During the calibration, you
must run the
conveyor at the same speed used in normal
production runs.
1) Follow steps 1–5 of the “Photo Registra-
tion for Product Rejects” section on
page 4. There are two parts to the calibration process.
• Learn the X and R noise thresholds.
• Learn the detect levels (for both the X
and R signals).

Press the Go button to select “middle” for
photo registration.
