Troubleshooting Barcode Problems
Barcode Quality
Ensure that the quality of the barcode label is acceptable. The ideal barcode 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 barcodes, such as those with broken areas,
smudges, or other irregularities. Environmental factors, such as exposure to dampness and
ultraviolet light, can also damage the barcodes during storage or use.
Ensure you are using an appropriate scanning technique. Refer to Scanning Technique ‚
page 2-22.
All parameters are not
available because they
have failed scheduled
QC analysis or
scheduled QC analysis
was not performed. View the events log to determine the event
causing the parameter to fail, and follow
the appropriate solutions for that event.
Analyze all the currently scheduled
controls for required QC.
Analyze QC for the failed level. Refer to
Performing Unscheduled QC Sample
Analysis
‚ page 4-4. If the results are
within range, turn the parameter on. Refer
to
Restoring Parameters ‚ page 4-12.
All parameters are out
of calibration because
they were turned off in
Setup and then turned
on again. Perform a 2-point calibration to make the
parameter available again.
Problem Probable Cause Corrective Action
The lights in
the
measurement
module are
turned off. The ambient operating temperature is at
the upper end of the acceptable range.
The measurement module lights are
turned off to help the system gain thermal
control. However, to aid visibility of the
sample path in the measurement module
during critical operations, the lights are
briefly turned on. For example, the lights
are turned on during sample and QC
analysis. No operator action is
required. You can
analyze samples and
report results.
When the ambient
temperature cools and
the system gains
thermal control, the
lights turn on and
remain on at all times.
