Overview

The

Linear

Scanner,

technology, interrogates labels at up to

700 times per second to ensure that your

printed bar codes have the correct bar and

space widths, good contrast, and quiet

zones

readable.

microprocessor and proven decoding

algorithms provide accurate, high-speed,

operation.

Easy to use and fully integrated, the

Scanner has menu-selectable set-up and

control features including fault-handling

options that can void any label containing

an unreadable bar code and, if desired,

automatically generate a replacement.

This document provides all the information needed to operate the Scanner on a daily basis. The

illustration above highlights the Scanner's connection to the printer.

Performance

Several factors can affect scanning performance. For best results use carbon-based inks, label stocks with

a matte finish, and Print Contrast Signal (PCS – a comparison of the reflectance of the printed bars to that

of the background stock) that is as high as practical. In addition, you can program the Scanner using the

printer's front panel to meet your specific application requirements; see Setup and Configuration and

Label Layout, below.

High Throughput Applications

If your primary objective is to achieve the highest possible throughput rate with the minimum scanable

region, the following list identifies the parameters and settings that can maximize scanning and decoding

speed. When emphasizing throughput, however, other areas of performance may be affected. For

example, the number of non-reads could increase. If high throughput is critical, consider these settings:



Enable only those bar codes that you will be scanning.



Decrease the Redundancy Level or the Min Readable Height setting.

Bar Code Integrity Applications

If your primary objective is to ensure that the correct bar code data is read over a significant region of the

symbology, the following list identifies the parameters and settings that can maximize scanning and

decoding integrity. When emphasizing accuracy and data security, other areas of performance may be

affected. For example, throughput may be slowed. If bar code integrity is critical, consider these settings:



Increase the Redundancy Level or the Min Readable Height setting.



Slow the print speed and/or increase the bar code height.
