Appendices

Label Speed

Applies to both picket fence and ladder oriented labels. If your application allows it,

slowing label speed (the time in seconds that a label is fully within the scan width of

the scanner) is an effective way to increase the number of decodes.

Raster Height

When using the raster features, you can increase the decode rate by decreasing the

height of the raster image.

Raster Sweep Rate

Slowing the number of sweeps per second to the minimum needed will result in more

scan lines passing over the label and a higher decode rate.

Laser Framing

Narrowing the laser frame may not increase the decode rate, but it will minimize the

opportunity of extraneous reads.

Label Dimensions, Label Density, and Label Ratio

Not usually an option in most applications, but changes to label parameters can affect

number of decodes calculations and possibly decode 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 will receive more scans. Changing

label density and/or bar code ratio is another way ranges, decode rates, etc. can be

altered.

Gain and Tracking

These adjustments, typically made by qualified technicians, are referenced in the

Scanner Setup menu (see “Save Active Settings including Factory for Power-on” on

page A-26). Changes to tracking will generally have a limited affect on decode rates.
