failed to open a session on the device". I have re-downloaded and installed successfully the scanning software using mcpd-mac-mg6800-16_04_1_0 ea21_3.dmg installer software, but it has not resloved the problem.
I am using a MacBook Pro with Mac OS Catalina 10.15.3
Can anyone help me, please?

Pity you cannot help me. I google Canon Printer Forums and the only one that appears is this US one!! There does not seem to be a Canon forum in Europe, at least it is well hidden by Google. Why Google with its notorious algorithms throws US sites top of the list when I I am working in Luxembourg beats me!! Very frustrating.
I have written an email to the Canon Support site in Luxembourg (which I suppose is wider than Luxembourg in reality) but it has been less than helpful in the past. I generally find user forums much more useful than manufacturer's support sites in dealing with this sort of problem.
I see from lavato's reply that my problem is not unique to me. You may not have Pixma MG6850s in the States, but dio you have that error message when scanning with other models? I cannot imagine that the Canon IJ Scan Utility is exclusive to the MG6800 series.

Sorry, made a mistake in the reference to the scanner installer software: It should have been <misd-mac-ijsscanner 15f-4_1_3-ea21_3.dmg>

I am having the exact same problem. I live in the U.S. Will you please tell me how to fix this issue. I have tried everything the previous person did and keep the getting the same error message: "Failed to open a session on the device."

Are you on Catalina, too?
I am going to guess that it is a 32/64 bit issue. Have you tried scanning with Preview or Image Capture directly?
