Imaging
Dolphin 9500/9550 terminals are equipped an image reader that reads 1D and 2D bar codes, OCR characters and can capture
images, such as signatures and gray scale pictures. The imager features a green aiming beam that is used to aim the image
reader against the bar code or item being read.
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 most any position.
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 imager's aiming beam should be centered horizontally across the bar code. When ALD is enabled, the reader
does not read matrix or postal codes.
Decoding a bar code - aiming the beam
1 Point the Dolphin 9500/9550 terminal directly at the bar code. The imager faces straight out.
2 Press the SCAN key on the Dolphin 9500/9550 to project the imager's green aiming beam. The aiming beam should be
oriented in line with the bar code to achieve the quickest read. A range of 4-10 inches (10-25 cm) is recommended.
3 Center the aiming beam over the bar code. The red Scan LED illuminates when the user presses the SCAN key, and the
green Decode LED illuminates when a bar code is successfully decoded and the terminal beeps.
Note: On the Dolphin 9550, you can use the Scan Trigger instead of the SCAN key. For more information, see
page 3-6.
