fixed : “Scanner reported an error” when starting scanner

Question :

My Canon CanoScan 5600F is scanning great, even after all those years. The only problem I’m encountering with my new Mac is that I get a “Scanner reported an error” message when I try to start it from the shortlink (alias) I have in my Dock.

The exact error message is : “Scanner reported an error Cannot communicate with scanner for these reasons: – Scanner is turned off. – USB cable is disconnected. Please check and try again.” But the USB cable is connected properly and the scanner is turned on, so that can’t be the problem.

What can I do to fix this ?

Answer :

This problem was introduced some years ago, possibly somewhere within the shift from OSX to macOS. It seems to have to to with the start-up sequence of macOS’s build-in scanning software or the scanner going into some sleep mode. The solution is simple, even though it is more of a workaround than an actual fix. So if you run into this problem, do this :

  • turn the scanner off using the ON/OFF-switch on the outside of the scanner (the physical hardware button)
  • then, click the blue OK-button in the “Scanner reported an error” window
  • then, close the “Scanner” window by clicking the red dot button top-left
  • then, open the Scanner software again…
  • now, turn the scanner back on using the ON/OFF-switch on the outside of the scanner (the physical hardware button)
  • now the scanner should load the scan preview automatically (as if you had clicked the Overview-button)
  • just make sure the scan area hasn’t been reset, so…
    • …either uncheck “Use Custom Size” and make sure “size” is “A4” (or anything suitable)
    • …or manually line out the scan area in the preview

That’s it !

fixed : remove icon from behind the Dock

Question :

I somehow managed to move an icon to the outer corner of the Desktop in such a way that there’s no way to select it and move it to another location (or trash it). The document icon even got placed behind the Dock, so whenever I try to select the icon, the Dock is in front of it, and I am selecting or activating something in the Dock…

How can I fix this ?

 

Answer :

If there’s a document icon (or app icon) on your Desktop that you can’t select to use or move the document (or app), try this :

– open the Finder

– in the Finder window that opens, select your Desktop, then select the file (or app)

– now move it to another location on your Mac ; to another folder or to a new folder

– then, when you go back to your Desktop, the file will be in folder you’ve just put it in

…and if you wish, you can even drag & drop it back onto any location on the Desktop.

That’s it !

Enjoy !
