Any Updates people... it as it a ghost town..:+}
On Friday, I spoke with an HP telephone tech who admitted, finally, that "starwheel marks are an aspect of this otherwise fine product." Of course, there's an interesting Catch 22 in the "otherwise fine product." The on-board spectro was supposed to make it easy to use a variety of papers without having to make or buy profiles. Problem is, if you use almost any glossy/satin paper, you'll get starwheel marks in the dark (or not so dark) areas.
I've had the new pinch roller and starwheels installed and it makes a little difference, but not enough. I can't print on the new Ilford, Harman, or Hahnemuhle glossy/semi-gloss papers, so what's the point of the spectro?
Neil Snape wrote in a post elsewhere that if you've got starwheels, you've got marks. I checked my Epson 3800 and saw them there as well--but lighter than on the Z3100!
I've also read that HP Pro Satin presents no problems at all, and have ordered a roll. I'd prefer to print on Ilford Gold Fibre Silk, but it's simply unusable. Which reminds me that Michael R still uses and likes that paper. I wonder if he's found a workaround on the Z3100 or if he's doing all his printing on a machine with a vacuum transport (i.e. Epson).
