Many people using Epson face this nuisance which of course can be solved using proper methods.

First start with restarting the computer. If it’s a minor error this will solve your problem.


If this doesn’t work for you; download the EPSON Scan Uninstaller from the Epson website. Then run it and re-install the software. This might solve your problem


If the problem is still there, uninstall the program again. Then reinstall it from the company website. Next you have to download

then copy “libraries/TWAIN source manager.shlb” out of the disk image, TWAIN for Mac OS XSDK.dmg.bin to “MacintoshHDsystemlibraryCFMSuppport”.

If there’s any existing file overwrite it. This should solve your problem

The workaround to that issue will be to uninstall any Epson Scan software that you have installed on your computer, and thereafter you will need to uninstall it, but the make sure that you do the reinstallation using the latest available version.

You may need to take note that you may experience issues while using EPSON Scan in case you have installed more than one version of its software application on your computer, and therefore you will need to check your system if there is such a situation and rectify it. if you have more than one Epson scanning product on your system, for instance, at least one All-In-One and one scanner then you will need to get rid of one and use one that is relevant.

That shouldn’t happen when using a scanner whether you are using an administrator account or a non-admin account. Every user on the computer can freely use the scanner and the software. If you keep getting this error every time you use the scanner, try to uninstall and reinstall the driver. Download the free version of Revo Uninstaller and install it.

Once installed, start Revo Uninstaller then select your Epson software among the applications and click “Uninstall”. Follow the normal uninstall process. When uninstall is complete, click “Scan” to scan your computer for any leftover files and delete everything it finds. This removes everything the program created on your computer. When it is finished, close Revo Uninstaller then install the Epson driver back.

See if this works. Try also updating the driver. Go to Epson Scanner Support. Here, enter your scanner’s product name like for example without quotes “PowerLite S27”, “WF-7620”, “ET-2500”, and others to search. You can find it printed on top, on the side, or bottom of the device. When your product is located, click it to go to the download page.

Download and install all available driver and software for your machine.
