The history of currently popular ink-jet printing, or, scientifically speaking the technology of nonimpact high-speed ink spotting through microscopic openings onto the solid carrier for producing an image on the surface of it, is more than a decade long. But the origin of this technology is actually the research of the Frenchman Felix Savart, who in 1833 have discovered and noted the uniformity of liquid drops formation when delivered through a narrow opening. It was first described mathematically in 1878 by lord Reilly (the future Nobel Prize Winner). However, many years on, in 1951, Siemens patented the first device that was separating the jet into similar drops. This invention led to the creation of minograph, one of the first commercial recorders used for the registration of voltage magnitude. Continue reading How it all began.

Usually, we don’t even think about how much time is needed for a new discovery to become applicable in our ordinary, day-to-day life. How much additional energy, finances and calculations is needed to drive those theoretical developments to their practical application.
Today, we are speaking about printing methods, and there are definitely more than a few. But we will have a closer look at the three most popular ones. Continue reading How it all began. The history of matrix printing. Part 1
Dual-component systems are analog copiers that have a source of light. In copiers it is an exposure lamp. There are two different types of cartridges used in this kind of machines. First one includes both toner and developer in a single unit, and the second type is where the developer is separated from the toner. Since this technology is not new, there are quite a few variations of it. But still, the theory is all the same for each of those. Continue reading Printing theory. Dual-component systems. Part 6
This article will mainly describe the Brother TN-460, but also it is covering other Brother drum cartridges. The toner of this cartridge is also non-magnetic, but since the working principle is very unique, Brother will have a separate article here. Also, this article will give you some tips on how to troubleshoot your cartridge. Nevertheless, the theory for all Brother cartridges is the same, the toner for each particular model is different. Using the toner from one cartridge with another, will give you quite different results. So, you need to be always sure that your current toner suits your cartridge. Continue reading Printing theory.
