Scanning Technique; Bar Code Quality; Resetting The Bar Code Scanner - Bayer HealthCare RapidPoint 400 Series Service Manual

Scanning Technique

Use the following technique to ensure that you operate the bar code
scanner correctly:
• Hold the scanner at an angle to the bar code, not directly over the bar
code and not touching it.
• Scan the entire bar code. Move the scanner to the distance that allows
the beam to scan every bar and space.

Bar Code Quality

Ensure that the quality of the bar code label is acceptable. The ideal bar
code label has clean, clear, straight, fine lines with high contrast between
light and dark areas. A white background with black print provides the
highest contrast.
Label quality can interfere with correct scanning. Avoid using labels with a
highly laminated surface or with poorly printed bar codes, such as those
with broken areas, smudges, or other irregularities. Environmental factors,
such as exposure to dampness and ultraviolet light, can also damage the
bar codes during storage or use.

Resetting the Bar Code Scanner

Reset the bar code scanner if the scanner no longer scans bar codes that
it scanned before.
Use this procedure only after performing all the corrective actions
