Summary to say the most valuable parts of a bar code printer, it must belong to the print head. The print head is important but it is also the most vulnerable and most people want to know the bar code printer print head general service life is long, for that matter, but can't use the time to calculate accurately, but according to print to say the most valuable parts of a bar code printer, it must belong to the print head. The print head is important but it is also the most vulnerable and most people want to know the bar code printer print head general service life is long, for that matter, actually can't use the time to calculate accurately, but according to the length of print. But everyone should know that any thing to use for a long time there will be wear and tear, it still depends on everyone's efforts in a maintenance and values. Zhuhai jia bo below barcode printers print head will appear to you talk about problems and some preventive measures. A, bar code printers, the print head life of general how long? Basically barcode printers, the print head life is not the length of time to calculate. But in print length is calculated, a bit like a car mileage. General printing header the normal service life of about 30 km ~ 50 km, that how many labels can be printed? For example: the tag high 3 cm = 1. 66 million thousand, but printhead is also need maintenance care like car engines, and the most direct harm printhead, shorten printhead life is labels, carbon belt. Because the material is direct contact with the printhead, like automobile gasoline. So the quality requirements for materials, can not only in price evaluation. Otherwise because of cheap label hurt expensive printhead that thed loss outweights the gain. Second, the bar code printers, print head appear breakage is what reason? Bar code printing head is made up by a row of hot hot needle, and the higher the density of printhead hot needle is fine. So the print head is broken needle phenomenon is easy to see, if you find the label print out from top to bottom has a straight, fixed line blank, means printing header broken needle, needle breakage and printed header is beyond repair, can only be replaced, and the price is not cheap, it is very important to take good care of. Three, the main factors of print breakage is which a few? 1. Inferior surface of the label contains uneven phenomenon, is also one of the main original cause breakage. 2. Paper on the surface of the dust, like a big stone as scraping the thin needles. 3. Due to the use of low-quality carbon belt and tag and header temperature must be raised seal, can print clearly, but high temperature is also easy to breakage and printed header shortened lifespan. 4. Fall on the ground, dusty and back roll back already use. 5. The use of carbon belt width should be wider than label, because the edge of the label is very sharp; Not only will cut the hand will cut printhead, so don't to save carbon belt and use than the size of the label narrow; Then in the cost of the printhead is saved. 6. The print head below the cylinder is not clean; There are many prominent hard rubber piece of dian lame pavement. Four, bar code printers, the print head should be how to maintain? 1. Try to use label and bar code printer agents provided carbon belt. Because at least they better understand the features of the printer, more can understand the importance of the print head and expensive. 2. Don't will have to drop on the ground covered with dust or no packaging good label computer use. 3. Don't go to adjust in order to make the black point temperature printhead, as long as the clear printing. 4. The level of the bar code printing head vertical pressure to give an accurate and won't cause burden uneven phenomenon and breakage. 5. Each with three volumes of carbon belt with cotton buds dipped in alcohol to wipe the barcode printer head, with a clean cloth to clean oil stains will drum, reoccupy brush the dust within the mechanical. Is zhuhai jia bo above barcode printers print head will appear to you talk about problems and introduces some preventive measures, in fact, whether the print head or printer, we all should well maintenance good, so you can play a bigger role in the process of its run.
