Symbol MS4404/MS4407 Integration Guide

Unlike bar codes that are typically printed on labels, a direct part mark (DPM) is a symbol that is marked directly on 
an item’s surface for permanent identification. These symbols are marked using methods such as laser etching 
and dot peening (see 

 for an example of a dot peen symbol). The DS3407-DP (DPM) digital 

reader scans these types of symbols.

To ensure the DS3407-DP digital scanner is programmed for DPM reading:

The DS3407-DP digital scanner can not read certain bar codes in near field. To ensure the digital scanner can 
read all bar codes, scan Far Focus on

.

If DPM scanning was disabled in the DS3407-DP digital scanner, scan Enable DPM Scanning (below).

Before scanning a DPM bar code, ensure that 

 is enabled.

When the DS3407-DP digital scanner is DPM enabled, the digital scanner reads all symbols including 
DPM, 1D, PDF417, etc. If DPM reading is not required, scan Disable DPM Scanning to ensure optimum 
scanner performance.

If you enable DPM Scanning, disable 

 when scanning a DPM bar code. 

Picklist performance is not guaranteed for DPM bar codes. 

Also, if you enable DPM Scanning, the scanner behaves as if the DataMatrix Inverse Autodetect setting 
is selected. When you disable DPM Scanning, the previous (user-selected) DataMatrix Inverse setting 
remains in effect. See
