277.3 Barcode Reader modeThe Barcode Reader mode limits the vertical readable area to 15% at the center portion, as shown below, and the skewangle within the range of 6° ≥ θ ≥ 0°.In this mode, the scanning time required is shorter than that in the Normal Reader mode.However, the scanner cannot read 2D codes or multi-line bar codes. The Barcode Reader mode and the Point Scan mode(see Section 7.4) cannot be enabled concurrently. The one set last will be enabled.7.4 Point Scan modeIn the Point Scan mode, you can aim at a target code by matching up the cross provided at the center of the marker beamwith that code.If there is no code at that cross or the scanner cannot detect the marker beam due to high levels of ambient lighting, thescanner cannot read anything. The Point Scan mode takes effect only when the marker is permitted to light.The Point Scan mode and the Barcode Reader mode (see Section 7.3) cannot be enabled concurrently. The one set lastwill be enabled.7.5 Scanning a mirror image 2D codeIf you enable the mirror image scanning with the QR-coded parameter menu or the configuration software, the scanner canscan a mirror image 2D code as well as a normal image. Note that when the mirror image scanning is enabled, the timerequired for scanning may increase.7.6 Scanning a black-and-white inverted codeThe scanner usually scans a black-and-white normal code (black cells/bars on a white background). You can switch thescanner to scan a black-and-white inverted code (white cells/bars on a black background) or to scan both types of codeswhile automatically identifying them, using the QR-coded parameter menu or the configuration software.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 codespecifications.Readable area in the Normal Reader modeReadable area in the Barcode Reader mode(hatched section)
