You use the spectrophotometer to measure color patches by scanning each strip of patches in order.

1. For more accurate measurement, place several sheets of plain white paper beneath the calibration page or use a backup board if it is available.
2. Orient the calibration page so that strips are horizontal and the scan direction (indicated by the arrow at the beginning of the strip shown in the display or on the calibration page) is left to right.
3. Hold the spectrophotometer with its length perpendicular to the scan direction, and place the tip of the sample aperture on the white space at the start of the specified strip.
4. Press and hold the spectrophotometer button and wait for a signal (an indication on the display or a sound).
5. After you see or hear the signal, slide the spectrophotometer at a slow but consistent pace across the strip.
6. Take about five seconds to scan the length of the strip.
7. Release the button when all the patches in the strip have been scanned and you reach the white space at the end of the strip.
8. Repeat for all the strips in the order indicated on the display. For black-and-white printers, there is a single strip.
9. When all the strips have been scanned successfully, click Continue to view the measurement results.
