<correction>
You set what is pure white and pure black via calibration. It might  
work flawlessly out of the box, but I had to calibrate it for my  
setup, so dry down isn't built-in, is just a matter of setting it  
comparing the reference strips with your own dry strips. Once that is  
done, you can forget about dry-down forever (while nothing changes on  
that paper side)

yup, it's a great piece of equipment that saves lots of time.
