Pixma MX922 and OS X Catalina

MattKauf — Sat, 16 May 2020 17:53:42 GMT

I've had my Multifunction for a while and am using with with the Canon scanning software on my Macbook Air running OS X Catalina 10.15.4.

Since the update to Catalina, I have noticed that if I scan a document, then change the settings for another document, when I click on the scan button, nothing happens. I have to quit the application and then scan. The changes to the settings were saved with the last running of the App, I just couldn't scan until I quit.

Any suggestions?

Thanks.

Greetings,

What we hear from a lot of MAC users:

Printer has been working fine / normally, then after one or more OS upgrades some functions start to become problematic, unreliable or deteriorate.

This is often due to the architectural differences between old / new versions of Mac OS and drivers. If you've been using MAC OS for a while, then you know how different Catalina is in comparison to Mojave.

What I would recommend:

Remove the printer from Apple menu > System Preferences > Printers and Scanners.

If no other printers are installed, then "Reset The Printing System" (Control+Right-Click)

Now uninstall all Canon related software, then restart.

Now reinstall the device using the Catalina CUPS and Scanner drivers:

This seems to help in the majority of cases where orphaned files and lingering remnants cause odd or undesired behaviors.

Nice to meet someone with more than 1900 times my experience on the "Boards."
