fixed : Canon scanner “Cannot communicate with scanner” error in macOS 10.15 Catalina

Posted on by

Question :

I have been using my Canon CanoScan 5600F scanner for many years with my Mac, and it has always been working great. However : now, in macOS 10.15 Catalina I keep getting error messages that the scanner cannot be found…

The exact error message is this : “Scanner reported an error Cannot communicate with scanner for these reasons: – Scanner is turned off. – USB cable is disconnected. Please check and try again.”

Sometimes I manage to get things working by replugging the USB-cable and switching the scanner OFF and back ON, but that solution doesn’t last…

What can I do to solve this ?

 

Answer :

even though Canon does not list support for your the CanoScan 5600F for macOS 10.15 Catalina, the Canon driver that used to work in MacOSX 10.7 Lion through macOS 10.14 Mojave still works in macOS 10.15 Catalina, so if you do not have this driver already, download it here

NOTE : this solution is tested to work for the Canon CanoScan 5600F scanner, but will probably work as well for other CanoScan and LiDE scanners that run into the same problem and error message

To solve your problem, do this :

  • go to Apple-icon (top left in the menu bar) and click on “System Preferences” from the pulldown menu
  • in the “System Preferences” window, click on “Printers & Scanners”
  • in the list on the left, at “Scanners”, select your CanoScan scanner
  • then, click on the Minus-button at the bottom of the list on the left, to delete the scanner from the list
  • now, switch OFF your scanner and unplug the USB-cable from the scanner and from your Mac
  • then, go to Apple-icon (top left in the menu bar) and click on “Restart…” from the pulldown menu
  • when prompted, UNcheck the option to reopen all open windows and restart your Mac
  • then, plug the USB-cable back into your scanner and your Mac and switch your scanner back ON
  • when your Mac has restarted, open System Preferences
  • in the “System Preferences” window, click on “Printers & Scanners”
  • in the list on the left, at the bottom, click on the Plus-button
  • in the window that opens, select your CanoScan scanner from the list and click the “Add”-button
  • you can now select your CanoScan scanner from the list on the left and click on the “Open Scanner” button on the right to open it
  • now, the “Scanner” window will open and you will be able to scan

You could be okay now, but you still might encounter this ‘Cannot communicate with scanner’ error again… in that case, do this :

  • click the OK button in the pulldown window that reports the error
  • then, option-click (right-click) on the scanner icon in the Dock
  • if your Scanner icon is not always visible in the Dock, do this first :
    • in the popup-list, select “Options”
    • in the next popup-list, make sure that there is a checkmark at “Keep in Dock”
  • now, close the Scanner window by clicking on the red button top left
  • then, reopen the Scanner window (by clicking on the scanner icon in the Dock)
  • now, the Overview Scan (preview scan) will start automatically as expected
  • if not, just repeat this process a little slower than you did before 😉

Note 1 : it seems like this problem is caused by macOS 10.15 Catalina cutting off all USB-connected devices when it puts your Mac in sleep mode (at the moment of writing there seems to be no simple way to adjust this in macOS…)

Note 2 : if you cannot live with getting this error once in a while, and you cannot wait for Apple and/or Canon to come up with a definite solution… have a look at the VueScan scanner-app

That’s it !

enjoy 😉

fixed : use unsupported scanner in OSX 10.11 El_Capitan

Posted on by

Question :

I have a Canon CanoScan LiDE 20 that used to work perfectly in MacOSX 10.6 Snow Leopard. But now I’ve bought a new Mac which runs OSX 10.11 El_Capitan, I can’t seem to install it, since Canon doesn’t update the drivers anymore.

What can I do ?

Answer :

In OSX 10.7 Lion, 10.8 Mountain Lion, 10.9 Mavericks, 10.10 Yosemite and 10.11 El_Capitan, any TWAIN-supporting scanner can be used without any additional software.

A list of supported scanners for OSX 10.9 Mavericks can be found here.

Here’s a quick step-by-step instruction :

– connect your scanner directly to your Mac using a USB-cable

– open the System Preferences

– then click on “Print & Scan”

– then, just below in the list of printers on the left, click on the “+”-sign

– that will bring up the “Add”-window, which enables you to add a new printer or scanner

– if your scanner is TWAIN-supporting, it will show up there, and you just need to select it and click on the “Add”-button

– then it will be listed in the previous (“Print & Scan”) System Preferences window, and if you select it (and you put a piece of paper or a photo in the scanner), a Scanning Preview window will show up, allowing you to scan your document to file or eMail or something else…

but…

…for some printers, like the Canon CanoScan LiDE 20 and LiDE 30, the TWAIN-drivers are not included in OSX. In that case, you will need to install some generic (FREE) TWAIN-drivers :

IMPORTANT : do not forget to read this entire post, even all the notes at the bottom ! e.g. if you have an old CanoScan scanner, you might have to reinstall TWAINbridge.app also !

– for OSX 10.11 El_Capitan, download and install these files (in this same order) and restart you Mac after doing so, then your scanner will also show up in the “Print & Scan” System Preferences :

