Hello Tim,

I have done a lot of scanning but never seen this effect before.  It looks like a limitation of the scanner. 
Have you thought of using a camera on a tripod to make copies of the original photos?  You are scanning at 
600dpi, but a decent camera should be able to exceed that easily if the originals are no larger than a 
postcard (150mm x 100mm).  Just make sure the photos are evenly illuminated and set the camera colour balance 
accordingly.
