Operating One Dimensional (1D) Laser Scanners

•Is the laser beam scanning across the bar code?

•Once the scan beam has stopped, check the scanner window for dirt or fogging.

6.11.3Operating One Dimensional (1D) Laser Scanners

•Turn the Ikôn on. Wait until the unit has booted up completely.

Important: If an aiming dot is available on the installed scanner, the dot will be enabled for a configurable time period (including off), after which normal scanning begins. Refer to “Dot Time (msec)” on page 165 for details.

Double-clicking the button will override the aiming delay and initiate an immediate scan. Note that the aiming dot is standard on long-range and high visibility internal scanners.

•Aim at the bar code and press the scan key or the button. A scan beam and a warning indicator appear until a successful decode is achieved or six seconds have elapsed.

6.11.4Operating Two Dimensional (2D) Imagers

An imager takes a snap shot of a single bar code or multiple bar codes (at one time). It can find a bar code regardless of its orientation—that is, even a bar code printed at a 45 degree angle to the Ikôn will be decoded successfully.

Note: When scanning multiple bar codes, ensure that all of the desired bar codes are within the field of view of the scanner. It is possible that even when all bar codes are within the field of view, not all of them will be decoded. Only successfully decoded bar codes are passed to the application program. The application program then issues a warning, asking that you scan the missing bar codes.

When scanning a single bar code, ensure that only the desired bar code is within the field of view of the scanner.

Because imagers generally have a shorter depth of field than laser scanners, some practise may be required to find the optimal distance from the types of bar codes being scanned. Al- though the imager includes illumination LEDs, ambient light will help the imager decode the bar codes, especially if the bar code is far from the Ikôn.
