I too have a 3200f and used it to scan hundreds of old photos to pc and burn them to dvd to play on my dvd player/widescreen TV. All perfect, colours and quality were and are great.
I scanned a photo and tried to print it out on my canon i350 and the colur reprodcution was very poor. I also printed a colour photo taken from my sony dsc-v1 on the same printer and the results were excellent.
I really never gave it much thought until I saw this thread. Sorry don't have a soloution but you may not be alone.
