This appendix explains how to set up and calibrate the following color measurement 
instruments:

• EFI Spectrometer ES-1000 hand-held spectrometer

• X-Rite DTP41 automatic scanning spectrophotometer

• X-Rite DTP32 automatic scanning densitometer

The EFI Spectrometer ES-1000 is a hand-held 

 that measures the 

 reflected from printed output and other colored materials, as well as the 

 of printed ink and toner. It uses the density measurements to effectively 

calibrate the EX7750.

To use the ES-1000 for calibration, you must first set it up for use with your computer. 
Follow the instructions that accompany the ES-1000, and connect the ES-1000 to 
your Windows or Mac OS computer by connecting the USB cable to a free USB port, 
or to a USB hub that features a separate power supply.

Because of its power requirements, the ES-1000 will not work if it is plugged into the 
USB port on your keyboard.
