fixed : CanoScan 5600F driver for macOS Big_Sur

Question :

I have a Canon CanoScan 5600F scanner that worked great with my previous Mac, but now I have upgraded to a new Mac running macOS 11.0 Big_Sur.

I’ve looked on the Canon website and searched the internet, but there is no macOS 11.0 Big_Sur compatible driver available for this scanner.

Is there any way to use this CanoScan 5600F scanner in macOS 11.0 Big_Sur ?


Answer :

Yes, there is :

  • goto Canon’s US website :
  • choose Support > Scanners > Film & Negative Scanner > CanoScan 5600F
  • or use this link :
  • there, choose the “Drivers & Downloads” tab
  • then, choose “macOS Mojave v10.14” as your operating system and “English” as your language
  • then, choose the “Drivers” tab
  • now, you will see 2 drivers listed :
    • > 5600F Scanner Driver Ver.14.11.5h (Mac) : msd_-mac_cs5600f-14_11_5h-ea8_2.dmg
      • > ICA Driver Ver.4.1.4a (Mac) : misd-mac-ijscanner2-4_1_4-ea21_3.dmg
  • download both of them
    • note that despite the fact that both are versions from 2018, these will still work with macOS 11.0 Big_Sur
  • goto your downloads folder
  • first, double-click on the file named msd_-mac_cs5600f-14_11_5h-ea8_2.dmg
  • this will mount the ScanGear_CanoScan 5600F_141105.pkg
  • again, click on that and version 14.11 of the ScanGear driver installer will open
  • now, follow the on-screen directions and the latest ScanGear driver will be installed
  • then, double-click on the file named misd-mac-ijscanner2-4_1_4-ea21_3.dmg
  • this will mount the Canon IJScanner2_040104.pkg
  • again, click on that and version 4.1.4 the IJScanner2 driver installer will open
  • now, follow the on-screen directions and the latest IJScanner2 driver will be installed
  • when done, goto System Preferences > Printers & Scanners
  • if the CanoScan 5600F is already listed on the left, click it
  • if not, click the +sign (plus-sign) to add the scanner first
  • when done, click the CanoScan 5600F in the list on the left
  • when the scanner details open on the right, click on the “Open Scanner”-button
  • now, the built-in macOS scanner-app will open and it will immediately do a preview scan of whatever is in the scanner

NOTE : you might run into a small problem every once in a while ; when the automatic scanning preview starts, you might get an error saying “Scanner reported an error – Cannot communicate with scanner for these reasons: – Scanner is turned off. – USB cable is disconnected. Please check and try again.” If so, just flip the scanner’s ON/OFF-switch in OFF-position manually and then back into ON-posistie. That should help in making the scanner preview work again.

enjoy 😉



fixed : Canon scanner error -21345 on M1 Mac

Question :

I have have just upgraded to a new MacBook Air M1 2020 (with an Apple M1 processor) running macOS 11.0 Big_Sur. Now, I am trying to get my Canon PIXMA MG3250 All-in-one printer-scanner to work with it… but even though I can get the printer function to work, when I want it to scan I get an error…

Installing the Canon MG3250 through System Preferecens > Printers & Scanners > Add Printer was really simple as it was immediately seen through Bonjour. After installing, the MG3250’s icon is listed on the left, and when I click it, the window opens where I can choose either the “Print” or the “Scan” tab. After choosing the later, I get the “Open scanner”-button, and when I click that, the built-in macOS scanner-app opens the “Scanner” window… which gives this error : “Failed to open a connection to the device (-121345)” each time I try. I just can’t get it to work.

What is wrong ?

Answer :

When you get this error in this setup, you will probably have gotten an error saying “IJScanner3” also. Do this to fix it :

  • goto the Canon UK website :
  • there, browse to the PIXMA MG3250’s Driver Support-page or go there directly using this link :
    • Yes, that’s right, even though you are running macOS 11.0 Big_Sur and Canon tells you there is no driver for such an advanced OS, the macOS 10.15 Catalina driver still works
  • when you see the ICA Driver Ver. 4.0.0a (Mac) version listed, click the blue download button to download
  • in your downloads folder, you will now find a file called miss-mac-ijscanner3-4_0_0-ea19_2.dmg
  • click that file and it will mount an installer called Canon IJScanner3_040000.pkg
  • click that file and the 2020-version of the scanner driver will be installed
  • when done, make sure the System Preferences are closed
  • then open System Preferences > Printers & Scanners > MG3250 again and click the “Open Scanner”-button
  • now, the built-in scanner-app will open the Scanner-window again, but hits time without the error… so you are good to go !

That’s it !

enjoy 😉
