Wand Scanning Hints
•
Scanning should be uniform and rapid; fast scans work best.
•
Relax your hand - a stiff or jerky action won't produce good results.
•
Start scanning in the white space before the label, about a centimetre
from the bars.
•
Take care not to wander off part way through the barcode, and
follow through into the white space following the barcode.
•
The wand must remain in contact with the label, but there’s no need
to press down hard.
•
Labels are easiest to read on a flat surface.
Barcode Label Hints
•
You should try to avoid using poor quality labels or inappropriate
types of barcodes. If in doubt, discuss this with your dealer.
•
Try to guard against barcode damage such as:
♦
Liquid spills on the barcode symbol (coffee, etc).
♦
Ink smearing or erased bars which may result from excessive
pressure on the barcode surface.
♦
Scratches through the barcode symbol.
♦
Writing across the barcode symbol.
•
The use of a protective covering, such as “invisible” sticky tape or
clear Contact, will prolong the useful life of a barcode label.
The Z4 DataTraq has been designed to provide a high first read rate
when a good symbol is scanned. A low first read rate is normally
caused by either a damaged barcode symbol or improper operation of
the system by the operator.
