1, do it yourself
In fact, it is not too difficult to replace the printing ribbon by yourself. However, the different types of dot matrix printers have different ribbon frames. Fortunately, their ribbons operate in much the same way. First, open the top cover of the printer and you will see a black box (usually black) shaped like a clip. We call it a print stand, and the empty part of it is the print head. Remove the print carriage. Be careful to remove it from the end near the print head when unpacking. The print carriage can be easily removed. Then you can open the print carriage. Since the printer frame of different models is different in structure, its ribbon winding method is slightly different, so you must observe the winding of the original ribbon, otherwise the ribbon is very likely. Cannot rotate normally and cause printing to fail. It is necessary to pay attention to the two gears in the printing frame to be colored with the coloring tape, and should be parallel with them, otherwise it will cause the ribbon to shift with the rotation of the gear, and finally the gear can not be rotated. After the ribbon is installed, the print carriage can be returned to its original position and the ribbon replacement program can be completed.
2, a good way to extend the needle ribbon
In fact, as just mentioned, the ribbon is the main consumable of the dot matrix printer, then we have no way to extend the life of the ribbon in daily use, the answer is yes.
1) Prepare two print ribbon cartridges and print the official document with a darker (newly changed) ribbon. Use a lighter color (used, but the base must be intact, otherwise it will damage the needle) ) The ribbon prints an informal paper or wax paper.
2) Fix two small pieces of foam with transparent tape in the ribbon exit position of the ribbon cassette, sandwich the ribbon between the two foams, and let the foam absorb some good quality printing ink, so as to keep the ribbon moist. , extend the use of the ribbon.
3) Using two foams with good quality printing ink, hold a strip of ribbon exposed at the front of the ribbon cassette, gently rotate the ribbon shaft, and add some ribbons that have been used for a while (with a good base). Ink (the whole ribbon should be added, otherwise the color will be different when printing), then open the ribbon box and let the inked ribbon cool (or add a small amount of gasoline in the ink). Try it first. The page informally distributes the ink evenly. Print the official draft again.
4) Develop the habit of adjusting the distance between the print head and the paper according to the thickness of the paper. The principle is that it can be large and large, as long as the printing effect is satisfactory. For new ribbons, you can also adjust the distance when printing thin paper, because the color is thicker to ensure print quality.
5) Remove the ribbon when printing wax paper. At this time, do not directly print the wax paper to prevent the wax from melting into the pinhole. Most wax papers are provided with transparent paper, which can be printed on wax paper.
6) Sometimes the print ribbon cassette is not working properly, and the print pin repeatedly prints a certain part of the ribbon, causing the color to have a “holeâ€. At this time, the ribbon cassette should be opened first to check whether the gear and the metal card appear in series (large Part of it is caused by the card card is too loose). For the damaged ribbon, the hole portion can be cut off and then "welded". The welding method is simple: align the interface and slightly overlap, and stick it with a transparent thin tape on the inside (note: on the inside). If you are afraid of breaking, you can use a thin needle in the left and right direction at the upper and lower interfaces. The general ribbon only uses the middle section). According to the quality of the ribbon and the specific conditions after printing, I have adopted the above method, which usually increases the usage time of one ribbon by 1.5 to 2.5 times, which greatly reduces the consumption of the ribbon.
