Scan large, blur slightly, then shrink later...
Scan your image in at the highest resolution possible. Scanning at 4 times higher than the final resolution works reliably well. Also rotate the image on your scanner so that it isn’t straight. Sometimes, scanning the original rotated to some angle (for example 15°) then rotating it back in an image editing software in conjunction with blur effect may further decrease the affect of moiré patterns. Next go into PhotoShop straighten the image. Then apply the Despeckle, Median or Blur filter to soften the pattern (play with each to decide which one works the best for you). Finally, resample it down to your desired resolution. You may also need to use the Unsharp Mask for a bit more sharpening.
