First, use attention

  Generally, the bar code printing device is in the direction indicated by the figure, the dotted line is the ribbon installation path, and the solid line is the label path. After the rewinding, the waste ribbon is not easily peeled off, and the smooth bottom paper of the waste label is wound on the reel before loading, and then the ribbon is fed. When installing labels, adjust the paper limiter according to the different label widths. The indenter spring is even to avoid the deviation of the printer label. The paper is measured when you use the printer for the first time.

Second, panel control

  PAUSE button: Pause and start printing

  FEED button: take a piece of paper

  CANCEL button: When the print data is transferred to the printer, but you do not need to print, you can press PAUSE first, then press CANCEL several times until the data light turns off.

  CALIBRATE: Label test. When a new specification label is installed, the parameters of the label are tested before they can be printed normally.

  Method: Press the PAUSE button first, then press CALIBRATE to measure the paper. The label has an acceleration process during paper measurement, indicating that the paper is correct.

  Note: The paper-finished label can be rolled back and the ribbon cannot be rolled back.

Third, equipment debugging

  Customers can choose the printing method according to their own requirements, select SETUP to enter the settings.

  Darkness------------temperature value

  Tearoff----------- label tear away position

  Printmode----------PEELOFF (tearing method)

  Ediatype---------NON-CONTINOUS (discontinuous paper)

  PrintWidth---------Print width

  ListFormats-------- format list

  ListSetup----------Setup List

  MediaandRibbonCalibrate------Test paper and ribbon

  LabelTop----------- label printing position top adjustment

  LeftPosition-------Print position adjustment on the left of the label

  Use the left and right black keys to modify the settings, and select the EXIT button to exit the settings. Finally, select the NEXT/SAVE button to save the setting data.

  After the debugging is normal, you can enter the setting LISTSETUP, then select the black button on the right to print the standard settings, save the label to proofread in case of failure.

Fourth, routine maintenance and regular maintenance

  In order to ensure the quality and long-term performance of the bar code printer, it needs to be cleaned regularly. The more frequently the bar code printer is used, the more often it should be cleaned. (Not often used = weekly cleaning; often used = daily cleaning)

  a, the cleaning of the print head

  (1) Always clean the print head regularly. The cleaning tool can use cotton swabs and alcohol. Turn off the power of the barcode printer. Keep the same direction when wiping (to avoid residual dirt when rubbing back and forth), and turn the print head up. Remove the ribbon, label paper, and use a cotton swab (or cotton) dipped in the print head cleaning solution to gently wipe the print head until it is clean. Then dry the printhead gently with a clean cotton swab.

  (2), to keep the print head clean, you can get good printing results, the most important thing is to extend the life of the print head.

  b, glue stick (PlatenRoller) cleaning and maintenance

  To regularly and regularly clean the bar code printer glue stick, the cleaning tool can use cotton swabs and alcohol to keep the glue stick clean, also to get good printing results and extend the life of the print head.

  During the printing process, the label paper will leave a lot of powder on the glue stick. If it is not cleaned in time, it will hurt the print head. The glue stick has been used for a long time. If there is wear or some unevenness, it will affect the printing and damage the print head. .

  c, cleaning of the drum

  After cleaning the print head, clean the rollers with a cotton swab (or cotton cloth) soaked in 75% alcohol. The method is to scrub the roller while rubbing it by hand, and after it is clean, dry it. The cleaning interval of the above two steps is generally three days. If the barcode printer is used frequently, it is best to do it once a day.

  d, cleaning of the drive system and cleaning inside the chassis

  Because the general label paper is self-adhesive, the glue is easy to stick to the shaft and channel of the transmission, and dust is added, which directly affects the printing effect, so it needs to be cleaned frequently. Usually once a week, the method is to scrub the shaft of the transmission, the surface of the channel and the dust inside the chassis with a cotton swab (or cotton cloth) soaked in alcohol, clean and dry.

  e, sensor cleaning

  To keep the sensor clean, no paper measurement errors or ribbon errors will occur. The sensor includes a ribbon sensor and a label sensor. The location is described in the manual. It is usually cleaned from three months to six months by scrubbing the sensor head with a cotton swab dipped in alcohol. After cleaning, dry it.

  f, paper guide slot cleaning

  The guide groove generally does not have a big problem, but sometimes the manual or label quality problem causes the label to stick inside the guide groove, so it is also necessary to clean it in time.

  g, warm reminder

  Bar code printer temperature is generally maintained between 10-24, not too high, otherwise it is easy to reduce the life of the print head, pay attention to the ribbon and label combination, generally coated paper with wax-based ribbon, synthetic paper with half or full tree Ribbon. In addition, the label paper should be kept flat, so do not make it uneven, otherwise the print head will be easily worn.

Fifth, print head pressure adjustment

  Adjust the printhead pressure according to the different media being printed. The pressure of the print head under normal conditions: adjust the nut to the highest position when printing is best.

  Otherwise, the long-term printing will cause deformation of the rubber roller, causing the ribbon to wrinkle and the printing effect is poor.

Sixth, LCD does not display and can not operate

  All the indicators of the printer are on, the LCD does not display and cannot be operated.

  Cause: The motherboard or EPROM is damaged.

