Does it have an LED light source?

You are probably getting one of two things, grain aliasing, or Callier
effect (due to the LED light source, which is a point light source and
exaggerates film grain).

See this link for a description of grain aliasing:

Personally, I think you are mostly having a problem with the LED light
source.  If that is the case, back off on your development a bit and that
will probably help...and it might take some experimentation to get it to
where you like it.  I shoot and scan D100 no problem, but I have a scanner
that has a diffuse light source.
