3 - 2 Symbol MS4404/MS4407 Integration Guide

Illumination System

The Symbol MS440X includes an illumination subsystem, consisting of four red 635 nm LEDs, to meet the image
capture and decoding requirements throughout the full range of ambient lighting (total darkness to full sunlight).

Illumination Control

The Symbol MS440X can capture images with the illumination subsystem turned on or off, accommodating images
that are close to the wavelength of the illumination. For example, since LED illumination is red, it may be desirable
to shut off the illumination when capturing a printed image in red ink.

Focus Control

The Symbol MS440X has two focus positions controlled by an electromagnetic motor, which is under dynamic
software control and is independent of the illumination and aiming systems. The operating modes of the motor are:
•
Near Focus
•
Far Focus (default).

Imaging Tips

When imaging, ensure the bar code is within the decode range (see
within the aiming pattern. The green decode LED lights and the imager beeps to indicate a successful decode.

Capturing Data

Place the symbol in any orientation within the aiming pattern. Ensure the entire symbol is within the rectangular
area formed by the brackets in the aiming pattern. The red laser aiming pattern turns on to assist in aiming.
