Summary of bar code is widely used to promote the fire bar code printer, and as one of the core application part of the printer, the print head while accept high strength work, the print head loss also become very bad, for the daily maintenance of the print head has become a big problem every customer, a change not only the price of the print head barcode widely used the fires of bar code printers, and as one of the core application part of the printer, the print head while accept high strength work, the print head loss also become very bad, for the daily maintenance of the print head has become a big problem every customer, a change not only the price of the print head cost is high, can also affect the work efficiency, so we in the daily use barcode printing equipment, you need to do scientific maintenance of prolonging life, especially the print head of maintenance, is Paramount, so how to maintain barcode printing head? First to learn about the causes of bar code printers, print head damage factors. When talking about the print head daily maintenance, we need to learn about the causes of damage of the print head factors have? Bruises, long-term mobile printer head can lead to labels, ribbon ceramic coating layer of wear and tear, let the print head pin exposed, resulting in damage, this also is the main cause of the damage of the print head, cuts the damage, can prolong the service life of the print head. 1, when used in printer, as far as possible to reduce the print head pressure and temperature produced by printing 2, to ensure that the width of the ribbon and label, prevent the exposure of the print head labels appear abrasion phenomenon often 3, remove the print head by accumulation of garbage, use the print head film can quickly and easily remove 4, ribbon back layer of dirty problem, with the back layer of protection of thermal transfer ribbon, the ribbon need to consult non-viscous ribbon, with scattered electrostatic and lubrication effect. So, how to proceed the print head of maintenance? Remove dust regularly first: many users aware of barcode printer print head scratches will make its damage, so avoid more, but I don't know the dust can also affect life, daily in the dust removal for bar code printers, regularly to prevent pollutants concentration result in heat transfer problems and cause severe burn needle. Second: avoid high temperature scrubbing barcode printers print head normally need to use alcohol regularly to clean, but just the printing is completed, the fuselage and the print head still have high temperature, do not use alcohol to clean at this time, it will make the print head wear aging, sharply to stay the whole machine body cooling after cleaning the print head again, make sure that the print head without high temperature before wiping. Third: using the standard carrier in daily in addition to outside the bar code printer wipe the dust on a regular basis, at the same time should be used in the daily standard printed carrier, such as: try to use dry wet paper for printing, if the paper is uneven, also may make the printer print head is broken needle, or wear reduce its life for a long time. Fourth: do not make external shocks in daily use bar code printer, the external force from contact with the bar code printer, especially for the print head is relatively weak, in a try not to human intervention when necessary, external shocks is easy to make the print head is damaged, should avoid as far as possible. Small make up remind: because the barcode printing head is consumables, daily abrasion and wear of inevitable, but if you can pay attention to the above points, for its science and maintenance, then can make the life of the print head is greatly increased. Except to maintain the print head, still need to fuselage chassis and other scientific maintenance, prevent get damp deformation, external force damage.
