Red, green and blue dots appear on images scanned with Kodak RFS 3570 Plus Film Scanner

When scanning Kodak Ektachrome 64, EPR, film transparencies, processed in a standard Kodak E-6 process, in size 6x6 cm (120 size film) using a Kodak RFS 3570 Plus Film Scanner I get very small red, green and blue dots (rather than spots). It appear the size of the dots are one pixel.

The scanner works well technically except for the small colored dots. It has not been used much lately. It has been stored in a book shelf, exposed to a normal office room environmental.

What might cause the little dots? More importantly: What can be done to remove them? Is there a software available that "sees" the dots and can remove them?

do the dots appear with other films also?
if not - the problem lies with the film

you can try upgrading the software also :  http://www.kodak.com/global/en/service/software/rfs3570Plus/dataSourceDownload.blind

I don't know if other films also show this effect, I have only used Kodak film.

Well, you ar right. However, I use size 120 - 6x6 cm - transparencies and it is not very common.

I have a suspicion it might be dust inside the scanner.

I found one softeare while searching for remedies: Imagenomic Noiseware. It very elegantly removed the majority of the dots.

in general, such an old device (from around 2000, or even 1990 ?) can be serviced easily
