Restrictions for the Barcode Check Function
Common Restrictions for the Barcode Check Function
• When the printer is powered on while the barcode checker is connected, the barcode
checker is also powered on and emits a laser light for a few seconds. Be sure to keep
the laser away from your eyes.
• The reading accuracy of barcodes or 2D codes is affected by label conditions (label curl,
print quality, etc.) and the usage environment (ambient light, temperature, humidity, etc.), and
readability is not guaranteed. Be sure to do a test read with the barcode checker you will use in
advance.
• The types of paper that can be used are the same as the printer specifications. If the label color
is silver or laminated, however, it makes it difficult for the barcode checker to read the barcode,
as the light of the barcode checker may cause a reflection on the label surface. Be sure to do a
test read carefully in advance.
• Design the label layout so that barcodes or 2D codes do not remain within the scanning range
of the barcode checker at the completion of printing. If the barcode of the previous label remains
in the scanning range at the start of the next printing, the barcode checker may read the same
barcode twice. The image below is when in continuous mode. As the stop position differs
depending on the printer’s print mode and commands, be sure to check your label layout
carefully in advance.
(1) Media feed direction
(2) Print head position
• Barcodes printed within the following range from the print end position cannot be read and a
reading error inevitably occurs. As the following table is only for a reference, be sure to do a test
read carefully in advance.
Print modes Ranges to be avoided
Continuous Approximately 11 mm (0.43") from the print end position
Cutter
Cutting every label
Approximately 25 mm (0.98") from the print end position
