#504 Only one scan possible (canoscan 4400F)

[dmsuser]

Hi,
I thought I'd update naps2 and ran into a problem with the betas regarding (just) my canoscan 4400F. I can only scan once. After that the twain window of the scanner won't open. Same thing when I create or edit a profile. The canoscan is only listed in the twain device list for the first time round. Only after I close and reopen naps2 will it (temporarily) reappear in the list.

I run windows 10 and my flatbed scanner is as mentioned a canoscan 4400F. There is no windows 10 driver, just 8.1 but this works fine with all my programs and also with naps2 v 5.8.2.

Thanks for your effort. A really nice program.

Sorry Ben, for the late response. There is no errorlog. Definitely and nowhere. I searched with "everything" from voidtools. This is no reason for a missing errorlog but I should have pointed out that I use the portable build.

* Yes, closing+reopening consistently and instantly fixes the issue (for exactly one scan)
* No, waiting does not help.

Thank you for looking into this. It's strange, isn't it? For flatbed scans I use v 5.8.2 and drag n' drop into 6.X.

Hi Ben,

Nothing changes. There were two processes which I deleted. (But sometimes
there is only one.). And there is definitely no errorlog.txt. The search
program"Everything" would show it to me.

Best regards,
Rudy

PS
Sorry for the delay. I had read your mail, postponed my answer and then
forgot it altogether.

Hi,

Sorry I've been slow to address this. One more thing I'd appreciate you
trying:

1. Open NAPS2
2. Choose the device so that it stops being listed.
3. Open Task Manager (Ctrl+Shift+Esc). Click the arrow besides NAPS2
   to open the list. Right click and select End Task on the NAPS2 entries
   without the usual NAPS2 icon.
4. Try scanning/choosing device again.

Does it start to work again? Also, how many tasks did you end?

Windows 10 Pro 64-Bit
2x Intel XEON E5520

BTW in Beta4 I can create the profile but when I scan I get "Can't find
device" (or sth like that in german) immediately.

Best regards and in case it's the last mail before Christmas: Seasons
greetings, have a nice holiday
