Mac OS Mojave Scanner Not Working

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.

…and why can't Apple make a version of this software to make us all happy.

They do. It's called Image Capture. I doubt it will make everyone happy, though. It's a very basic scanning engine. Not all scanners work with it, though. The manufacturer must make the scanner compatible.

Hello,

I have exactly the same issue as described by ahvlima:

"Hi all!

I'm glad to say that macOS 10.4.4 seem to (partially) fix the problems, at least for my Samsung CLX-3815FW.

I say partially because now I can scan in color and save to almost all formats. The only format still with problems is PDF.

Savings as JPEG, JPEG200, GIF, TIFF, BMP and PNG works now.

When saving as PDF, if not "combining" (putting all scanned pages in the same PDF file), the produced PDF is not readable. If "combining", Image Capture just crashes!!!

..."

In my case with my Samsung SCX-3405W. Printer connected via WiFi (2,4 GHz), installed via bonjour, fixed IP.

IPv6 address disabled in printer settings. Running Mojave 10.14.4.

As of the 10.14.4 update, Mojave appears to support my Samsung C460 with color scanning. This works both via Image Capture and PDFScanner -- I'm relieved that Apple was able to fix this and hope it doesn't crop up again.

Thank you for your post. I have a Samsung C460 and when Majove was released in 2018. It would not scan on the printer. I went back to OS High Sierra and all worked again. Have you tried scanning many pages “combined” into a PDF document. Does this work?

Samsung M2070FW will work when switched to "Kind: Black & White"

Same here, nothing works except for using Samsung Easy Document Creator...

For me too: scanning in color gives the error. Black & White doesn't.

Strange. Maybe something to do with color management / color profiles.

Since installing Mojave, my Samsung SCX-4600 won't scan in "Color" mode. I'm getting "Scanner reported an error. An error occurred during scanning". Scanning in "Text" and "Black & White" modes are working normally. Scanning in color mode will produce a PDF when "Format" is set to "PDF" but the PDF file thus produced is unreadable by Preview or Adobe Acrobat.

same here, Samsung CLX-3175N

worked perfectly on High Sierra 10.13.6 and still works perfectly with my iMac 27" Mid2011.

Guess that's the only good thing about "not being able to upgrade the iMac to Mojave" :-)

On Mojave I can print, open the scanner dialog and also do the "Overview" scan (BW and Color)

Any attempt to SCAN the page will result in an ErrorMessage or a broken PDF.

On Top of all that I just figured that Samsung does not Support their printers anymore, ...

Also not really helpful :-/

Confirm the same with Samsung M2070W after the moving to Mojave - can scan only in b/w or text mode (In Sierra it worked fine).

I was trying some stuff to fix it, like reinstall printers, use the Samsung app, upgrade printer's firmware, repair permissions for the Home folder - still no result.

So have you tried resetting the printing system as recommended? Or do you just want to rant without accomplishing anything? Have you checked with Samsung’s printer support to see if there are updated drivers? What abut this do you not understand?

I just contacted Apple Care, I shared my screen with them to solve the problem.

They told me that should be a driver incompatibility caused by Samsung/HP so I have to contact them to release an update.

At this point I don't understand a couple of things:

maybe it is the truth if I add the printer using driver 2070 series from the menu, but if I use AirPrint why is a Samsung problem? As I know AirPrint is a technology driverless... Anyways it doesn't work.

So, is there anyone that know how to contact Samsung/HP to investigate the issue?

If anyone have something to tell to Apple, reply me and I will call them using my Apple Care 🙂

Apple doesn't participate in this community, it is a users' forum.

You can send them feedback:

Feedback - macOS - Apple

but they likely already know about this based on the number of posts. Do any of the workarounds help?

Thanks for sharing your solution. Unfortunately it does not work for me (I checked and as I expected IPV6 is off on my printer - I turn IPV6 off on every device that supports it) and I bet it will not work for others too. IPV6 being on or off does not change the fact that the scanner component fail under most of the usage (works for the preview for example). And it works fine with other software such as Vuescan, that rely on the drivers. The problem seem to be on the Apple side.
