The principle of the inkjet printer

The inkjet printing device, although inferior in quality to the laser, is still quite easy to maintain and is great for printing images and text at home. In the article you will learn about the features of the inkjet printer, which will allow you to compare it with other types.

Features of inkjet printing

Consider the features of inkjet printing:

1. Inkjet printers work quietly during printing, emitting only a slight hum. The noise level of this device is 40 decibels, which is much quieter than the work of other types of printers.
2. The quality and speed of inkjet printing are interconnected. The higher the quality is set in the options, the lower the speed, and vice versa.
3. In order to obtain a high-quality image during printing on an inkjet printer, it is necessary to use paper that has a good density. An excellent option for high-quality printing is a sheet of paper with a density of 60-135 g / m2.
4. Equipment of this type is not intended for specifying the operation "Print copies". To do this, you must perform the "print" operation of the same text several times.
5. If you do not use an inkjet printer for a long time, the ink will dry out. In this case, only changing the cartridge will help.

IMPORTANT! To keep the ink longer, when replacing the ink cartridge, the printer head must also be changed, and a separate removable container should be used.

Inkjet printer device

The main component in the operation of an inkjet printer is the print head, which receives ink. This part is mounted on a carriage, which moves back and forth across a sheet of paper, after which the coloring matter gets on the paper itself.

ATTENTION! The coloring matter cannot spill out because the nozzles have too small openings.

The operation of this equipment is as follows: after a print job, a sheet of paper enters the printing compartment, in which it is moved using the advance mechanism and is pressed against it with special rollers.

The principle of the inkjet printer

The principle of operation of an inkjet printer is that the ink enters the sheets of paper in droplet form through special nozzles. Each droplet is very small and extruded.

Depending on the manufacturer, this equipment can print using several technologies:

1. Drop-on-demand.A specially integrated mechanism in tandem with a heating element sprays ink on demand so quickly that the quality and speed of printing are significantly improved. During color printing, more contrasting and sharper image details are obtained. This method is great for printing graphs and charts - they have clear lines.
2. Thermal method. An element with the property of heating to a very high temperature when an electric current passes through it is built into each nozzle. This action contributes to the formation of gas bubbles, which displace the paint on the paper in the right amount. After turning off the current, the heating element cools down and gives out a new portion of ink. The service life of printers working with this method exceeds the life of other devices working due to other methods. The disadvantage of this method is that during continuous filling, the image looks blurry.
3. Piezoelectric method. This method consists in the fact that each nozzle has its own flat-shaped piezocrystal, which is directly connected to the diaphragm. When interacting with an electric field, it is deformed, that is, it is first compressed and then expanded, filling the system with ink. Thus, dots remain on the paper, which make up the entire image.

Continuous feed differs from on-demand feed in that the dye penetration is modulator dependent.

Advantages and Disadvantages of Inkjet Printing

Inkjet printers, like any other type of printer, have their advantages and disadvantages.

Disadvantages:

1. Print speed. Compared to a laser printer, the print speed of an inkjet printing device is much lower, although this does not interfere with its use at home. For those users who need fast printing, this equipment is not suitable.
2. The probability of ink drying. Due to a long pause in work, the paint may dry out, which will eventually lead to the replacement of the cartridge.
3. The high cost of consumables for certain models. The price of ink and cartridges of some models, as well as the cost of servicing the device in service centers is very high.

Benefits:

• low cost of the device itself;
• the ability to independently print high-quality color photographs;
• ease of refilling the cartridge at home;
• connecting a continuous supply of dyes.

These are the features, pros and cons of inkjet printing devices.
