Print pin life

Because the bill printer creates a small point by printing the impact on the ribbon, so that the final imaging, the print needle will inevitably produce wear, to a certain extent, it can no longer be used. The lifetime of a print needle refers to the number of times that a print needle can be hit before it is decommissioned. Its unit is "Hit/needle ".

At present, the life of the print needle of the product can reach 0.2 billion times of hitting/needle, and some even more, can reach 0.5 billion times of hitting/needle. However, there are two issues to note. First, because the frequency of each print needle on the print head is not the same, it is certain that some needles will be decommissioned first, and some will be decommissioned later. The other point is that "hundreds of millions of hits/needles" is an approximate number. To know such a large number, users cannot actually perform detection and computation. Therefore, it is important to pay attention to the free warranty period of the print header during purchase.
