The forum adresses a very important subject, for finding the paper that works best it is one of the major problems/glitches with the Z3100:
Having tried numerous types of glossy and satin papers, using the Gloss Enhancer
I get still the best results with HP Professional Satin Photo Paper.
With some satin papers the gloss is really nice but then the dark reds are a problem or the gloss differential- or the wheelmarks- or all at once.
To find a glossy paper that shows no gloss differential is even more difficult; best results so far: HP High gloss contract proofing paper
for instance :
Ilford Gallery Smooth pearl paper: beautiful gloss- but weak dark reds and some gloss differential.
or Innova F type: wheel marks and pronounced gloss differential
maybe I am unlucky with my choices...?
