1
Overview
With the H-Class Linear Scanner option and menu-selectable functions that include voiding and
replacement generation, labels can be interrogated at up to 700 times per second to ensure that correct,
readable symbologies have been printed.
Use the sections of this document to find needed information. As a starting point, if your Linear Scanner
arrived factory-installed, see “Controls and Features, Performance, and Configuration” to begin use;
otherwise, proceed to “Installation.”
Installation
If installing the kit, verify the experience level of the installer, the package contents, and the tools needed
before following the steps below.
CAUTION
Only qualified service personnel should perform this installation. For your safety and to
avoid printer damage, always turn OFF the power switch and unplug the AC power cord
before this installation and whenever performing service.

CAUTION
The Pivot Mount should never be over-extended. The use of controls, adjustments, or
procedures other than those specified herein may result in hazardous LED light exposure.
Class 1 LED power up to 15 mW in a 0.1 ms pulse at 635-670 nm could be accessible in
the interior of the Linear Scanner.
Performance Considerations
Printing with the scanner is a seamless operation; however, consider some important factors that can
affect performance:
7
Integrity and Speed
If the primary objective is to ensure that correct data is read over a significant region of the
symbology, maximize integrity by (1) increasing the REDUNDANCY LEVEL or the MIN
READABLE HEIGHT setting, (2) slowing the print speed, and (3) increasing the bar code height.
When emphasizing data accuracy, the allowable maximum throughput rate may be affected.
If the primary objective is to achieve the highest label throughput rate, maximize speed by (1)
decreasing the REDUNDANCY LEVEL or the MIN READABLE HEIGHT setting, and (2)
increasing the print speed. When emphasizing throughput, data reliability may be affected.
Media and Ribbon Selection
For best results use carbon-based inks on matte-finished label stocks to achieve a high print contrast.
Label Layout
For proper recognition, the Linear Scanner must be positioned over the bar codes, and the codes
used and the label layout must meet certain requirements:
The bar codes must be placed in the picket fence orientation, with proper quiet zones, and a
narrow bar resolution that is no less than the scan resolution position.
If encoding the same information in multiple-up bar codes arranged in ordered columns (see
below), allow at least ¼ inch of white space between the rows.
104 104 104
104 104 104
1/4 inch (6.5 mm)
Row
Column
Print
Direction
When printing bar codes on small labels, avoid the possible need for backup repositioning by
placing the code(s) near the leading edge of the label.
Although a reduction of print speed may actually improve throughput, to maintain proper
detection when printing small bar codes at high speeds the following parameters should not be
exceeded:
Minimum Bar Code Height Maximum Print Speed (IPS)*
1/16 inch (1.5 mm) 8
1/8 inch (3 mm) 10
* Inches per Second
