Scan from iPhone (MacOSX) Error : Device was disconnected

Hey there, gilleswlk!

Thanks for reaching out in Apple Support Communities! If we understand correctly, you're able to scan a document to your Mac, but when it tried importing the scanned item you receive an error.

It looks like your Mac might need to be updated. We recommend updating to the latest macOS version first, then check if the scan is imported properly.

Feel free to post an update for continued support.

Kind regards.

In my case, the problem disappeared after updating to Big Sur. Interesting.

I'm having the exactly same problem I think since the iOS14 update. Tough, I only have been scanning A5 sized notebooks and with those it keeps crashing after shooting the first scan, before offering next scan or "done". Error message: "the device was disconnected". The problem seems to be with continuity, since scanning to Notes does work as usually.

I have updated both my iPhone SE (2nd gen) and Macbook Air (2020) to the newest OS.

A workaround for me is to set the scan from Colour to Black & White. You can do that on the iphone/ipad just before you scan (strange icon below the flash). Unfortunately, you have to repeat it for every scan. Welcome back to the 80th.

Catalina 10.15.7 (Air Retina 12" 2016)

iOS 14.2 (Iphone 8)

Same problem with disconnecting after taked scan with iPhone.

Everything worked perfectly before updating iOS.

iPad seems to work fine at this moment.

Fix it please, its broke business-process for me.

The Problem persists in macOS Big Sur 11.0.1.

However, it is more likely an iPadOS 14.2 issue (including some earlier versions). Obviously, the scan app crashes for some larger documents. It is a shame that Apple is not fixing it. This is an important workflow!

I was able to make one scan from the iPad but it has failed since then. The iPhone didn't successfully do a scan. I rely on this workflow and it has consistently failed since the upgrade from iOS 13 to iOS 14 and I have had to use workarounds that add significantly to my workload. It is very disappointing that Apple has not addressed this.

Hi Dos, thanks for your suggestion. Unfortunately it didn't work for me. I installed update 14.2 today hoping that it would fix this workflow but sadly, it didn't.

The thing I have noticed is that it seems to depend on the size of the scan. If I am scanning a smaller document, it seems to work fine but when I scan an A4 page it crashes, every time. I'd be interested to know whether that's your experience as well.

Same here. Trying to scan in fuel tickets.

Please help!!! I’m having the same issue.

Update: I only managed to scan a few documents and now the same problem is back. Truly annoying...

I have exactly the same problem! Hope someone here has the solution

Thank you Dos! this solved the problem

MacBook Air Early 2015, Big Sur 11.01

iPhone 11, iOS 14.2

I have the exact same problem using both an iPhone7 (iOS 14.0.1) and an iPad Pro 9.7" (iPadOS 14.0) on my Mac (10.15.7). Right click on the Desktop and selecting Import from iPhone or iPad then Scan Document opens the camera on my device. The image is captured ok and processed to create a scanned document, however the process terminates at the point of sending the resultant image to my Mac. I had no problems scanning documents on iOS 13.7

I have noticed that the Continuity feature works when I take a photo from my device to my Mac and I can also scan on my device (phone and iPad) to the Notes app running on the device. This would suggest to me that the problem is specific to the document scanning using the Continuity feature.

Are others experiencing this problem as well? The Continuity document scanner is a really useful feature that I use frequently.
