QTR-Quadtone RIP

Just got a 2200 (used) and wanted to try out the QTR.  My monitor is 
calibrated with a Spyder 2.  First attempt on Epson Enhanced Matte and 
everything was printing very, very dark.  I had to slide the Gamma all 
the way to the left to get it even close.  I ran the calibration page 
at 100% and the Ink Limit looks to be around 40-45%.  Is this normal? 
I don't want to start the next step if I'm doing something wrong or if 
there is something up with the printer.  Thanks.
