In the daily use and maintenance of the printing machine, it is also a very important work to recognize and replace general parts, such as common vulnerable parts, cap station, ink damper, etc. you can learn by reference, pay attention to such problems, which will be helpful for the maintenance of the printing machine in the later stage.
1. Cap station:
The Cap station is also called the ink stack core. It is located directly below the printhead of the photo machine and on the right side of the whole machine. It is mainly used to protect the printhead. Its main function is to suck out the residual ink in the print head hole and avoid the phenomenon of dry plugging caused by solvent evaporation and drying.
According to the movement mode, the cap station assembly can be divided into slider and lifting. Generally speaking, the lifting ink stack cleaning printhead is more thorough and has better effect, so it is more suitable for application. But combined with the actual situation of the domestic market, the slider mode is still well used in the domestic photo machine. Ink pad, ink stack and so on are combined to form the automatic cleaning and moisturizing function of the print head.
2. Ink damper:
What is a realistic ink damper? Where is it installed? Generally, the piezoelectric machine only has ink damper. A small plastic bag is located above the print head. When the ink pipe is connected with the printhead, you can see it when you open the printhead cover. It is one color, generally no more than 5cmx5cm. There is half a bag of ink in the transparent. It is connected with the printhead and the ink pipe. There is a filter screen in the ink damper, which can filter out the impurities in the ink, ensure the smooth ink supply, and prevent the printhead from blocking Plug, broken wire and other faults play the role of ink filtering. It is used to balance the ink pressure of the nozzle and filter impurities, as well as to "collect" the air in the ink path, so as to reduce the probability of printhead plug or increase the probability of printhead "plug".
The photo machine has been used for a long time. You will notice that there are too many impurities in the ink damper, the filter of the ink damper is blocked, and the ink breaks during the drawing. For such small faults, the manufacturer generally recommends replacing the ink bag. For the replacement of ink bag, the price is usually not expensive, usually tens of yuan can be purchased (it is recommended to use the ink bag recommended by the manufacturer or the original ink bag produced by the manufacturer for better effect)
