Inkjet printer, as a commonly used printing equipment on the production line, is widely adopted in food, medicine, daily chemical, label printing, card making, packaging printing, medical, electronics, hardware and other industries. It needs regular maintenance, otherwise it will increase the probability of inkjet printer failure, causing the inconvenience and loss to the factory.   How to maintain the CIJ printer?  We can pay attention to the following aspects: 1. Ink—check the liquid level of ink, solvent and ink viscosity every day to see if it is normal. When the ink level is too low, it must be added in time, but be careful not to the adding amount. If the ink is too full, precipitation will easily occur, which will affect the quality of printing.Ink viscosity is related to whether the inkjet printer can run stably or not.High viscosity will increase the load of the main pump and cause damage to the motor diaphragm; low viscosity will easily cause the pressure pump to rotate at high speed, which will shorten the life of the pump! In addition, if the viscosity of the ink is too different from the set value, it will also affect the printing quality of the product.   2. Nozzle - Clean and dry the nozzle before daily use. As a key part of the inkjet printer, if the nozzle is too dirty, it will lead to abnormal charging and large voltage changes at the deflector, which will directly affect the printing quality. Therefore, when you find that the nozzle of the machine is too dirty, you should scrub it in time, and dry the nozzle with a hair dryer after cleaning.   3. Hygiene—clean the inkjet printer and its surroundings daily, clean the filter screen and check the fan every week, and replace the main filter regularly. Keep the shell of the inkjet printer clean and hygienic, without ink stains. If there are dirt and debris, it needs to be cleaned up in time. This can better protect the shell of the inkjet printer and prevent corrosion caused by ink dripping on the surface of the shell. It can extend the life of the equipment.  In addition, regular cleaning can allow the air inside the machine to circulate more smoothly and prevent dust from entering the circuit system, so as to ensure that the temperature of the circuit system is always kept at normal temperature.  4. Placement and movement - it is strictly forbidden to move randomly and place more than two inkjet printers on the same production line. If there is a need for production, another inkjet printer with different ink colors can be placed. When the inkjet printer breaks down,you need to contact  the maintenance personnel immediately to solve the problem. At this time, the machines on other production lines should not be moved at will. If necessary, pls. obtain the consent of the maintenance personnel at first. In addition, when handling the inkjet printer, we must pay attention to prevent excessive vibration, handle it with care, so as not to damage the inkjet printer due to negligent handling. 5. Shut down and restarted - after shutting down for more than 72 hours and then restarting, the nozzle is clogged. This situation often happens. At this time, just remove the nozzle and clean it, then dry it with a hair dryer and install it back.  If you encounter situations such as small holidays that need to stop for more than 72 hours, you can release the ink in the inkjet printer (especially the white ink machine) and input a solvent for maintenance. In this way, it can prevent the ink from settling due to long-term storage, and reduce the damage to the machine caused by human negligence. Industrial identification equipment is divided into purchase cost and use cost. The purchase cost is the price of the equipment. The cost of use is not only consumables, but also accessories and after-sales maintenance fees. The most important thing that is easily overlooked is the increase in costs caused by the shutdown of industrial marking equipment. The stoppage of production is not only the loss of orders cannot be delivered to customers in time, but also the waste of raw materials and the increase cost of the whole production line. Therefore,the stability of the production environment should be considered firstly.
