1. Pay attention to the power of the printer.
Printers, like many computer devices, are also very afraid of strong magnetic fields. Therefore, when using the printer, try to avoid using the same multi-function power socket with high-power capacitive or inductive appliances, and keep the position away from these appliances (such as There are high-power motors DJONZMYOJQIZIWBGKJPY motives, etc.).
2. Pay attention to the environment in which the printer is placed.
The working environment of the dot matrix printer should be as clean as possible and the dust should be kept as little as possible, and it must be kept away from the acid and alkali corrosive items. The workbench on which the printer is placed must be stable and vibration-free, especially if it is not on the printer. Place any items so that they do not fall into the machine and affect the operation of the mechanical parts, or even cause serious problems!
3. Regularly clean and strengthen the lubrication of the printer.
The printer is a mechanical product, so we often use a small brush and a "skin tiger" to sweep and blow off the paper dust and dust scattered inside the printer, and also keep the appearance of the printer clean, dust and smudge should be wiped in time Beyond to avoid entering the inside of the printer in the future, especially the guide axle and all transmission gear systems should be kept clean and free of dust. You can gently wipe the carriage guide shaft with a soft cotton gauze or gauze cover. Add a small amount of medium and high-grade lubricants. If the guide shaft of the car is too dirty, it is easy to make the car move poorly. In this case, if the working time is slightly longer, the car drive circuit may be heated to burn out.
4. Replace the print ribbon in time.
After the printer's ribbon is used for a period of time, its color will become lighter. Remember to change the ribbon in time. Try not to adjust the stitch length or increase the printing. This will easily cause the broken needle. Of course, you It is best not to use the old ribbon that has been recolored, because most of the old ribbons have already been raised, and the textile density has already been destroyed. Therefore, it is easy to block the printing needle guide holes after using the old oil ribbon with heavy oil. The author advises you not to cause unnecessary troubles for the greed of the moment. In addition, when some parts of the ribbon are unloaded, they should be replaced in time to avoid hanging up the print needle. Note: I strongly recommend that you must replace the ribbon with good quality, and try to buy it from a reputable merchant. The author will not say more.
5. Be sure to properly adjust the gap between the print head and the print roll.
Almost all dot matrix printers have a switch that adjusts the paper thickness. When we print different layers of paper, we must choose the appropriate adjustment lever position. For example, when we want to print a layer of paper, the adjustment lever should be placed at 1 or In the position of 2, when we want to print 2 layers of paper, the adjustment lever should be placed in the position of 2 or 3. The authors of this kind are not listed one by one. The specific position of the adjustment lever should be set according to the printer operation manual. Just follow the principle of Ning Yuan, and for new printers or new print heads, it is better to adjust the paper thickness switch to a larger size because the new print head and print pin have not been worn. The paper thickness switch is placed in the 3rd or 4th position. After the printer has been used for a while, slowly put the switch in the proper position.
