Barcode printer to print barcode is of course a barcode printers (Zebra bar code nonsense, huh). Ordinary printers use primarily in shopping malls. Barcode printer barcode printer's print head to the ink printed ribbon (equivalent stylus ribbon) on the print paper (there is a certain standard size paper sticker style) in the bar code. Although you can use as a normal label printer (if you took too narrow a word :)), but most of the time (99.999999999%) or be used in the print product barcode. Another example zebra GT820 bar code machines, now soon the New Year, many of my friends have to buy a train ticket home, on the train bar code is printed out these bar code equipment. (It seems barcodes in our lives all the time or do not exist) the biggest difference between an ordinary bar code printers and printer is printing thermal bar code printer is based, ribbon for print media (or directly using thermal paper) finished printing, this printing method with respect to the normal printing mode of the biggest advantages is that it can achieve a continuous high-speed printing at unattended. Why print head a needle, how to judge the print head broken: bar code printer head is composed of a row of heating elements combination with 8 or 12 heating elements inside the print head 1MM length of the common bar code printers, width of the heating element is visible very small. Print head disconnection phenomenon is often relatively easy to determine, generally you will find the printed label sheet from top to bottom has a straight, fixed blank lines. Print head is usually broken beyond repair barcode machine, only replace the print head, and the price is not cheap. Second, the main cause of print needle of: A. label paper dust on the surface. For precision heating units, the tiny dust like a large stone scratched sophisticated organization. B. label paper or ribbon poor uneven surface, which is caused by one of the main cause of the print head broken. C. typically use poor quality labels or ribbon need to increase the temperature of the print head to print clearly established as 214 yards machine, and high temperatures tend to be easy to break and cause the print head to shorten the print head life of reasons. D. falling on the ground of label paper, has been covered with dust but rewind back to use. E. Use ribbon width should be slightly wider than the labels because labels are very sharp edge will cut the print head, so do not use in order to save ribbon narrower than the size of the label sheet. F. print below the head of the rubber roller is not clean, there are many projections impurities cause the print head wear. G. In order to reduce the thermal print head is corrosion can usually be ethanol or IPA wipe the print head surface confetti and toner (remember not to touch the hand surface heating element); recommended without Na ions, K ion, Cl ions, and high reliability and evaluate good brand labels and ribbons; try to avoid making the surface of the heating element of water vapor. In case there is water vapor, set voltage is set to off, until the moisture disappears.
