Summary when we use the bar code printer is more or less there will be some big and small problems, this is unavoidable, the cause of the problem may be the human improper operation, or the quality problem of the machine, the material itself, bar code printer failure would be the delay of our time. So how to fast and efficient when we use the bar code printer can appear more or less some greatly small problems, this is unavoidable, the cause of the problem may be the human improper operation, or the quality problem of the machine, the material itself, bar code printer failure would be the delay of our time. So how to fast and efficient to solve the problem of the fault the bar code printer, make our bar code printer function back to normal work as soon as possible, is that we must learned skills. So now I will simply one of the most common fault for us the bar code printer & ndash; — Bar code printer to print the carbon with fracture, how to eliminate the phenomenon. Appear this kind of problem in general because of improper barcode printer setup. Because the bar code printer to print set too high a temperature or depth, at the same time, bar code printer out of paper or printing speed and Settings, slowly to the carbon with by too much heat, when the print head caused by carbon film is the phenomenon of break. When this happens we will reduce some appropriate temperature or depth, or some printing speed moderate increase. Print speed, depth of the print and print temperature need reasonable configuration, reasonable collocation, to achieve the best effect of printing. This not only can make the barcode printer to work properly, but also can effectively protect the print head, so the bar code printer may wish to test a few times more before formal work, in order to find the best configuration, let us bar code printer can work more stable for a long time. The other carbon belt quality problem is also one of the cause of fracture, carbon took place a long time, place where the air is dry, can easily break.
