Chapter 3: Getting To Know Your 7535
Operating One Dimensional (1D) Internal Laser Scanners
3.7.5 Operating One Dimensional (1D) Internal Laser Scanners
• Turn the 7535 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” on page 136 for details.
Double-clicking the trigger 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 trigger. A scan beam and a warning indicator appear until a successful decode is achieved or six seconds have elapsed.
3.7.6 Operating Internal PDF Laser Scanners
This scanner decodes PDF417 two-dimensional bar codes.
• Turn the 7535 on. Wait until the unit has booted up completely.
• Aim at the bar code and press the scan key or the trigger. The beam expands into a rectangle covering the bar code to properly scan it. The scan beam and a warning indicator are visible until a successful decode is achieved or three seconds have elapsed.
3.7.7 Operating Internal Two Dimensional (2D) Imager Scanners
An imager scanner 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 7535 will be decoded successfully.
Because imager scanners 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. Although the imager includes illumination LEDs, ambient light will help the imager decode the bar codes, especially if the bar code is far from the 7535.
• Turn the 7535 computer on. Wait until the unit has booted up completely.
• Aim at the bar code and press the scan key or the trigger.
