in the use of bar code printers, bar code printer is more or less there will be a little bit small fault, whenever a failure will greatly affect our work efficiency, sharing of today is: barcode printers, common failures, along with the solution! 1, undetectable paper when printed. Reasons: 1) Sensor (2) Label paper. Solution: you can change another kind of paper label print, look to whether normal, if normal, print a few protracted war in just can't measure up to the label of paper, to test the paper printing. Such as is not normal, first clean the dirt on the surface of the sensor, if not only replace the sensor test paper again. 2, when the printing is clear, while the fuzzy. Reason: the printer pressure imbalance. Solution: the print head screw knob are adjustable pressure, the print is not clear that one side pressure adjustable bigger is ok. In addition some machines with only one screw knob adjustment, but can move freely, then put it into is not clear that a move to increase pressure with respect to OK. 3, always keep the tag changes when not, according to save there is a warning dialog box, according to the software after shut down. Reason: the user modify directly on the label changes caused by wrong operation. Solution: you can change the modify according to the right way to modify the double-click to modify content, you write when the original layout dialog box on the modification, are not allowed to directly modify label on. This modified is back to normal. 4, small printer in the print label will not reach the designated position, total slants upwards or downwards partial printing content. Reason: the tag is too small, sensors are difficult to sensor to the paper. Solution: general label high at least more than 10 more than just good positioning, otherwise will be to offset Settings TAB. In the tag set, the label set to higher than the actual label tall a 5 mm or so, and then according to the specific migration situation to offset Settings TAB. 5, when printing labels, there are always some words can't print it out. Reason: the print head is dirty, layout is wrong. Solution: cleaning the print head; In addition whether in typesetting to overlap the printed word, recomposition. 6, printer when printing always shows no paper or carbon belt. Reason: you run out of paper or carbon belt is wrong; Solution: send the wrong operation command. Check the paper or carbon belt is correct; Parameters set on the machine, then use printing software for printing after the correct layout Settings. 7 when printing, printing is not clear, the ribbon is broken. Reason: printer carbon belt shaft failure. Solution: carbon belt machine shaft tension is too tight, adjust printer carbon belt shaft under tension. 8, the new file can be normal print, but can't open the old file, unable to print. Reason: network printing, permissions error. Solution: print, whether on the Internet has opened this file, if you open, must first turn off can be opened on another computer. Then detect network access problems. 9, print content when the print is not completely. Reason: printing software and driver version is too low. Solution: install the new version of the barcode software and drivers. 10, barcode software cannot be typography. Reason: the software not installed or computer problems. Solution: to install the software, if not yet, may be computer got a virus and anti-virus, please. Not again, please reinstall the operating system.
