changing destination scan

I am currently running Windows Vista Home Premium. I have been able to get
all of my printers (HP 4L, HP 750 PSC & HP 7660 PhotoSmart) installed and
running. My problem is that I would like to add a scan destination on my 750
PSC. Right not it will only scan to a listing given by the program, which
does not include MicroSoft Word. I would like to be able to scan some of my
documents to Word but don't know how to add this destination to the list that
already exists. Anybody have any ideas or clues on how I can do this? Vista
only allows it to scan to Windows Photo Gallery which automatically makes it
a JPG file or other photo file so I will have to use the scan function that
comes with the scanner.
