Signature Calibration
.
Note. Before performing the Signature Scanner calibration, first verify that the two switches and
the thumbwheel on the Logitech Scanner are set as follows:
a. Looking at the Scanner from the rear, on the left side, set the switch nearest the
front (gray level or bi-level) to the "/" position ("a" in Figure 4-11).
b. Also on the left side of the Scanner, set the thumbwheel (contrast adjustment) to
the center position ("b" in Figure 4-11). (If the signature on a finished print is too
light or dark, move the thumbwheel toward the light or dark band accordingly.
c. Finally, on the right side of the Scanner, set the dots/inch switch at "2" ("c" in
Figure 4-11).
