How to detect if the piezoelectric photo machine nozzle is damaged
When we are using a piezoelectric photo machine, how should we do a good job of checking and judging the nozzle if the nozzle cannot be discharged or the quality of the nozzle is not good? Everyone knows that the nozzle is the core of the photo machine. Its price is also an important part of the price of the photo machine. In the fault detection of the photo machine nozzle, you should know the correct check and the damage of the nozzle. Do not blindly replace it. Nozzle.
The detection technique of the piezoelectric photo machine nozzle printing without ink failure:
1. The photo machine prints with broken lines, printed horizontal stripes, color cast, and some colors cannot be printed. Most of them are faults of the ink supply system, not the nozzles are blocked. First check the ink supply system of the photo machine, such as ink cartridges, ink tubes, ink bags, and ink capacity. First check if the ink in the ink cartridge is insufficient, whether the ink tube is leaking or broken; in addition, check if the ink bag is damaged. If there is no problem with the photo machine accessories, the user can use the ink pump and the cleaning nozzle that comes with the photo machine to clean it two or three times, then print the test strip to see if the printing is normal.
2. Excluding the fault effect of the above ink supply system and the no-effect of the nozzle cleaning operation, the nozzle prints still does not discharge ink or lacks a certain color. At this time, the nozzle can be manually vacuumed and the nozzle is damaged. The method is as follows: first remove the nozzle, be careful when removing the nozzle, and do not scratch the surface of the nozzle. Use a syringe to draw about 40ml of special cleaning solution, and inject it from the ink supply tube interface on the upper part of the nozzle. Pay attention to the status of the water line sprayed from the nozzle. If all the water lines are straight, it means the cleaning is effective. This nozzle can continue. Use (Note: the premise is that the circuit and the piezoelectric crystal are all intact.) If the manual ink cleaning can not be solved, you can use the soaking method to solve the nozzle blockage fault, pour a proper amount of special cleaning solution into a clean glass container to put It is advisable to submerge the bottom of the nozzle 2 to 3 mm after the nozzle, and then seal the glass container (anti-ash) with plastic wrap for more than 1 day. Be careful not to touch the cleaning fluid at the signal interface at the top of the nozzle, as this will damage the nozzle.
3. The above cleaning operation for the nozzle without ink discharge can still be solved. Basically, it can be judged that the nozzle is damaged. At this time, the nozzle needs to be replaced.
For the use of daily photo machine, the problem of the blockage of the piezoelectric photo machine nozzle is mainly "prevention". The correct operation of the photo machine must be paid attention to. The operation of the photo machine nozzle is normal. The sprinklers do some proper and effective daily maintenance and maintenance, which will greatly reduce the possibility of nozzle blockage. In addition, Lecai domestic photo machine equipment is not only cost-effective, stable operation, low maintenance cost, long service life, ultra-fast printing speed and high processing precision. Lecai domestic photo machine value-for-money performance, an important manifestation of product quality and service, can make more users willing to choose music photo machine.
