Mac OS Mojave Scanner Not Working

Finally found the answer. You have to open the Image Capture app that was integrated into the OS. Your scanner is now working with this. I think Apple should email a list of all the changes before we download an app that changes things so much. I was so frustrated.

i had the same problem try using a usb cord i did and it worked for me hope it helps.

Download and try the demo version of VueScan to see if it will let your scanner work as intended.

Confirmed here: the scan modes 'Text' and 'Monochrome Image' are working fine, saving the output as any file format (JPEG, PDF...)

It's only the 'Color Image' that's buggy and won't output any file.

I had to add Printer again by hand, then the SCANNER TAB showed up on the second "the same" multifunction printer hahaha ;-)

For me, using the Samsung Scan Assistant works. It's only the mac internal scan system that doesn't.

I bought VueScan and everything works now...

These posters don't want to hear the truth, Ikrupp, their minds are made up!

I went to the HP site for Samsung drivers but HP doesn't list MacOS 10.14 (Mojave) as a supported OS for the Samsung products I entered. According to HP, if an OS is NOT listed, then HP does NOT have drivers that will work under it. Now, since Apple doesn't write the drivers for third-party hardware, they have to wait until HP provides them to Apple. Of course, HP would rather the Samsung users buy a new HP scanner product, so HP probably will take awhile to release Mojave drivers for old Samsung products. Perhaps if these posters were to compare the price of a new HP replacement to the price of VueScan they could make an informed choice. Unfortunately, there isn't a Unix scanning system like the CUPS printing one, AFAIK.

I have the same issue as well. Scanning worked properly for years, and today I faced the very same. The preview is working properly but for some reason it can't save the scanned image.

I tried resetting the printing system and all with no luck.

What worked for me is that I switched from Colour to Black & White and it works since. Now in most of the cases it's fine, but of course I'd like to be able to scan in colour mode as well

Have you checked with your printer’s manufacturer for updated drivers? Have you tried any of the suggestions here in this thread? What are you expecting from us here?

I am just curious- did you try to disable the IPv6 address in the printer? This really solved the whole issue for me and I can choose whatever way I like to scan: Image capture, preview or directly in the printers and scanner box. No need to buy something else.

I do have a temporary work around, set the color to monochrome. At least it is kinda working...

I can confirm that Samsung Easy Document Creator (v. 1.00.26) scans without any issues.

So, I agree, that the scan problem is a problem on Apples side. The "Easy Document Creator" works fine for Samsung scanners. I loved Apples solution via Preview though - hope they'll fix it

I have the same issue. Using the top scanner it works, if you use the glass directly it doesnt.

I maybe was not clear in my earlier reply: disabling the IPv6 in the printer settings ( so on the printer itself) solved the problem for me with pixma TS9550
