Using the Imager

The terminal houses a compact image engine that instantly reads all popular 1D and 2D bar codes and supports omni-directional

aiming and decoding for greater flexibility in real-world settings. The image engine can also capture digital images, such as

signatures and pictures of damaged inventory. Images are saved in industry-standard file formats.

Decoding

The terminal supports two types of image decoding for use in various bar code reading and imaging applications: full-area

imaging and Advanced Linear Decoding (ALD).

Full-area Imaging

Full-area imaging provides omni-directional reading of linear and non-linear 1D and 2D bar codes, OCR, signature capture, and

picture taking. When reading all bar code types using full-area imaging, a positive read can be obtained from many positions;

see Scanning Position Options on page 4-7. To achieve the best read, the aiming beam should be centered horizontally across

the bar code.

ALD

ALD provides fast reading of linear and stacked linear bar codes. To achieve a positive read when reading linear 1D and PDF417

bar codes, the green aiming beam should be centered horizontally across the bar code. When ALD is enabled, the reader does

not read matrix or postal codes.

To Decode a Bar Code

1. Point the Dolphin terminal directly at the bar code. The imager faces straight out the top panel.

The aiming beam should be oriented in line with the bar code to achieve optimal decoding. A range of 4-10 inches (10-25 cm)

from the bar code is recommended.

2. Project the imager’s green aiming beam by:

• Pressing and holding the SCAN key on both the Dolphin 9500 and Dolphin 9550.

• Pressing and holding the Scan Trigger on the Dolphin 9550 and the Dolphin 9551.

3. The scan LED lights red.

4. Center the aiming beam over the bar code; see Scanning Position Options on page 4-7.

5. When the bar code is successfully decoded, the decode LED lights green and the terminal beeps.

6. The bar code information is entered into the application in use.
