Why Your Inkjet Printer’s Print Head Always Blocked?

As you know inkjet printers are a better choice for users who use less. They can print color at a cheap price, but the printing speed will be slower than that of laser printers. The faults that inkjet printers are more prone to are generally unclear printing and nozzle blockage.

If you don’t clean well, you can only change the nozzle. Anyone who knows the price of the inkjet printer’s nozzle knows that if you buy one separately, you can buy a new printer at the same price. Therefore, when the nozzle is blocked, it must be processed in time.

 

Why is the nozzle blocked?
Because the printer nozzle is normally sealed after printing and is not tightly sealed or placed for a long time, the water will evaporate excessively, causing the ink droplets to dry on the fine nozzle, so that the ink cannot be ejected normally; usually it is often broken, missing color, and handwriting. Fuzzy and other faults.

Cleaning and repair method: Software cleaning is cleaning using the print head cleaning function in the application tool of the printer driver. The advantage is that the operation is simple and fast; the disadvantage is that the cleaning effect is not ideal.

inkjet printerNote: 1 Do not mix ink. New inks can’t be rushed to add to the cartridge. First use a clean disposable syringe to inhale some of the ink and observe it in a bright place to see if there is any suspended matter in the ink.
2 cleaning methods should generally not exceed three times. When the printer is not clogged, it should be opened within three times.
3.Because of the “air resistance” phenomenon between the ink cartridge (such as the sponge filling type) and the print head, a small amount of irregular disconnection will occur. At this time, it is not necessary to repeatedly clean it. After being placed for a period of time, it can be used normally after restarting.

Why We Need Direct to Garment Printers (DTG)

The Direct to Garment printers, popularly known as DTG printers prints digital images sourced from a computer to a textile substrate. DTG printing is also known as inkjet to garment printing. A specially made inkjet printer is used for this purpose.

dtg A DTG printer offers a number of advantages as compared to traditional textile printing. Setup costs are much less, zero even, when compared to the screen printing method. DTG printers are essentially push button operations. You just have to start it and the machine is ready to do its work.

A big advantage of DTG printers are that it is perfect for small orders and the occasional print. Production costs are reasonable. Besides, any textile printing done through this technique are found to be detailed and accurate. Unlike their screen print brethren, the DTG printers does not charge as per colors printed. It follows that the printing is affordable too. The DTG printer inks attach to the fibers directly. The colors seem to be a part of the fabric. Simply put, this print technology is ideal for small quantity printing. It can also be used to print highly detailed images with gradients and shading. Various colors can be applied as well.

Process of DTG printers

The principal feature of the DTG process is that they are much simpler than anticipated. Many people are pleasantly surprised with the accurately rendered complex images on a fleece hoodie or a soft t-shirt. The DTG printer analogue is the home inkjet printers- with the exception of textile substrates substituting the paper. DTGs can be used to print a large variety of jobs, with millions of colors rendered.

The latest models of DTG printers are made specially for printing on textiles. They are formulated to print in a direct manner to the textile substrate. Other materials can also be used as substates. Most substates lend themselves to have photo-realistic designs on them.

DTG

DTG printing inks can be costlier compared to other inks. When it comes to darker garments, a white ink underbase is required below the design colors. This base layer makes sure that the colors appear the way they were intended.

Do note that DTG printers use minimum amount of ink. This puts costs incurred on ink supplies at par with technologies which use lower priced ink but in greater quantities. The RIP software used to print in DTG permits to put the perfect ink amount where needed.

Five Reasons for Burning Print Head of Digital Printing Machine

The digital printing machine print head can be used to print the best results, and the print head is good, and the ink will be more expressive. The print head is an indispensable carrier for digital printing production, but the operation is not good, the print head is easy to be burned, then everyone knows why the digital print print head is burnt?

There are five reasons why the digital printing machine print head is burnt:

1. The static electricity is too high

Excessive static electricity can affect the printing effect. In severe cases, it can damage the circuit part of the printer. Especially in the autumn and winter seasons, if the human body is too high, if you touch the print head directly, it will easily damage the circuit part of the print head. Therefore, not only the printer has a good and stable grounding, but also the operator is in contact with the machine and the print head. Be sure to do anti-static measures, such as with anti-static meters.

2. The positive and negative poles of the power supply are reversed.

This kind of operation is illegal. During the operation, try to follow the standard operation, especially the print head of the wide-format digital printing machine. If it is not necessary, try not to insert or pull the circuit to avoid the positive and negative connection of the power supply. Reverse operation.

3. Staying in the “dry burning” state for a long time

If the print head of the digital printing machine is in a “dry burning” state for a long time, it is naturally easy to be burned.

4. The working voltage is too high

If the print head is operated under high load for a long time, it is easy to cause aging of the piezoelectric crystal, especially for the piezoelectric print head.

5. Strong corrosive ink or other liquid gets on the printed circuit board

How to get strong corrosive ink or other liquid on the circuit board of the print head can easily cause short circuit, especially solvent ink. Therefore, in the process of processing the print head, we need to pay special attention to not to blot the ink onto the data line interface of the print head, which is likely to cause a short circuit. In severe cases, the print head will be burnt.

The above 5 points are the reason why the digital printing print head is burned, I hope to help you digital printing practitioners.

In the daily production of digital printing, everyone should pay more attention to the maintenance of the print head. If the print head is burned, there is usually no way to recover it. It can only be scrapped and replaced with the print head. This increases the production cost.

Does the dry environment affect the use of inkjet printers?

Everyone knows that the requirements of the inkjet printer for the working environment are relatively high, so the dry environment will not affect its use? Recently, many friends have consulted similar questions, then I will explain to you, specifically refer to the introduction below.

A dry environment can affect the normal use of inkjet printers. The technician pointed out that the amount of static electricity in the dry environment is relatively large, and the large static electricity is very harmful to it, and it will directly affect the ink. For example, the flying ink phenomenon is more serious. Also, the ink solvent is a volatile liquid. If it is too dry, the ink will evaporate faster than usual, and it is easy to cause the ink on the surface of the print head to dry out, thereby blocking the print head. Another point is that the water evaporates quickly, causing the phenomenon of solidification. It is absolutely fatal. Once the water in the ink on the nozzle evaporates, the colorants and additives in the ink will condense on the nozzle, which will block the print head. Lighter will affect the lack of printing, lack of color, etc., and the heavy one will make the ink cartridge dry and can not print. Failure to pay attention to these problems is likely to cause damage to the print head.

In addition to affecting the use of ink, the dry environment also has a certain influence on the printed materials. For example, changing the coating on some materials, so that it is not compatible with the ink, it is easy to cause the material to be edged, or the coating is excessively blotting. If these problems are not dealt with in time, it is easy to cause damage to the print head and motor.

Therefore, in order to improve the quality of our work and make the inkjet printer work better, we have to provide it with a proper working environment.
