Scanning Structured Append QR (iQR) Code Symbols

QR Code symbology can split data into a maximum of 16 blocks and encode each of them into structured append Code

symbol (model 1 or 2). Structured append code scanning is possible only with the same QR Code model.

The scanner can scan structured append symbols and restore them to the original data string in edit mode, batch edit mode, and

non-edit mode, which you can select using the command, the QR-coded parameter menu or configuration software (QR

Setting).

Edit mode

The scanner accumulates and edits split QR Code symbols read and then sends the edited data to the host computer. If the total

data volume of split QR Code symbols exceeds 8 kilobytes, a read error will result and the accumulated data will be discarded.

Batch edit mode

If all the split QR Code symbols to be scanned 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 split QR Code symbol is read, the scanner sends the data read to the host computer.

When scanning structured append QR Code symbols, the scanner beeps in a different way from usual. That is, when the

scanner reads the first structured append code, it beeps twice and enters the split code scanning mode. When the scanner

completes the sequence of structured append code scanning, it beeps three times.

Note: If you scan any non-structured append QR Code symbol or a code other than a QR Code symbol midway through a

sequence of structured append QR Code scanning, the scanner cancels the structured append code scanning, discards the

structured append QR Code data already scanned, and sends the code scanned last.

Note: If the scanner switches to standby in auto-off mode (after approx. 5 seconds of holding down the trigger switch or by

releasing the trigger switch within 5 seconds) or the split code scanning interval exceeds approx. 3 seconds in any trigger

switch operating mode except auto-off mode, then the scanner discards the data scanned and cancels the structured append

code scanning sequence.

Note: If you scan a structured 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.
