The science behind print heads

Written by Bruce Hughes on . Posted in Tech

The first computer printer is considered to have been invented sometime in the 1950s, but people take it as read that with all the technological advances, printers have evolved a lot in the past decades. The evolution of computer printers has escalated quickly. Nowadays, companies have developed printers that can print even 3D. However, there is an entire science behind the printers, and one of the most important parts of any printer is the print head. Those who are interested in purchasing a Xaar 126/35 pl print head for instance, should simply do some quick research on the Internet.

How do print heads work?

As it was previously mentioned, print heads represent the most important piece of any printer, because it is the one that manages to transform the ink inside the cartridge into text and images on paper. There is a heating element inside the cartridge that heats the ink, and then the heated ink is expelled through nozzles. Depending on the model, a printer can have between 4000 and even 15000 ink nozzles. These tiny things expel ink on the paper surface at a velocity of ten to twenty meters per second and this process is repeated hundreds and hundreds of times every second. The print head only skims above the paper surface, transforming those millions of ink droplets into text and images.

Is 3D printing even possible?

The answer is yes, 3D printing has become possible. The first step in 3D printing is to create a virtual design of that specific object you want to print. It can either be created using a 3D modeling program on the computer, or with the aid of a 3D scanner. 3D printing can be done, depending on the printer’s model through nearly seven methods. However, there is a huge difference between 3D printing and traditional printing, because in the first case the print head does not use regular ink, but other types of materials, in accordance to what you want to print. 3D printing has escalated rapidly, taking into account that people have managed to create synthetic organs, which is definitely a huge improvement in the medical field.

How to maintain the print heads’ good condition

It is true that print heads might require great attention. In order to maintain their good condition for a longer period, it is recommended to clean them every now and then. One of the easiest methods to clean your print head is by simply accessing the printer menu on the computer. Each printer has a self-cleaning program that can be found on the printer’s menu. Another method is to resort to manual cleaning. The first step you need to make is to check the printer’s manual and read the instructions to know exactly where your print head is located. You can use either hot water or isopropyl alcohol. Pour the liquid onto a cotton swab and dab the print head. After this is done, you have to access the self-cleaning program of the printer two times and then let the printer sit.
