Ribbon and printing paper

The printing output of the printer is inseparable from the printing ribbon and printing paper. In the application of computer system, printing paper is the most common consumable, followed by printing color

Printer ribbons have been produced and used by rats for a long time. For example, electronic products such as teletypewriter, wide line printer with word wheel and wide line printer with steel strip are all used with ribbon. However, the needle printer with the most glue is the needle printer matched with Hui machine. At present, gb43 i3 has been issued by China- General technical requirements of woven printing ribbon for office machines and printers for information processing. It is taut and plump, and the tomb is clear and flat. The edge of the belt is straight and the light is not slanting. The color belt is not ragged and fluffy. When printing, the handwriting is clear and the ink is not seeping. When it comes to water, the characters will not melt or disperse and wear well. It has the advantages of good beating resistance, strong color ratio, non staining of the paper, excellent transfer performance, high speed when used as reel, and greatly improved service life when used as closed-loop ribbon. It is required that the fracture strength of the closed-loop joint should meet the relevant standards of gr4313 (the tensile force of U-belt joint is generally about 3.5 kg, and that of mesh production Ribbon joint can be as high as 4.5-5 kg), The width of ribbon should be selected strictly according to the regulations of printer. The national standard gb3261 (width of braided printing ribbon used in office machines and printers for cleaning and information processing) has been promulgated by the state. 12.7 mm || 13.0 mm should be selected in 24 point matrix Chinese character printers The material of the ribbon is not the same. Synthetic fiber is generally used for the ribbon of cotton, silk or synthetic fiber. For example, nylon Doyu spinning is used as the ribbon base. The color of the ribbon can be monochrome, bicolor or polychromatic. In the computer system, black is the most commonly used, while two-color and multi-color are seldom used. The service life of the printer is related to the performance of the printer. Generally, ordinary printers use ribbon under normal conditions. Its life span is one million characters. For example, th3070 24 pin Chinese character printer 2, its ribbon life is. 500000 characters. The service life of nm-5020 24 pin Chinese character printer can reach 5 million characters. From the experience of printer design and maintenance, it can be seen that the reasonable use and replacement of color bands have a great relationship to ensure the printing quality and reduce the wear of print head and the fracture of printing needle. The color bands that do not meet the requirements or have been found to have defects can not be used reluctantly, even if the part with small size should be used Otherwise, it may lead to a huge drop in the print head.

The printer working in harsh environment. Put forward more stringent requirements on the ribbon. Because of the high temperature environment. Ribbon oil. Easy to dry operation. Tape copy easy to aging and deterioration; Under the low temperature, the oil solidifies and becomes brittle. Each needle is hit on the ribbon like a knife, which causes the ribbon to break. When printing under the low temperature, it is easy to wipe the vivid handwriting and the color is thick, while the writing color is light under the low temperature. After repeated tests, it is considered that the imported nylon ribbon can be used in low temperature (- 20 degrees).
