Battery pack does not hold a full charge after recharging
• The battery pack may be faulty or worn out,
particularly if it is old. Replace it with a new one.
Laser scanner module does not read a label
• Make sure the label you are trying to scan is one
of the bar-code types that your PTC is
programmed to recognize.
• Move the scanner lens closer to or farther away
from the bar-code label. You may not be scanning
at the correct distance.
• Change the angle of the laser scanner to the bar-
code label. You may be too far above or below the
label or too far to the side to scan properly.
• Clean the scanner lens.
• The PTC’s application program may not support
scanned data at this particular field. Consult the
documentation for the PTC’s application program
to determine when the scanner and scan triggers
are enabled.
• Point the scanner at a blank surface and press one
of the scan triggers. Look for the scanning line
that appears on the blank surface when the
scanner is operating. If no scanning line appears,
follow your organization’s procedure to have the
laser scanner module serviced.
• If the bar code is oriented along the circumference
of a round tube, the scanner will not be able to
read it.
