Digital BW, The Print

Sorry to keep bringing this up but I still am having a lot of trouble with
darker prints on my R2400, even after calibrating the monitors for the third
time and this time disabling Adobe Gamma.  I have a tried a few different
papers and always use the proper profile and setting that paper dictates.  I
am not sure what to do next, maybe I can get a print done somewhere else of
one of my images and see if it comes out darker then.  Does anyone know of
any setting within the R2400 drive I might try and fool with?  I am thinking
of calling Epson next, thanks again.
