The core component of a digital printer is the nozzle. Regarding the correct and effective nozzle cleaning of digital printing equipment, many customers and friends are not very clear or the method is improper. This article analyzes the correct method of cleaning the nozzles of industrial corrugated digital printers, and hopes to be helpful to customers and friends!

Cleaning the nozzle of the digital printer is a very important technical activity in the maintenance of the digital printer. Correctly mastering the cleaning method of the nozzle can maintain the nozzle of the digital printer well, effectively prolong the service life of the nozzle, and reduce the depreciation cost of the equipment.

The most common ways to clean the nozzles of printer nozzles:

The first method: soaking method

Scope of application: light obstruction, necessary tools: 95% alcohol, a clean cup and a metal container with a smooth bottom.

Prepare a small flat plate, place the nozzle flat on the plate, and then inject the universal printer special cleaning solution into the plate, the depth is based on the part of the nozzle that has just been submerged. Be careful not to splash water on the cable plug and the driver circuit board, the first soaking time is about 1 to 4 hours.

The second method: nozzle pressure flushing, scope of application: severe obstruction.

Necessary tools: 95% alcohol, a clean cup, a disposable syringe, and a disposable infusion set.

Working principle: Use the pressure generated by the siphon action of the syringe to inject alcohol, an organic solvent, into the print head, so as to clean the dry ink head.

Use a plastic tube of a disposable infusion set, insert one end into the 5ml syringe, and insert the other end into the ink inlet hole of the nozzle that needs to be flushed, press the distilled water in the syringe into the nozzle, pay attention to the pressure not too high, so as not to squeeze the water Waterproof isolation glue inside the bad nozzle. This process needs to be repeated many times until you see a thin water column ejected from each ink outlet hole. In this way, the clogged nozzle is cleaned and dredged.

The third method: distilled water cleaning method. Scope of application: severe obstruction

Necessary tools: a decoded empty ink cartridge, a disposable syringe and a bottle of medical distilled water (purified water can also be used instead).

Working principle: It is similar to the working principle of the pressure cleaning method, so there is no need to go into details here.

Solution: Prepare an decoded empty ink cartridge, a disposable syringe and a bottle of medical distilled water first, use the pressure generated by the siphon action of the syringe, suck the distilled water into the cartridge through the vent hole of the syringe, and inject it into the cartridge after a while. Use a syringe to suck out the injected distilled water, so that the remaining ink in the ink cartridge can be cleaned repeatedly.

The fourth method: Ultrasonic instrument cleaning method, scope of application: the most serious obstruction

Working principle: The ultrasonic cleaning machine is used to generate strong ultrasonic waves, which makes the water molecules vibrate violently, and dissolves the fine dry ink particles in water, so as to achieve the purpose of cleaning.

Solution: Gently put the inkjet print head into the cleaning machine, add pure water or special print head cleaning solution, the pure water or special print head cleaning liquid should cover the stainless steel edge of the print head, and turn on the machine for 10 to 15 hours It can be quickly cleaned. The advantage is that the cleaning effect is very ideal, and the print head that has been blocked for many years can be cleaned, and the operation is very simple; the disadvantage is that the maintenance cost is high, the price is relatively expensive, and frequent use will cause fatal damage to the inkjet print head that is difficult to repair.
