Guangzhou State Association Zebra bar code, bar code machines wholesale zebra, zebra bar code provided by the Guangzhou State Association. We are Guangzhou City State Association Information Technology Co., Ltd. (www.gzdb899.com) located: Guangzhou specializes in: cash register, scanner, bar code machines, management software, small ticket machines, cash registers, bar code printers shredders Market Status: Currently, due to the printer with the decline in domestic prices, has begun to spread, in foreign countries, almost all of the production units are equipped with a bar code label printers (ie LABELPRINTER and BARCODEPRINTER), in terms of product identification and other applications, and Most companies have a barcode reader (ie SCANNER) and bar code data collection (of inventory) ancillary equipment such as printers, forming a company's internal management barcode management automation management. Now, we are here to briefly explain the situation in the country barcode printers. 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. Usually break the print head can not be repaired, only to 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 for Zebra bar code machines wholesale, small dust like a big stone scratching delicate tissue. 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 clear, and the high temperature is often the cause of the print head is easy to break and shorten the life of the print head. 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 Zebra barcode label paper machine, because a very sharp edge labels will cut the print head zebra barcode Which is good, so do not use in order to save ribbon narrower than labels size. F. print below the head of the rubber roller is not clean Zebra bar code machine suppliers, 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.
