Scanner failure with application on Windows 7
I have an application (Java based running on JRE 5.11) which uses an external document scanner. The application is presently running on both Win7 and XP and the scanner is Canon 700F and 600F. The application is presently an APPV package and the scanner drivers get deployed through SCCM. On XP there is no concern but on windows 7 the application sometimes gives a scanner error "Cannot find TWAIN driver" when a scan job is initiated from the application. The users have found out a temp fix to unplug the Scanner USB and re-plug it and it solves the problem for the time being but it re-occurs. It seems to me that the scanners is going off to sleep and plug-out and plug-in back simply wakes it up and it works fine.
This also happens with the manual installation of the application on Win7.
Is anyone aware of any permanent fix to this.
