we use ImageEn 5.0.5 to scan via TWAIN. In the past our customers use the Fujitsu 6130 which works without problems.
Fujitsu discontinued the 6130 and replace it with the 7160 which delivers the PaperStream IP-Software for scanning.
When we start the scan in our app the app closes without any message after scanning the first page - no access violation, no error, nothing, just close.
Please report any issues you have to our technical support department at 800 626-4686 or email tsupport@us.fujitsu.com. We are contacting ImageEn directly as well.
