I picked up a glossy colour leaflet in a shop and asked them to run a copy on this printer. The first things I noticed is that it has a very slow scan (compared to my ancient Canon MP140 from a few years ago...).
Secondly, the image is degraded. There was a small colour 'photo' quality section which appeared to be transformed to dotty shading (rather than smooth). The top of a scanner (smooth grey) came out mottled, like a very noisy high ISO photo... and a shadow under the scanner came out in dot shading - not solid graduated shading.
Overall, text looked okay - but I think that the comments I saw in other reviews (graphic printing is sub-par) are accurate. To me, graphics looked nasty!
