The Scan Dual IV will not initialize on startup although the door is closed.

You can find it here.

Konica Minolta Photo Imaging Europe GmbH DiMAGE Scan Dual IV

Have you right clicked on the .exe file of windows 7 executable for the Minolta scanner to select compatibility to switch it back to xp.Have you tried to use third party twain drivers for scan software such as silverfast or vuescan instead?

I used this solution from KainAnderson
1) Install the Konica Minolta XP software in Win 7.
2) Plug in your DImage Scanner into a USB port and turn it on with the door closed. It may detect and install the original Konica Minolta Driver.
3) Create an empty folder on you harddrive (for instance go to my computer, double click on the c: drive, then right click and create a new folder named newminolta).
4) Open windows notepad and copy the following into it:

; scanners.inf -- Test Vista Minolta Film Drivers
;
;
; To remove this driver and install the original
; manufacturer's driver, go into Device Manager,
; open Imaging devices, then click on the scanner name
; with the right mouse button and choose Uninstall.

The scanner doesn't work with vista. Use VUESCAN from www.hamrick.com

DS Dual 4 even works with SnowLeopard on a CoreDuo MBP. But it doesn not support Autofocus when used under USB2. You have to use a USB1.1 Port, if you want to use autofocus function. Every time the software crashes, because you tried e.g. to use autofocus with USB2, you will have to close the application, go to the folder User/Library/Preferences/DS Dual4/... and look whether there is a file name something like "MFSlib...." and pull it to the trash bin. You can start the application again. PS.: Your keyboard USB port is a USB 1.1 port!

1) Install the Konica Minolta XP software in Vista/Windows 7.
2) Plug in your DImage Scanner into a USB port and turn it on with the door closed. It will detect and install the original Konica Minolta Driver.
