How do laser printers work? This is one of the questions that most people ask and yet, they never take time to uncover the answers. Majority of people know that they only need to click on print and the rest is taken care of.
This is what they know and they are not interested in learning more. However, if you intend to get the most out of laser printers, it is ideal to learn the basics of how they work.
Part of the reason people don't look into how laser printers work is because they are not interested in learning the chemistry behind it. However, this should not be the case since the chemistry is not as complicated.
Whether you are using a Cannon, Epson or HP laser printer, they work in the same manner and this involves positive and negative charges. Laser printers use static energy where the opposite fields stick together. The phenomenon is used as temporary glue.
If you have questions on how do laser printers work, you need to understand the role played by the drum. Laser printers are designed with a drum. This turns slowly when the printing starts.
With every turn, a charge is given off by a corona charge wire or in other cases by another roller. Once the drum is fully charged, a laser is shot by the printer to the drums surface and this discharges the drum in specific places.
These spaces look like numbers and letters on the printers drum. In order to get the number shapes and discharged letters off the lasers drum and on the paper, the laser printer uses charged toner.
Then, it hooks these with a paper that is oppositely charged. Since the toner gets attracted by the paper, you end up with toner on your paper.
For people who have changed toner catridges, you can bear witness to the fact that the toner attaches itself to almost anything. This process is engineered in a manner that ensures the toner attaches itself in an orderly manner of numbers and letters.
If you also have questions on how do laser printers work on language. There is a special language used during the printing process and some of these include PCL (Printer command Language) and Postscript.
Both languages are used to describe the page while it is in its vector form and basically, this includes mathematical values rather than dots. The printer is the one that takes the vector images then converts them to bitmap page.
Thanks to this system, the printer is able to receive elaborate to complex images and carry out the complete printing exercise without any issues.
Also, because the laser printer creates its own bitmap image, it uses the printer's maximum resolution. In the majority of laser printers, there is a controller and it organizes the data received from a host computer.
Ideally, this includes commands of what the printer is supposed to do. This might include formatting the page and handling the font of the data. The controller must ensure that this information is conveyed appropriately.
Up to this point, the process is all but complete at least, to the basic level. The only thing remaining to complete the process is for the toner to get fused on paper permanently.
In order to accomplish this end, the laser printer then rolls the paper using a heat roller. This ensures that the toner is properly melted onto the papers fibers.
As the printer carries this out, another roller is used to ease the charge. Once the process is completely in sync, you don't witness any mess. For the laser printer to deliver the desired result however, everything must be timed appropriately.
