Printers are the most commonly used equipment in daily business. Many people don't understand the impact of printer ribbons on human health. In fact, some non-original ribbon raw materials contain harmful substances such as lead, cadmium and mercury, which are harmful to health.
The most important factor in determining the print quality and life of a dot matrix printer is the quality of the print ribbon, which can be worn out with a compatible ribbon or excessive use of the ribbon. However, many people choose non-original ribbons to save more than ten yuan, but I don't know that this will cause more loss to the print head and easy to break the needle, which will not only shorten the service life of the printer, but also increase the overall cost. In general, on average, every 30 compatible ribbons wear a printhead.
Compatible ribbons often appear to be full of ink, and the ribbons are sticky when in contact with each other. People who don't know will think that such a ribbon will print better. It is not known that such a ribbon is actually relatively large in ink particles, and the ink is not degreased. When such a ribbon is used for printing, the color density will appear, and when it is touched by hand, it will be blurred, and the ink particles will block the print head, causing the printer to malfunction. Over time, the durability of the printhead will be affected and the printer will be prone to malfunction.
The working principle of the dot matrix printer is to use the dot matrix striker in the print head to hit the print ribbon to produce a printing effect on the print medium. Thus, the consumption of the ribbon in this process is very large. Many people know that ribbons only affect the print quality, but they don't know the quality of the ribbon has a very important impact on the life of the print needle and printer.
