So you are throwing every possible patch in PrintFIX PRO at a printer that 
builds its neutral entirely from color ink. Precision is a wonderful thing, but 
it won't fix some issues. The light source you view images under will change 
the color tint of colors, especially darker colors, especially on glossy media, 
with the R1800. But that type of illuminant metamerism typically shows as a 
rusty tone in one direction, and a green on in the other. 

I'd suggest you look at the media settings you are choosing to print your 
profiling targets. Even if there is one with the same name as the paper you are 
using, its not necessarily the best choice for custom profiling. See if   you 
can get a better range of shadow tones from another media setting, then try 
profiling it. But don't bother with 729+238, just see what the standard 225 patch 
profile looks like first... also, be sure to let your targets dry before 
reading. In humid conditions, with glossy papers, three days might not be too much 
for some inks!
