How to repair the nozzle blockage of the small character inkjet printer?

The nozzle of the cij printer has an automatic cleaning function, which will not cause the nozzle to block under normal use. However, in these cases, it may cause the nozzle to block.

If the machine is left for a long time without causing the ink to dry and block the nozzle

The poor working environment caused excessive impurities and blockages in the pipeline

No nozzle cleaning was performed when the machine was turned off

Ink consumables for inkjet printers are generally quick-drying, and some are pigment-based, and the pigments are easy to settle, so the nozzles are more likely to be clogged. The key to the small character inkjet printer

The part is the nozzle, and the nozzle is the most prone to problems with the nozzle. Although some cij printers have automatic cleaning functions, there are also many external factors that make it impossible to fundamentally eliminate nozzle clogging. The following editor briefly introduces the nozzle clogging of the two small character inkjet printers and the treatment methods.

1. There are ink lines, but the ink lines are very off-set, and they may be in different positions each time.

We can first try to operate directly on the machine, and open the nozzle by exhausting, flushing, and repeatedly opening and closing the nozzle. This method is very useful in most cases, so it saves the trouble of removing and cleaning the nozzle. If it doesn't work, only remove and wash the nozzle.

Second, there is no ink line at all. Need to disassemble and clean the nozzle, the specific cleaning method is as follows: 1. Prepare about half a bottle of cleaning liquid. Put the nozzle into the cleaning fluid bottle, close the lid and shake it vigorously. Usually it is done after 5-6 minutes.

2. If it is not successful. Continue to soak for about 10 minutes, and then shake it again.

3. If you haven’t succeeded, you can check whether there are any small things stuck on both sides of the nozzle. You can use a fine needle to pick up the foreign matter attached to the nozzle. Then go to shake the bottle

sub. This is basically done.

4. If it is still not good, you can use dilute acid (preferably dilute hydrochloric acid) to soak for about 3 minutes, generally it can be resolved.

5. If it is still not resolved, add cleaning fluid to the beaker of the nozzle house, and fill an appropriate amount of water in the ultrasonic oscillator. Put the beaker in the water, it is best to make the bottom of the beaker contact with the bottom of the ultrasonic wave instead of floating on the water. The problem is generally solved by turning on the ultrasonic vibration for 10 minutes.
