You use the built-in laser scanner on the JANUS 2020 reader to scan and enter
bar code data. The laser scanner emits a beam of laser light that is visible on a
bar code label as you scan it. The reader decodes the bar code label and enters
the data or command you scanned.
Warning
Do not look directly into the window area or at a reflection of the laser beam
while the laser is scanning. Long-term exposure to the laser beam can damage
your vision.
Avertissement
Ne regardez pas directement la réflexion d’un rayon laser ou dans la fenêtre du
laser lorsque celui-ci est en opération. Si vous regardez trop longtemps un
rayon laser, cela peut endommager votre vue.
Scanning a Label With the Reader
There are two types of scanners available:
• Standard laser scanners can scan bar code labels up to 25 inches away,
depending on the bar code height and density.
• Long-range laser scanners can scan bar code labels up to 60 inches away,
depending on the bar code height and density.
To scan a bar code label with a standard scanner
1. Press to turn the reader on.
2. Hold the reader at a slight angle a few inches from the bar code label. The
laser scanner window must be pointing toward the label.
3. Pull and hold the yellow trigger on the reader to activate the scanner. Direct
the beam so that it falls across all bars in the bar code label. After reading
the label, the reader beeps and the scanner turns off.
4. Release the scanner trigger.