  Solution: Contact your dealer, replace the motherboard or install the EPROM correctly.

Seventh, all the indicators of the printer flash and can not measure paper

  Cause: The sensor is faulty.

  Solution: Clean the sensor surface dust or contact your dealer to replace the sensor.

Eighth, the printer print process appears in the vertical line

  Cause: The surface of the print head is dirty with dust or the printer has worn out for long-term printing.

  Solution: Clean the print head with alcohol or replace the print head.

Ninth, the ribbon or label paper runs out in the printer printing

  Cause: The unevenness of the platen spring and the paper limiter are not adjusted according to the width of the watch.

  Solution: Adjust the spring and the paper limiter.

Tenth, the printing is not clear, the quality is poor

  the reason:

  1. The temperature is too low.

  2. The quality of the ribbon and label is too bad.

  3. The print head is not installed correctly.


  1. Increase the printing temperature, that is, increase the printing density.

  2. Replace the ribbon and label paper.

  3. Re-adjust the position of the print head, paying particular attention to the uniform height of the left and right.

Eleventh, the ribbon wrinkles

  the reason:

  1. The ribbon is not properly wrapped around the machine.

  2. The temperature setting is incorrect.

  3. The pressure and balance settings of the print head are incorrect.

  4. The media does not set the paper feed amount correctly.


  1. Reinstall the media correctly.

  2. Adjust the printing temperature as much as possible.

  Printing requirements:

  3. Reset the minimum pressure required for printing.

  4. Reset the correct paper feed amount of the media.

Twelveth, changing the parameter settings does not work

  Cause: The parameter settings may be incorrect. If the parameter settings are correct and the problem persists, it may be a problem with the motherboard.

  Solution: Re-boot, factory settings, and then set the parameters, and save forever. If you reboot, after the factory settings, use the printer by default, if it still does not work, only send the manufacturer to replace the motherboard.

Thirteenth, software related faults

  Using BarOne software to print Chinese characters, English, and barcodes is normal, while printing with other printing software cannot print Chinese characters.

  Cause: BarOne software directly controls the printer, while many other printing software prints through the windows driver. It is recommended to use a seagull drive only if you select the appropriate print program to print Chinese characters.

  Solution: Contact your product vendor, use a good driver such as the Seagull driver, or use a software that directly drives the printer, such as BarOne.

Fourteenth, paper replacement related faults

  The original printed label is normal, but since the other ribbon has been changed, the label is always printed and the paper is not normal.

  Cause: The printer has a memory that recognizes the ribbon and the label. Re-measurement is required when changing paper and ribbon.

  Solution: Take S400 (105SL) as an example. In the normal printing mode, press the MODE button three times and press the FEED button. At this time, a lot of paper is produced. After the paper is finished, the paper is automatically recorded in the printer. You don't have to take a new paper. The paper that ran out can be rolled back.

Fifteenth, printing large labels is always half, and the other half is empty.

  Printing small labels is normal, but printing large labels is always half and the other half is empty.

  Cause: The print memory is too small, and some information is lost when the label is too large.

  Solution: Contact your product vendor to increase printer memory.

Sixteenth. Which label printer should I use?

  How should users choose the label printer that suits their application? Consider the following questions when choosing a label printer:

  (1), the number of prints: If you need to print more than 1000 labels per day, you need a high-volume industrial-grade printer with a solid metal casing, such as Zebra105SL, XiII series. For smaller prints, you can use a desktop personal printer series, such as the ZebraGT810.GK888.

  (2), the size of the label: the general label printer can print 4" X6" label, which is in line with the current shipping label specifications. You can also flexibly print labels of different sizes according to your needs. For printing wider labels, you can choose between 170XiII and 220XiII models.

  (3), the content of the label: If you only need to print the barcode and text, the general label printer will be competent. But if you need to print different barcodes (such as the item number) or text (such as shipping labels) for each label, and you don't want to stop printing in the middle, you need a printer with a 32-bit processor, which can greatly improve Productivity. In addition, if you want to print high quality images on the label, you can consider using a 300dpi print head for better results.

  (4), printing speed: different styles of printers have different printing speeds, depending on the user's requirements for speed. Generally, label printers print at 2′′-6′′ per second, while higher speed printers (such as ZebraXiII series) can print 8′′-12′′ per second. If you need to print a large number of labels in a short time, high speed. The printer is more suitable.

  (5), application in different industries: printers used in production lines or warehouses should be more sturdy with metal casings, such as Zebra105SL and XiII series; and desktop personal printer series can be selected at the point of sale or office. Such as ZebraGT810.GK888, etc., because it requires less space and is easy to move.

Seventeenth, how to quickly print barcodes

  There are several ways to increase the speed of printing, you can use one or several of them.

  (1) Use parallel port instead of the serial port provided by Zebra. Although the serial port is simple to connect and uses a wide surface, the disadvantage is that the speed is slow. It is ok for general applications, but for high speed requirements, please use the parallel port interface.

  (2), select high-end printers. High-end printers allow for the highest print speeds than the low-end ones.

  (3) Set the print speed to high speed mode. The default setting is medium speed. However, the higher the speed, the worse the printing results. 4) Use a lower resolution printhead. Speed and effect can't be both.
