Mac no longer works with scanner

This all seems to be related with a scanner application not being signed.

There have been others who have posted the following solution:

In the Finder, press Command-Shift-G and paste

/Library/Image Capture

Locate the application with the name of your scanner there.

CONTROL-Click and choose Open. Confirm.

Have you downloaded and installed the latest Epson Scanning driver for the WF 4725?

Its easily found on the Epson website in the Support printers section.

The UK download page is here:

https://www.epson.co.uk/support?productID=21257&os=38#drivers_and_manuals

The file name is epson636725eu.dmg

Date released 5 Oct 2020

version Epson Scan 2

The driver is a TWAIN driver and will work using Image Capture app on the Mac

Since your WF-4725 is now printing and scanning, I would not mess with success. However, this device is also supported by Apple’s built-in AirPrint when networked (not connected via USB cable) for both printing and scanning (Image Capture).

AirPrint operates independently of Epson drivers and scanning software. When one resets the printing system in Printers & Scanners panel, one chooses AirPrint for the device instead of Epson drivers.

Did you try scanning using Preview or Image Capture?

I have not installed any of the manufacturer's scanning software in over a decade.

Just

Preview File->Import from Epson ...

Hello Folks! I use a Xerox printer/scanner and ran into the exact problem, however I found a solution!

I had to enter the hard drive library, looked up Image Capture and located the printer driver. From there, right click on the driver, Get Info, at the bottom you’ll see sharing preferences and set everyone to Read and Write.

Also make sure you run the actual driver before running Image Capture. I think you need to run it everytime you want to scan so I just set it as a program to run everytime my Mac boots up. You can set this up in Users. Here’s a pic to clarify a few things:

I hope this helps everyone with this problem! Lmk if you need further explanation!

This was very helpful Luis! THANK YOU!!! I would just like to add that when I clicked "Open" nothing happened. I had to Get Info, UNLOCK it (in the lower right-hand corner) and then change the Privilege for Everyone from "Read Only" to "Read & Write". (And I'm not a specialist in ANYTHING, especially "Apple Watch"; not sure why this was assigned to my user... but will change it if I ever figure out how!)

Thanks for this tip. I was getting the same message reported by many (that I didn't have permission to use the scanner on my HP printer––the printer connection was fine and working), and this simple fix, which took about a minute to implement, did the trick. HP Easy Scan is now working on my new MI Mac desktop.

Here it is again, slightly edited:

In the Finder, press Command-Shift-G and paste

/Library/Image Capture/Devices

Locate the application with the name of your scanner there.

CONTROL-Click and choose Open. Confirm.

After that, scanning should work normally.

I was getting so frustrated because I was unable to scan some important documents. After messing around for a couple of hours I came across this post and I was finally able to scan my documents. Thank you so much for the help!

It’s not just Epson. My Canon flatbed scanner no longer works, and I’ve seen people online complaining about HP as well. Something about the 11.5 update has broken scanning for a LOT of people.

I did get my Canon scanner working again. This helped:

It should only be necessary to launch this driver separately once.
