Z4 DataTraq

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.