LibUSB for OSX 10.11

SANE Backends for OSX 10.11

SANE Preference Pane for OSX 10.11

TWAIN SANE Interface for OSX 10.11

– for OSX 10.10 Yosemite, download and install these files (in this same order) and restart you Mac after doing so, then your scanner will also show up in the “Print & Scan” System Preferences :

libusb.pkg.tar.gz

sane-backends.pkg.tar.gz

SANE-Preference-Pane.pkg.tar.gz

TWAIN-SANE-Interface.pkg.tar.gz

– for OSX 10.9 Mavericks, download and install these files (in this same order) and restart your Mac after doing so, then your scanner will also show up in the “Print & Scan” System Preferences :

libusb.pkg.tar.gz

sane-backends.pkg.tar.gz

SANE-Preference-Pane.pkg.tar.gz

TWAIN-SANE-Interface.pkg.tar.gz

– for OSX 10.8 Mountain Lion, download and install these files (in this same order) and restart your Mac after doing so, then your scanner will also show up in the “Print & Scan” System Preferences :

libusb.pkg.tar.gz

sane-backends.pkg.tar.gz

SANE-Preference-Pane.pkg.tar.gz

TWAIN-SANE-Interface.pkg.tar.gz

– for MacOSX 10.7 Lion, download and install these files (in this same order) and restart your Mac after doing so, then your scanner will also show up in the “Print & Scan” System Preferences :

libusb.pkg.tar.gz

sane-backends.pkg.tar.gz

SANE-Preference-Pane.pkg.tar.gz

TWAIN-SANE-Interface.pkg.tar.gz

– if these files do not turn into regular .pkg-files when you click on them, you need unTAR-software like this :

The Unarchiver

– if you get an error-message telling you you can’t install this software (these drivers) since the are not from Apple-appoved developers, you need to :

– open the System Preferences

– then click on “Security & Privacy”

– then make sure the “General”-tab is selected

– click the padlock in the lower left corner and provide an Administrator name & password to unlock the padlock

– then at “Allow applications downloaded from:” select “Anywhere”

– and exit the System Preferences to make this setting stick

Note #1 :

TWAIN-supporting drivers (like SANE and the ones that come with OSX) will enable you to directly scan from within various applications like Photoshop, MS Word, GraphicConverter, OmniPage and OSX’s built-in Image Capture. [ please also read Note #7 and #8 for more tips on this ! ]

Alex Scheider has written a special SANE scanner app for OSX 10.7 and newer, you can download it here. A screenshot can be found here. [haven’t tested it, so feedback on this is welcome]

Note #2 :

when using the SANE drivers, you will probably not be able to use the ‘one click’-buttons that are on the scanner itself…

Note #3 :

if your scanner lets you scan the first time, but after shut-down and restart scanning seems impossible because OSX can’t find the scanner, just plug-out the scanner’s USB-cable and plug it back in and everything should work again…

Note #4 :

if the “Scan”-button remains grayed-out, make sure that you have selected an area to scan… (put differently : if “Selection:” is set to “Off”, you will need to select an area to scan before the “Scan”-button will be ready to use…)

Note #5 :

if you get a distorted scan when scanning in landscape view (or any other rotated view), just scan normally in portrait view and rotate the scanned image afterwards (in Preview app or another image editing program, like Photoshop or Graphic Converter)

Note #6 :

if you are not able to scan as a JPEG (.jpg-flie), just scan as a TIFF (.tif-file) and convert the scanned image afterwards (in Preview app or another image editing program, like Photoshop or Graphic Converter)

Note #7 :

if your scanner doesn’t show up in Image Capture (especially in OSX 10.9 Mavericks), use this workaround :

go to System Prefecences –> Printers & Scanners –> [your scanner] –> Scan –> Open Scanner

Note #8 :

if your scanner doesn’t show up in Photoshop (especially in OSX 10.9 Mavericks), try this workaround :

go to Applications –> Adobe Photoshop CS# –> Adobe Photoshop CS# –> type “CMD” + “i” key-combo (on your keyboard) –> (in the Get Info window) select “Open in 32 bit mode” and exit Get Info

then open Adobe Photoshop (CS#-version) –> File –> Import –> SANE

Note #9 :

another option that might just work to get SANE drivers to connect with ImageCapture and Photoshop (especially if you have an older CANON scanner) is (re)installing the TWAINbrigde.app that Jan Egil has ready for download on his website.

for now, there is no version of TWAINbridge.app that runs in OSX 10.11 El_Capitan, the alternative seems to be to use the old CanoScan Toolbox 5.0 software that can be found on the Canon website or here

tip : which scanners are compatible with OSX 10.9 Mavericks ?

Posted on by
8

Question :

Which scanners will work with OSX 10.9 Mavericks ?

Answer :

Just like with previous versions of MacOSX, the built-in compatibility with older scanners is rather low…

…in the specs of OSX 10.9 Mavericks there isn’t any indication of extended scanner support, so it is expected that “wireless scanning” (over WiFi/AirPort) isn’t supported either, just as was the case (or should I say “problem”) in previous versions of MacOSX…

Apple hasn’t published a list of pre-installed scanner-drivers either, so there’s nothing official on this…

…there is however, a (very short) list of supported scanners pre-installed in OSX 10.9 Mavericks itself :

CanoScan 5600F             find it in the US, UK or Germany
CanoScan 9000F             find it in the US, UK or Germany
CanoScan LiDE 100         find it in the US or Germany
CanoScan LiDE 110         find it in the US, UK or Germany
CanoScan LiDE 200         find it in the US, UK or Germany
CanoScan LiDE 210         find it in the US, UK or Germany
CanoScan LiDE 700F       find it in the US, UK or Germany

This list can be found in :

/Library/Printers/Canon/IJScanner/Resources/CIJIcons

…strangely, there are no such icons installed for scanners from other brands like EPSON and HP… so support for those scanners is either not included (yet) or left up to the individual manufacturers…

NOTE #1 : in MacOSX 10.7 Lion, OSX 10.8 Mountain Lion and OSX 10.9 Mavericks scanner-compatibilty can be extended by installing the SANE-scannerdrivers, as outlined here.

NOTE #2 : if you are a professional and/or heavy user, you could also try using the SilverFast 8 scanner-suite, which adds support for these scanners to OSX 10.9 Mavericks (since even the cheapest version, SilverFast SE 8, will cost you €50, this only is a relevant solution for professional and/or heavy users…)
