It's almost impossible to get rid of it. Some scanners have what called a "descreening" function which is a fancy way of saying they blur the picture a little to get the dots to be less noticable. It happens when you scan printed material. Printing is done with little dots of ink, so when you scan... you're scanning dots.
My best advice is to scan it hella lot bigger than you need it, then reduce size and resolution.

From what I've learned of descreening, it's a filter that helps to remove the patterns of dots that appear from newsprint or magazine pictures. It's not so much a blurring effect, but a pattern removal. My scanner software allows me to select the level of descreening, plus it has presets for artwork, newsprint and magazines.
I agree that scanning larger than needed and reducing (in Photoshop, for example) will greatly increase the quality of your scans.
Look in your scanner's help section. Most have a 'moire removal' or 'descreen function'.

Thanks for the info. My scanner does indeed have the descreening function - but I've just scanned something else - so I'll have to play around with it next scan! It also has that newspaper/magazine/artprint function.
