Settings to Check Reading of Barcodes CL4-SXR

By using the barcode check function, you can use the scanner mounted to the product to read and verify the of printed barcodes to prevent the distribution of labels with invalid barcodes.

Cannot be used in Tear-Off mode.
Cannot be used with RFID models.
Use the barcode checker mount kit to mount the scanner.
Please disable the sleep mode when using the barcode checker (excluding USB connections).

Before connecting the scanner to the product, change its operating settings to enable communication with the product.

To use the barcode check function, install a compatible scanner and then configure settings using the following procedure.

If using a scanner not manufactured by Keyence, proceed to step 4.

From the settings screen, tap [Printing] > [Advanced] > [Barcode Checker] > [Mode] to select the barcode check function mode.
- [Disabled]
  Disable the barcode check.
- [Readable]
  When [Readable] is selected, it checks whether the printed barcodes are readable. Determines whether the number of barcodes read by the scanner matches the number of barcodes in the print data.
  If the number of barcodes read by the scanner reaches the number of barcodes in the print data, then they are judged to be readable.
  - They are considered readable even if the number of barcodes read by the scanner exceeds the number of barcodes in the print data.
  1. Media feed direction
  2. First barcode
  3. Second barcode
  - Barcodes created using methods other than barcode commands may not be read by the scanner, causing the Readable mode to function incorrectly.
- [Comparison]
  When [Comparison] is selected, it checks whether the barcode reading results match the barcode data in the print data. Applies to barcodes created with the barcode command.
  If the result of reading a printed barcode matches the barcode data in the print data, it is judged to be normal.
1. Media feed direction
2. First barcode
3. Second barcode
Initial value: Disabled
- To use Comparison mode, barcodes must be created using the barcode command. If graphic data (such as BMP images) or pre-printed barcodes are within the reading range, Comparison mode will not function properly.
- Even if Readable mode or Comparison mode is set, barcode verification is not performed if no barcode data is specified in the print data.
- Multiple barcodes on one label can also be checked. There is no limit to the number of barcodes, but a reading error will occur if a single barcode exceeds 100 bytes or the total barcode data exceeds 200 kilobytes.
Set [Interface] to [RS-232C].
Power off the product and then power it back on.
When you power on the product, the scanner will also turn on automatically.
- When the scanner powers on, a laser beam is emitted from the scanner. Take great care to avoid direct eye contact with the laser beam.
- Do not plug or unplug the scanner while the product is powered on. This product may not operate correctly.
When the connection to the scanner is complete, is shown in the status bar.
From the settings screen, tap [Printing] > [Advanced] > [Barcode Checker] and confirm that the connected scanner is shown in [Barcode Reader].
Place a label with a printed barcode within the scanner's reading range.
Tap [Reading Test] to perform a barcode reading test.

If the reading is successful, the type of barcode read and its data will be displayed on the screen.
If reading fails, or if the displayed reading result is incorrect, adjust the position of the scanner.
If necessary, configure the following advanced settings.

[Set No.of Barcodes]

Appears if you select [Readable] for [Mode].

When [Commands] is selected, the barcodes created with the barcode command are subject to read checks.

When [Settings] is selected, barcodes created using methods other than barcode commands (such as graphic data or pre-printed barcodes) are included in the read checks.

Initial value: [Commands]

[Barcodes per Label]

When [Settings] in [Set No.of Barcodes] is selected, then specify the number of barcodes on one label.

If you set [Start Position] to exclude the first barcode from the check target, specify the number of barcodes without counting the excluded barcodes.

Initial value: 1

[Start Position]

Adjust the start position for checking the barcodes (the position where the scanner starts reading).

The scanner begins reading after each label has passed the length specified in this setting from the print start position.

This is used when multiple barcodes are printed on each label and you want to exclude the first barcode from the check.

203 dpi: 10 to 20,000 dots (initial value: 72)
305 dpi: 15 to 18,000 dots (initial value: 108)
609 dpi: 30 to 9,600 dots (initial value: 216)

[VOID Print]

Set to print / marks on the corresponding label in the event of a reading error or a comparison error.

After printing VOID, the same barcode will be issued and checked until the number of retries specified in [Retry Count] is reached.

This function cannot be used when [Print Mode] is set to [Dispenser] or [Linerless Cutter].
This function cannot be used when the length of the print data is less than 8 mm (0.31").
The maximum length of the backfeed amount for VOID print is 45 mm (1.77"). However, if the length of the image printed on the label being checked is less than 45 mm (1.77"), the backfeed amount will be the length of that image.
When this function is enabled, even if the cutter does not cut during the cutting operation, a VOID print will be forced if a comparison error occurs.

Initial value: Disabled

[Retry Count]

Set the number of times the same barcode is reprinted and checked after VOID print. (0 to 10)

Appears if [VOID Print] is enabled.

Initial value: 0

[Host Notification]

The barcode check results for each label are sent back to the host with the following information.

If the check succeeds: BV,OK
If the check fails: BV,NG

Initial value: Disabled

[Logs]

Copy or delete the log data that is automatically generated when barcode readable check or comparison check is successful or an error occurs.

This function can be used only when there is barcode check log data in the product.

When the log file reaches its maximum size (1 MB), the new log data overwrites the older log data.

You can tap [Copy] to copy log data to a USB memory if you have connected a USB memory.

Barcode check log data is created in the following format.

The output results for each log item differ depending on whether the barcode is read or verified.

Format ID	Description
YYYY/MM/DD	Date when read (year/month/day)
hh:mm:ss	Time when read (hour : minutes : seconds)
ZZZ	Time zone
TTTTTTT	Total number of labels issued since the product was started If the total number of labels issued is 8 or more digits, the number of digits output will also increase.
IR	Number of read data received after reaching the check start position If the check result is "IGNORED," it will be "00."
SRSR	Read data size (bytes)
drdr...	Read data
RRRRRRR	Check results SUCCESS Always OK in Readable mode. In Comparison mode, this indicates that the read data and the print data match. FAILURE In Readable mode, this indicates that the scanner did not read the data for the printed barcode. In Comparison mode, this indicates that there was a mismatch between the read data and the print data. IGNORED Indicates that the data was read outside the period between the start and end of the check while the product was operating.
IC	Number of print data to be checked If the check result is "IGNORED," it will be "--."
SCSC	Print data size (bytes) If the check result is "IGNORED," it will be "----."
dcdc...	Print data If the check result is "IGNORED," nothing is output.
