|In today's modern, high-tech world, a computer is practically a necessity. From bulky desktops to sleek laptops to diminutive netbooks, computers have thoroughly permeated virtually every aspect of life in the UK. Along with the computer, the printer is also a necessity. Whether it's a simple inkjet or a workhorse laser printer, these devices give us the ability to share and preserve information. Laser printers are especially popular because they're reasonably priced and can print thousands of clean, crisp copies from a single, replaceable toner ink cartridge. Here's smtqatar some information about the main component of toner ink cartridges: powdered toner.
Toner is an Electrically Charged Plastic Powder
Although toner cartridges produce images on a page, toner itself is not wet like ink. Modern toner is a dry powdery plastic-based pigment that's fused onto paper with heat. Toner carries an electrical charge that attracts it to a drum inside the printer that carries an opposite charge. Then, the drum deposits the toner onto the paper, which also has an opposite charge. It's just that simple!
How a Laser Printer Works
In a laser printer, the particles inside the printer ink toner cartridge melt and bind to the paper to create images or copies of documents. A component called a fuser does the melting. In early machines, users had to handle the toner powder directly and pour it into a reservoir, a messy and time-consuming process. With the advent of toner cartridges, the powder is fully enclosed in a sealed chamber. It's also possible to refill some types of printer cartridges. Toner comes in 4 colours: black, cyan, magenta and yellow.
Early Forms of Toner and Toner Usage
At first, toner was just powdered carbon. To improve adhesion and print quality, manufacturers learned to mix the carbon powder with a plastic polymer in what's called a "melt-mix" process. Early toners also contained relatively large particles, which made for poor image quality. Eventually, the particle size was refined, with concurrent improvements in image quality. Today, manufacturers of printer toner cartridges maintain strict quality standards for particle size and distribution. Progressive manufacturing techniques now "grow" toner particles from molecular reagents. The more uniform size and shapes of toner particles results in more efficient toner use and more accurate colour reproduction.
So, the next time you're shopping for toner ink cartridges in the UK, remember that you're using a reliable SMTQATAR, safe and effective technology to produce crisp, clear and reasonably priced images.
