Guide: Ribbon is the main consumable of the dot matrix printer. Here are some ways to save the ribbon. Other printers can also refer to it.
Prepare two print ribbon cartridges and print the official document in a darker (new) ribbon, using a lighter color (used, but the base must be intact, otherwise the needle will be damaged) Ribbon prints an informal paper or wax paper.
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 and prolong The time the ribbon is used.
Use two foams with better quality printing ink to hold the ribbon exposed at the front of the ribbon cassette, then gently rotate the ribbon shaft to add some ribbons that have been used for a while (with the base intact) 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 informal page spreads the ink evenly and prints the official draft.
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.
The ribbon can be removed 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.
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 "hole". At this time, the ribbon cassette should be opened first to check whether the gear and the metal card are in series (mostly 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 the thin line in the left and right direction at the upper and lower interfaces. Needle (usually only the middle section of the ribbon). 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.
