Mac OS Mojave Scanner Not Working

I have the same issue with my Samsung CLX-3185FW. It's only when I select Colour mode. Black and White and Text work fine. In colour mode I get an error message for all formats except PDF. For PDF, the document gets created but the PDF cannot be opened.

Having the same problem with just the same printer, I contacted Hewlett Packard (which now owns the Samsung printer section, unfortunately) support over here in Germany. They told me that I need to talk to Apple since it's their system that is no longer working. The only solution HP offers is using their own scanner software.

Resetting the print system does not help. The latest drivers they have are from 2017.

macOS 10.14.1 Mojave was released this morning after the hardware announcements. For those with printer issues try installing that update and see if your printer problems are any better. Not guaranteeing anything it’s worth a try.

I tried just now. Updated to official 10.14.1 (I'm coming form beta 5) and nothing is changed in relation to scan problem.
So We need at least to wait for 10.14.2, but seem that Apple would not fix this problem pointing the finger to manufacturer drivers problem.
I plan to return to High Sierra, due the only real news of Mojave is the Dark Mode the is not working fine too.

Same problem with my Samsung CLX-3185F, on macOS 10.14.1.

Image Capture scanning in color fails, but scanning in B&W works as already mentioned.

Same thing happens when scanning with Photoshop (seems to use the same scanner API/drive/Framework).

VueScan works fine (have a license since 2003 - one of the best software purchases I've made).

From the top of my 30 years as a software developer I dare to say that Apple changed/broke something in Mojave and HP is not going to make any effort to adapt/fix the drivers to it. Interesting though that other software works, that points more to a problem on the Apple side. Only hope is for Apple to acknowledge the problem and issue a fix.

My guess is that the drivers for Mojave are the same as those for High Sierra. Since it was working fine in 10.13, Apple can easily address the issue. As the fix will need to be on Framework side (not drivers), we will have to wait for an OS update.

Let's hope they will look into it!

I'll bet that the drivers for all the printers and scanners that stopped working are 32 bit drivers since Mac OS 10.14 does not support 32-bit drivers anymore. The solution is the scanner manufacturers need to write and release 64-bit drivers for these models. Unfortunately, many are unwilling to do that for older hardware. I had to replace my Canon LiDE 70 as Canon didn't write 64-bit drivers for it; I got an LiDE 220 (love the small form factor) as a replacement.

BTW, Vuescan comes in both 32-bit and 64-bit versions so if you buy/use it with Mojave, get the 64-bit version.

Wrong, if is a 32/64 bit driver problem, the scanner doesn't work at all, but unlikely in B/W work perfectly, but in the color mode all is messed up. Again IS NOT a driver problem, is an Apple problem and only Apple can fix it.

Also a third part scanning program like Vuescan or Samsung Easy Document Creator, uses the identical installed driver that doesn't work with with Apple Scan utility. The drivers are OK.

If Apple fix this little problem, all scanners return to work.

Actually Apple is not sensitive against this problem, and neither in the 10.14.2 beta this problem seem fixed.

I do not understand why it is the printer or scanner manufacturer’s responsibility to understand the OS udate. This happens everytime. There should be better collaboration. There are no surprises here. Very frustrating. My Neat scanner which is basically a fujitsu is again not working and no solution in sight. Crazy.

Because it is up to the peripheral manufacturer to make sure the software required to run their product works in Windows, MacOS, etc. Neither Apple nor Microsoft has the time or personnel to test (much less write) the software for thousands of different peripherals each year. Apple (I don't know if MS does) at least works to include the software written by the manufacturers into MacOS rather than requiring you to download it from them.

I have the same problem with a Canon Pixma MG6200.

When I click on Scan>Open Scanner>

I get a fault that reads: "Software for @ failed to run. (-9927)"

Very annoying. Is there a workaround rather than having to buy a new printer?

Or how do you change back to the old operating system?

I tried all the recommendations (restart print service, re-install print drivers, use a usb connection, try saving as pdf, try to use a different scanning utility) nothing works.

I was just about ready to go buy a stand-alone scanner, so I searched what works with Mojave and guess what - there are a ton with similar problems. But I did find a fix : someone recommended VueScan https://www.hamrick.com/

Yeah it costs $ but it worked for me(cheaper than new scanner). Still very irritated that Apple broke and doesn't seem the least concerned about fixing something that worked before the upgrade to Mojave - blame it on HP or whoever, the stuff worked before Apple came out with the upgrade.

Hallo.

Have got same experience. not possible to scan photo file extensions after update to mojave OS.

Find Apple respond to this problem to nothing.

Maybe apple consider this problem to be a fake user problem ?

Does Apple participate in this community ?

Hope so Scanner problem have been since update.

If someone in responsible position read this ... please take action A.S.A.P.

I have just spent 3 hours trying to sort this out - I use PDF Scanner and have not been able to use it since upgrading to Mojave - however this evening as a last ditch attempt I deleted and reinstalled the printer and scanner drivers for my Samsung M2070W and it worked faster than it used to - so I hope this solution will work for you too!!

Basically I want into system preferences clicked on printers then the minus sign to remove the printer and scanner then just pressed the add sign and the only drivers I was offered were for the Samsung printer added them and all working fine! Sounds too simple to be true it was that easy!

Hi everybody,

I had a similar problem with my Epson WF 2760 and searched the web finding that this seems to be a widespread OS X problem which seems to occur when IPv6 is activated in the printer settings.

Simple solution: Deactivate it!

This is very simple once you've found out where to change the network settings of your printer (NOT the Mac's and NOT the router's settings).

I'll describe what I did to fix my Epson:

My printer is connected to my network via WiFi, so I could access it through my browser:

- I checked the printer's IP address in my printer's network settings (my printer has a touchscreen where you can check the settings in the network status).

- Next, I accessed the IP address via my browser (Safari) - just use it as an URL.

- In the Browser, an Epson Service Center came up with a tiny little Pop-up menu on the top right which at this point said "Basic Settings" ("Grundeinstellungen" in German). Pop it up and choose "Extended Settings" ("Erweiterte Einstellungen" in German) and you get to the actual Settings with a menu on the left.

- In that Menu, I opened > Network Settings > Basic

- Then I set the DNS Settings to AUTO and DEACTIVATED IPv6 and clicked NEXT.

That's it. Scanner worked even without a restart.

Hope this might help. Good luck!
