Scanning A Mirror Image 2D Code; Scanning A Black-And-White Inverted Code - Denso QK31-R User Manual

7.1.4 ADF script mode
The ADF script refers to a simple program language designed for editing of data read. It enables the following
functions.
(1) Extracting data that is fixed or variable in length
(2) Supporting Application Identifiers (AIs) in GS1-128, GS1 DataBar and GS1 Composite symbols
(3) Sorting data blocks into the specified order
(4) Collating data for verification
(5) Outputting same data repeatedly
(6) Performing four arithmetic operations including residue calculation, e.g., transformation of units
(7) Substituting data
(8) Comparing character strings
The ADF script mode can be programmed with the configuration software (ScannerSetting_2D). To configure the
scanner with the ADF script, transfer the script to the scanner or generate an ADF script QR code symbol with the
configuration software (ScannerSetting_2D) and use the scanner to read the symbol.
For the specifications and instructions for use of the ADF script, refer to the ADF Script User's Guide.
Note: The ADF script mode cannot be used together with the GTIN format conversion or any of other edit modes
(data extraction mode, data substitution mode, and data blocksorting mode).
7.2 Scanning a reverse Code
The scanner can scan symbols viewed from the front surface or from the back surface. Scanning of 2D Code viewed
from the back surface can be set to enable(setting to read Reverse code) or disable(setting to read Normal mode) using
the configuration software. If scanning of 2D Code viewed from the back surface is enabled, scanning time of 2D
Code may become longer.
7.3

Scanning a Black-and-white Inverted Code

The scanner usually scans a black-and-white normal code (black cells/bars on a white background). You can switch
the scanner to scan a black-and-white inverted code (white cells/bars on a black background) or to scan both types of
codes while automatically identifying them, using the QR-coded parameter menu or the configuration software
(ScannerSetting_2D).
Note that the automatic detection scanning may take more time than normal code or inverted code scanning.
A black-and-white inverted code requires a black quiet zone of more than the number of cells defined in the code
specifications.
