CL-NX Restrictions for the Barcode Check Function

Common Restrictions for the Barcode Check Function
•
When the product is powered on while the barcode checker is connected, the barcode checker is also powered on and emits a laser light. 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 product 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 product’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
Cutting according to the specified number of labels
Approximately 44 mm (1.73") from the print end position
Cut & Print
Approximately 44 mm (1.73") from the print end position
Dispenser
No restriction
Linerless (CL4NXonly)
Approximately 25 mm (0.98") from the print end position
•
The barcode check is not performed if the position at which the check starts is detected after the label feeding begins to stop. Define the label layout and position at which the check starts by keeping in mind that the distance required for stopping is proportional to the print speed.
•
Printed barcodes or 2D codes can be read only with a size at which their entire pattern is within the scanning range of the barcode checker. A reading error may occur depending on the print position.
•
This function cannot be controlled through the use of external signals (EXT).
•
The barcode check function for GS1-128 barcodes is supported by the 1.10.0 version firmware build or later. When using GS1-128, configure the barcode checker to enable the data output format for GS1-128. When CODE128 and GS1-128 are used together with a BL-1301 barcode checker, do the settings in each setting bank. At that time, assign to GS1-128 a number that is smaller than the setting bank of CODE128.
•
When powering on the product, do not connect or disconnect the barcode checker. The product may not operate properly.
•
Setting the decoding number for BL-1301 and WB1F-100S1S barcode checkers cannot be done from the product by the 1.10.0 version firmware build or later. If a barcode reading error occurs, change the count settings for reading (BL-1301: Decode match count / WB1F-100S1S: Verify count). Also, when using the optional barcode checker stand kit, exclude barcode types other than those to be checked. If any barcode type other than those to be checked is set, a decreased reading speed or misreading other barcode types may occur.
•
The barcode data that can be read for 1 item is up to 200 bytes per barcode and up to 200 Kb in total.
Restrictions When Using GFS4170
•
It keeps emitting a laser light while the product is powered on. To turn off the laser light, power off the product.
Restrictions When Using GFS4470
•
By the double-reading prevention function, the barcode checker may not read barcodes that are printed successively if they are within the readable area. Adjust the print position so that same barcodes are not within the readable area.
•
When printing composite symbols that use GS1 DataBar, the read data and print data never match if the barcode data is 16 digits or less. A comparison error occurs in comparison mode.
•
Though "\" (0x5C) specified in MAXI code, print data should be read as "\\" in the specifications. However, it may not be read as such, depending on the following data. For example, "\A" specified in print data should be read as "\\A" in the specifications, but it is actually read as only "A".
Restrictions When Using WB1F-100S1S
•
Multiple barcodes cannot be read at the same time.
•
When NUL (0x00) is included in CODE128 print data, only the data before NUL is recognized as reading data, and NUL and the data after NUL are ignored. A comparison error occurs in comparison mode. In readable mode, a reading error occurs only if NUL is specified at the beginning of the print data.
