Adjust Other Scanning Parameters
This section lists various adjustments that may improve read rates.
After changing any of the parameters described in this section,

c. Compare the new read rate results with those obtained before
changes were made.
Range
Adjusting the label’s range, if possible, is one of the quickest and most
effective ways to improve read rates. However, in some applications you
may need to select a less than optimum range, or one that is beyond the
fringes of the ranges listed in table 1-1 on page 1-3.
After making changes, repeat Step 3, “Calculate Number of Scans,” on
page 1-4 and Step 7, “Do Read Rate Test,” on page 1-10.
Scan Width
Increasing scan width will increase the number of scans in a picket fence
oriented application. Scan width is linked with scan range (as shown in
table 1-1 on page 1-3) and changing one will usually require a change in the
other.
After making changes, repeat Step 3, “Calculate Number of Scans,” on
page 1-4 and Step 7, “Do Read Rate Test,” on page 1-10.
Label Speed
Applies to both picket fence and ladder oriented labels. If your application
allows it, label speed (the time in seconds that a label is fully within the scan
width of the scanner) is an effective way to alter the number of scans.
After making changes, repeat Step 3, “Calculate Number of Scans,” on
page 1-4 and Step 7, “Do Read Rate Test,” on page 1-10.
Label Dimensions, Label Density, and Label Ratio
Not usually an option in most applications, but changes to label parameters
can affect number-of-scan calculations and possibly read rates.
If your application allows it, shortening the length of a picket fence label
means the label will be in the scan range longer and hence receive a
greater number of scans. Increasing the height of a ladder label means it
