7.4 Scanning Structure Append QR(iQR) Code Symbols
QR Code symbology can split data into a maximum of 16 blocks and encode each of them into a Structure Append
QR Code symbol (model 1, model 2) or iQR Code symbol. Structure Append QR Code scanning is possible only with
the same QR Code type.
The scanner can scan Structure Append QR Code symbols and restore them to the original data string in batch edit
mode or non-edit mode. The mode can be selected with the QR-coded parameter menu or configuration software
(ScannerSetting_2D).
Batch edit mode
This mode is supported by QR Code model 1 and 2 only.
If all Structure Append QR Code symbols split into a maximum of four blocks lie within the readable area, the scanner
reads them all once and then edits and sends them to the host computer.
Non-edit mode
Each time a single Structure Append QR Code symbol is read, the scanner sends the data read to the host computer.
When scanning Structure Append QR Code symbols, the scanner beeps in a different way from usual. That is, when
the scanner reads the first Structure Append code, it beeps twice and enters the Structure Append code scanning mode.
When the scanner completes the sequence of Structure Append code scanning, it beeps three times.
Note: If you scan any non Structure Append QR (iQR) Code symbol or a code other than a QR (iQR) Code
symbol midway through a sequence of Structure Append QR Code scanning, the scanner cancels the Structure
Append code scanning, discards the Structure Append QR Code data already scanned, and sends the code
scanned last.
Note: If the scanner switches to standby or the Structure Append code scanning interval exceeds approx. 3
seconds, then the scanner discards the data scanned and cancels the Structure Append code scanning sequence.
Note: If you scan a Structure Append code symbol of any other QR Code before completion of the current
scanning sequence, the scanner discards the data already scanned and starts a new scanning sequence.
