The substance appears like microscopic glass beads and helps to spread the toner on the page at superfast speed, especially when making a lot of prints fast. This process is referred to as Tribo-electrification and it helps to provide negative bias to the toner so that it can cling to the drum when printing.
The yellow color comes from Pigment Yellow , which is a benzimidazolone compound. This is a very durable and stable component and it is the reason why it is used in most exterior paints. It is a polymer just like polyester that comes with more carbon strands but contains fewer chemicals on the strand.
This implies there is ample space for more molecules to slide past one another. The process of printing can be broken down into six steps. The charge that is received by the drum is lowered significantly in all the areas that were touched by the laser beam. It is also attracted by a magnet in the roller and sticks because of electrostatic charges. The paper is charged negatively. Therefore, the fuser heats a pair of rollers that melts the toner on the printing papers.
Note that the process happens fast to avoid burning the paper. After this, the drum will be ready for the next printing task. If you do a lot of color printing , one of the best options is using laser printers because they are fast, deliver better print quality, and the page yield is also high.
It is also important to understand how it works, as we have demonstrated in this post. When an image or text is being printed on paper, the printer gathers toner from the hopper with the developer.
The developer, composed of negatively-charged magnetic beads attached to a metal roller, moves through the hopper gathering toner. The developer collects positively-charged toner particles and brushes them past the drum assembly. The electrostatic image on the drum has a stronger negative charge than the beads on the developer, so the toner is pulled from the developer onto the drum.
Next, the drum moves over the paper. The paper has an even stronger negative charge than the drum, and pulls the toner particles off of the drum in the shape of the electrostatic image. At this point, gravity is the only thing keeping the toner in place.
In order to affix the toner, the paper needs to pass through the fuser rollers, which are heated by internal quartz tube lamps. The heat melts the plastic in the toner particles, causing the toner to be absorbed into the paper fibers. This is possible because the rollers are coated with Teflon, the same material that helps food slide out of non-stick frying pans. Color toner works essentially the same way as monochrome toner, except the process is repeated for each of the toner colors.
The standard toner colors are cyan blue , magenta red , yellow and black. The black is needed because the three primary colors red, yellow and blue can be combined to form any color except black. These four toner colors, when combined at varying levels of saturation and lightness, can produce millions of different shades and hues.
This quick guided tour of toner cartridges should help provide a basic understanding of how they work. The current technology of toner cartridges has allowed laser printers to dominate the office printing market.
This way, you can be able to say how cost-effective it is to use the toner cartridge. A refillable toner cartridge implies that instead of throwing away a cartridge immediately the toner is over, you add more toner and continue using it. This means three things:. For all the three other questions, it is easy to answer by simply checking the information that is printed on the box of the cartridge, but it is different when it comes to quality.
According to mrdepot. If most of the past users were happy with the print quality, you should also expect to enjoy similar good results. When using a laser printer, it is very important to understand its operation mechanics, especially how the laser cartridge works. In this post, we have demonstrated how the process of printing takes place, the main types of cartridges, and questions that can help you to identify the best one for your printer.
