The Rest of My Life is Expensive, Please Get to Know Me Again- Print Head

Today we will introduce the structure of the print head and the related knowledge to help you know print head again.

The structure

The large format printer is an electromechanical device that combines both fine mechanical structures and complex electronic circuits.

There are precise printheads in the mechanical part.And when it comes to the structure of the printhead of the printer, many friends will think of words such as mystery, high technology, etc. In fact, distinguishing it from his structure is not complex. Here we take the Z5200. As an example of the printhead, to uncover its mysterious veil.

1.Component parts

The printhead is mainly composed of the following four parts: cavity, ink inlet, air bag, and seal ring.

2.Each part function

Cavity: used to store ink, at the bottom of which there is a layer of filter that can filter a small amount of impurities out of the nozzle.

Ink port: The only channel for ink to enter the chamber.

Airbag: Adjust the pressure in the print head through the expansion or contraction of the airbag to ensure the normal ink output.

Sealing ring: plays a role in sealing, to ensure that the printhead does not leak gas, no leakage of ink.

1.How the print head completes the ink jet process

Simply speaking, using a heated ink, the resistance in the print head heats the ink at a rate of more than 1,000,000°C/sec. Heating a layer of ink about 0.1 Micron thick in the wall to about 340°C to form a bubble and the bubble bursts. Then fire the ink to complete the ink jet process.

2.Print heads for precise imaging?

The printhead, the ink jet of the prior printer, the imaging work, he can place the color accurately at each point,

Print out the ever-changing images. In fact, the printhead wants to print a perfect image, which requires the common support of both data transmission and print head positioning.

To achieve the transmission of data,it need by means of electrical signals through the comparison of contacts and printhead contacts. The positioning of the print head is done through a grating inside the printer. Everyone knows that we can see the grating with the scale by opening the front cover of the machine.

3.How to print ink into the cavity?

The structure of the printhead is very precise. The inside of the print head is in a sealed state. By expanding or contracting the air bag, and changing the pressure inside it to in and out of the ink. That means that the ink needs to enter the cavity and the ink must flow out. Do expansion action). However, under normal circumstances, the airbag is in a contracted state. If inject ink from the ink inlet to the print head, the ink cannot enter because of the pressure. The pressure will change the ink smoothly only when inflating the airbag. Inflow, this needs inflating the airbag to achieve. This is why inflating the printhead at the same time when refilling the print head.

No matter which brand of printer is needed to replace the print head.If the manufacturer says his print head is not bad, then he must be lying.Our company offer print heads in a affordable price.If you have some demand,please feel free to contact us.

Print Head Installation And Testing Methods

Tags :

Category : Blog , Tips & Tricks

Print head is a part of the printer, firstly, printer installed new print head must to test. These are the test methods:

print head

1. Check Blocked

Before the print head trial, syringe needle water to check the print head to see if clogging. However, this is a very superfluous and dangerous practice. First of all, once the print head in the water, you do not have to dry it and turn on the power, ranging from burning plate to heavy burning head. Not only washed away the protective liquid in the head, but also because of the pressure of the hand is too large, easy to cause the nozzle air blockage, resulting in no ink.

2. Protect print head

Head of the print head is very fragile, absolutely can not bump, do protect it. Its surface is a piece of aluminum, the inner layer coated with a crystal oscillator and a very small ink tube. In fact, a touch will be concave, deformed, or even broken, so that the nozzle scrapped.

3. Installation

Be careful when installing print heads. At first, you should be sure to power down and put in place. After loading, gently push the car around, to test whether it is smooth, do not install it on the power. because if the head is not in place, the car easily move the head to the collision fragmentation, and the human hand feel, retractable , strong controllability.

4.Plug the cable

When print head plug the cable, do not bring ink. At the same time, you should to ensure good contact with the socket, do not touch the foot. Otherwise, it will cause the nozzle short circuit burned.

5. Keep steel shaft clean and smooth

The steel shaft should be clean and smooth. Certainly, it can be used to wipe the sticky point grease, do not refuel directly to the shaft. Otherwise, it also cause damage when the excess oil will flow to the print head up.

6. Check the cartridge

It is necessary to test the waterway after machinery, circuits are correct. First of all, look at the amount of ink within the ink enough. Second, check the small cleaning blade, ink pump is dirty.

7.Exhaust the air inside the print head

On the inside of the print head there will be air after installed , so it will not print properly, only the head of the air completely discharged after the normal altogether lines; specific steps are as follows:
First of all, intermittent cleaning (only 2 times at a time and then 2 times after cleaning for 30 minutes) can be repeatedly washed repeatedly to cause the cleaning pump to accumulate ink, which will not only make the printing mix and ink leak but also waste ink.
Second, you can print more pictures, let the nozzle discharge air in the work.
Last, if the machine has led to the waste ink tube, you can first power off, and then use a syringe to set a rubber tube to waste tube. In addition, until 3-5ML ink is drawn so far, and then start the machine, the normal cleaning with the machine, it is equal to Artificially to the head of the air to hard out, the side effects are likely to cause the pump to heap ink.
