canon mg5520 can't connect to my MacBook pro no scan ability I can print just fine,  I can not scan from mg5520 


I've even tried to go through image garden and the "scan" area is greyed out. 
I’ve removed some software that I didn’t make note of 
I reloaded my Mac with all updated drivers


I can think of nothing else to try except throw this thing away. 

I has worked just fine for the last few years.
Canon doesn’t have drivers for that past 10.14 and full functionality is only specified for 10.4 through 10.6.

Unless someone with more experience has an answer, donating that to someone running a compatible OS would be my best use of that gear for scanning. Many canon scanners work with macOS Catalina due to updated drivers, so you could also wait for the vendor to work on your scanner or request support from them. I wouldn’t rule out a community driver if someone decides to take that task on and then releases a third party driver.
