EPSON Scan software being put to sleep?

I have the latest EPSON Scan software (3.9.4.0EN) which according to Epson is tested for El Capitan. It has always acted a little weird – failing to notice clicks sometimes unless I Cmd-Tab to the app first, for example – but under El Capitan it is exhibiting some very annoying behaviour.

I run the preview scan and select multiple frames for full scan (I'm doing 35mm negatives) and it proceeds to scan the first frame. Then, sometimes, it pauses after saving that frame. To get it going again I usually have to click on its progress window (anywhere) and it will instantly begin scanning the next frame. One time the pointer was already over the window and I just moved the mouse slightly and that woke it up after a pause of several minutes.

At one point I quit it and relaunched and it could not see the scanner at all. A power cycle on the scanner did nothing and in the end the only thing that got it to work was launching VueScan and doing a test scan before quitting that and trying EPSON Scan again.

I could put up with most of the oddities but I often leave it to scan 6 frames which takes around 10 minutes only now I will have to stay with it to keep prompting it onto each frame.

The scanner is connected to an OWC Thunderbolt 2 hub and both VueScan and Image Capture can see it first time every time.

Is this some power saving feature causing the software to sleep while it's "not in use" (i.e. not getting user input)?

I got a call from Epson today and was told that Apple have changed the way USB is handled under El Capitan and that they will be including a fix in 10.11.2.

Meanwhile I'm getting various other instabilities. Sigh.

Ok, thanks for your update. Thats actually very good news, because I think Apple will release an update for El Capitan soon since there are some other major issues. At least we will not have to wait for Epson until the end of this year. 😉 In the meanwhile... I just keep clicking...... 😕

I have the same issue. Any news when the new patch can be expected from Apple or Epson?

Apple has just released an update for El Capitan (10.11.1). I have tested if the issue has been resolved by this update, but unfortunately that is not the case. The scanner still stops after each scanned negative in a batch scan. 😐

I received an update from Epson Australia a few days ago.

Our engineers are developing a fix for this issue which should be available in the next couple of months.

The updated Epson Scan will be available using the Epson Software Updater program or from our website.

In the meantime you will have to use the countermeasure of moving the mouse to get the scan to start/continue.

Sounds like a plan.

I have the same problem where Epson Scan stops between multiple negative scans

Epson V550

Elcapitan 10.11.1

To get it to proceed to the next scan I usually have to click on the progress dialog or click on Epson Scan in the dock, either one works

Hi,

Just purchased the V600 and immediately ran into this issue.. I'm on a MBP running El Capitan etc..

I installed one of those simple mouse clicker programs and early tests seem to suggest this does the trick. I got the "Mouse Clicker" off of the App Store. (Unfortunately it cost a bit, but I was in no mood to look further..). Basically lets you set how often and how many times the mouse button should be clicked each "turn". I set mine to once every 10 seconds.

I think this only works if I have the EPSON Scan app open, with the mouse pointer inside the app window though..so this might not be the ticket for everyone.

Still have issues if I am doing something else on the MBP, then I have to "jump" back to the Scan app to kick it back to life again.

Annoying..but perhaps this is a work around for some.

Let me just say I have no affiliation with the software I mention, it is the one I tried and it works for me.

I installed 10.11.2 this morning and the problem persists, so the rumour from Epson of something from Apple appears to hold no water. Still awaiting the Epson fix.

This is absolutely killing me right now. I just bought this scanner specifically to scan in about 2,000 slides before Christmas for a big family gift. I have to click on the EPSON Scan application and wiggle my curser around for Every Single Slide. Help! I'm guessing I need to be posting this in an Epson message board vs. this one, but these thread here was the only page on the internet that had information about this problem. Thanks for helping me out.

PS. While typing this, I had to click on the EPSON Scan application and move around my curser four separate times. I've got a long, miserable few weeks in my future.

Thanks for the Command-Tab trick!

Well, Epson has delivered a patch:

(Don't know why the link doesn't work, but see below...)

It can be found unter "Utilities" in den Download-Section for the V500... by now I have installed it, but not tried it out...

This does indeed appear to solve the problem! Woo!

I see what you mean about the link not working. It highlights on the page here but doesn't activate when clicked. Conversely, when I went to the downloads section for either the V500 or my V370 I could not see the download, but then I was looking at the New Zealand site. What I did manage was to copy the link off the page here and post it into the address bar and I got the DMG file from a page that states "Epson America, Inc" in the title.

In any case, I ran some scans last night and it was definitely pausing on every frame, but after installing this package it is now advancing itself whether Epson Scan is the current app or not and whether I touch the mouse or not!

I have downloaded it straight from the US-Page, mainly because the german site is a little bit crappy... :-) The update itself is a bit hard to find, cause Epson postet it under "Utilities" with such a random name as "Common Update" ... but: it works! :-)

The name of that file does not exactly explain what its for... I would not have found that by myself, so thanks for the hint!
