Scan from iPhone (MacOSX) Error : Device was disconnected

hi there MoonJ, thanks for your response but that is not what was described. The issue has nothing to do with “scanning a document to your Mac” and is related to Continuity. The phone (and iPad) can scan a document and I can scan on my Mac using a TWAIN compliant flatbed scanner. The problem arises only when using Continuity.

I find it irritating that your answer is that “your Mac might need updating “ as I stated above that my MacBook Pro is running the latest version of Catalina (10.15.7) and the iss has only occurred with the update to iOS/iPadOS 14. I believe that this is a bug with the new mobile operating systems, possibly affecting only older hardware, and needs to be reported to Apple.

kind regards,

Joe

Hey gilleswlk,

thats a really interesting observation. Until now I had only tried A4 sized documents but at your suggestion I tried something smaller and I was able to scan an A5 sized postcard and a notebook of non standard size. I have tried scanning documents in Manual mode and dragging the constraints to a smaller size but this doesn’t work either.

Also, I realised that I had not been entirely accurate in my description of the issue. I said that the problem arose when transferring the data to the host Mac but after trying it a couple of times successfully with smaller documents, it definitely crashes at the point of processing the image because I don’t get the option to scan another image.

I have had this problem too and found that by turning off handoff on my mac and turning it back on again I am able to scan to the desktop again.

Click on  > System Preferences > General.

Scroll down and turn off. Allow Handoff between this Mac and Connected iCloud devices. Then turn back on again.

Fingers crossed this stays working!

Hi joecoleman, unfortunately this was a temporary fix and lasted for a few scans before I had to do it again.

I have found that even small fuel tickets that I need to enter on my accounting software don't scan, I usually scan larger (A4) through my printer. I haven't taken the plunge to install Big Sur yet, but it seems that that doesn't make a difference either.

This definitely needs a fix and soon.
