I am running a Xerox Doc260 with Fiery EX260. I have the XRite DTP20UV Spectrophotometer. The device list on the computer shows the DPT20 installed as a USB device. When I open the Fiery Calibrator screen there is a drop down box to select Measurement Method, but the DPT20 is not one of the devises listed and I don't see a way to add it within the Calibrator screen. How can I add this to the Calibrator so I can run calibration? Thanks in advance.
