Whenever I need to scan (or sometimes even to print) anything, I need to go into System Preferences, then Printers & Scanners, then click Open Scanner…
Isn’t there a one-click solution to do this ?
Yes there is.
Back in the days of MacOSX there used to be an option for this called “Desktop Printer” : that would put a shortcut-link of your printer on the Desktop. And you could do the same for your scanner.
Nowadays, for some reason, this option is gone, and no easy alternative is given by macOS… so you will have to create some thing yourself… the easiest way is to put both your Printer’s and your Scanner’s icon in the Dock. To do so, do this :
go to Apple menu (Apple-icon top-left in the top menu bar)
when the pulldown menu appears, select “System Preferences”
in the window that opens, click “Printers & Scanners”
if there is no such option, click on the raster-icon (top-center) first and it will appear
in the window that opens, click on your scanner (in the list on the left)
if your scanner is not yet in the list, add it first by clicking the Plus-icon at the bottom and following the on-screen instructions
now your scanner opens in the main part of the screen (on the right)
click the “Open scanner” button
now, the Scanner-window will open, and the scanner’s icon will appear in the Dock
CTRL-click (right mouse button) on the Scanner’s icon in the Dock
from the popup-menu, select “Options”, then “Keep in Dock”
now, the scanner’s icon will be moved to the left and it will stay in the Dock even after you close the scanner software
so, next time you want to scan anything, just click on the scanner’s icon in the Dock to open the scanner software
That’s it !
Note : creating a direct link icon in the Dock for your printer can be done in the same way
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 ?
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
The fact that it’s a Java-based app is not the real problem (as long as you have the latest version on Java installed on your Mac). The real problem is that since macOS 10.15 Catalina, macOS has very strict security and privacy settings (compared to any previous version of macOS, OSX or MacOSX).
