Hi,

I went through a similar experience with a slight magenta cast on B&W 
with Epson R1800; the earlier version of the R1900. The problem is  
the R1800 has only one black ink and no gray ink so the grays must be 
produced by a combination of the colors. A very difficult task. See 
my thread starting with message 3112 for how I iterated the profile 
process to get pretty close. You will have to use the advanced 
profile process.

I'm sure CD will chime in shortly.
