Hello my name is***** look forward to assisting and am very sorry to hear that you are having this problem. Can you print ok? What happens when you try to scan?
.
Customer: replied 1 year ago.
print is good. got error when trying to scan:
Cannot communicate with scanner for these reasons: - Scanner is turned off. - (If using Wired LAN connection) It is disconnected from Wired LAN. - (If using wireless LAN connection) Signal strength is poor due to obstructions. - Network connection is prohibited by security software. - Different scanner on the network is selected. Check the above and try scanning again. If you still cannot communicate, restart the computer. Code:15,157,0

Expert:  Freddy M. replied 1 year ago.

I meant did you use preview, canon software, etc. Try this way for me.
Click the Apple menu, and then click System Preferences.
Click Print & Scan, or Printers & Scanners and then click your printer in the left pane.
Click the Scan tab, and then click Open Scanner.
If a 'Software for this device is not installed' message displays after you select your printer, click Install, and then follow the instructions to complete the installation.
Click Show Details to view scan settings and options.
note: Make sure that you select either the Flatbed mode or the Document Feeder mode, depending on your printer and how you plan to scan.
Change any settings as necessary, and then click Scan.

did that already... sofware is installed...
Expert:  Freddy M. replied 1 year ago.

That is not for installing the software, that is to start a scan from the Mac itself. Please ignore the install part of those steps but try those steps for me and tell me exactly what happens.

Customer: replied 1 year ago.
i have this message as soon as I thy to scan:
Cannot communicate with scanner for these reasons:
- Scanner is turned off.
- (If using Wired LAN connection) It is disconnected from Wired LAN.
- (If using wireless LAN connection) Signal strength is poor due to obstructions.
- Network connection is prohibited by security software.
- Different scanner on the network is selected.Please check and try again.

How did you install the printer? Do you know if it installed the TWAIN driver? What version of Mac os are you using?
.
Customer: replied 1 year ago.
on this iMac i am running the El Capitan Osx 10.11... it s a beta so i thought it could be a problem.. then tried with my macbook running Yosemite OSX 10.10.. same thing..
i don t know about the TWAIn drivers...
not sure what it is
Expert:  Freddy M. replied 1 year ago.
.
Ok please go to this page:
http://www.usa.canon.com/cusa/consumer/products/printers_multifunction/photo_all_in_one_inkjet_printers/pixma_mg7520#DriversAndSoftware
Scroll down and if it does not show it change it to OS X 10.10.
Then below that click on drivers to expand it, please try installing the ICA source as I think you may be using TWAIN.
Then test it again and let me know the results.
If this did not work, please come back and let me know what happened when you tried it by clicking on reply to expert so we can continue.
If it did work, please don’t forget to leave a positive rating - it is greatly appreciated.

Can you test it via usb to the mac with print & scan the way I sent you before? You may need to reset the print system for it to detect properly. If you get an error this way too please give me that error.

It scans properly with usb this way? If it does once again reset the print system but add it back again one more time wireless.
.
Customer: replied 1 year ago.
yes scan good with usb.reset all.. problem again with wireless
Expert:  Freddy M. replied 1 year ago.

Ok you may have a permissions issue. On the Dock, click Applications, and then click Utilities.
Double-click Disk Utility.
Highlight your hard drive/partition on the left (by default this is "Macintosh HD").
Click the Repair Disk Permissions button at the bottom of the window. Once the repair is complete, restart the computer and download and install the canon drivers from the site I sent you before.
Now when adding using the + choose either the Canon driver you installed or airprint.
