Printers today is no longer just a means of printer paper from your PC (computer) to the paper. More than that, use the printer started to spread to various lines, call it as interpreter prints or copier that can reproduce various kinds of documents.
When talking about laser printers that in fact many users rely on an office to perform everyday document production. Even some companies, the document is considered as the spearhead in the development business. So, do not be surprised if many companies today that started to dress smart for the document they could win the tender or to maintain corporate image.
Early History of Laser Printers
If you are a walk and saw a store, look at their board service that broad! If seen the word "Xerox Copy Service", then surely this place provides photocopies of documents complete with perniknya. Xerox brand is attached to something to do with photocopies.
Understandably, the company that built since 1906 in the United States this year, it focuses its business in the field of copying documents. But since Gary Starkweather, a researcher at Xerox, to change the system pengkopi this document into a laser printer, Xerox's business began to explode as the ruler of the printer market in the '70s.
Laser printer users since it was first introduced to continue to grow, as well as with technology. Crowded market makes one laser printer device players, Minolta, began to think to follow manufactures laser printers. In 1993, hadirlah Minolata products ColorScript Laser 1000, which can produce color documents and marketed at a price of U.S. $ 12.499.
It was not until mid 1995, Apple Computer began to follow in the footsteps Minolta color laser printer to produce by presenting the Apple Laser Writer 12/600PS who can score with a maximum resolution of 600 × 600 dpi and armed with an internal memory of 2MB. Price Apple printers are also sold at a price that is cheaper (U.S. $ 7,000) compared with printers made by Minolta.
How Color Laser Printer Work?
Embedded technology behind the printer (inkjet and laser) is always interesting to follow. If the inkjet printers are widely used at home and small office built of fluid technology, in contrast to a laser printer that uses ink media in the form of powder, or commonly known as toner. No matter whether a color laser printer has the facilities or not, in principle, these devices have a way of working together, namely by using static electricity.
These are the main reasons why laser printers should use a toner as a medium of ink. At a minimum there are 6 key components that need a laser printer to work, the light-sensitive drum, fuser, neutralizing lamp, corona, laser unit, and toner.
When information is sent from a PC (computer), printer turn it into a special data that is ready to be written by the laser unit to the photosensitive drum surface. The charge on the surface of the drum which tercahayai electron laser will be changed from positive to negative electrons.
Furthermore, the drum will rotate through the tub and pulled the toner toner (positive charge) according to the pattern was written by a laser. As she passed the paper with a stronger negative charge, the toner which was originally located on the photosensitive drum will move again to the surface of the paper. Residual negative charge on the electron-sensitive drum will immediately neutralized by neutralizing lamp (corona) and ready to write next data. So forth, until all the data printed on a paper.
Toner powder stuck to the paper surface melted by the fuser with a high temperature to blend with the fiber paper. So it is not surprising that all the newly printed document from a laser printer will feel hot to the touch. The concept also applies to similar work in color laser printers.
But, this type of laser printer that has a number of light-sensitive drum, laser unit, lamp neutralizing, corona, and the toner is more than 1 piece, depending on the number of colors supported by the printer. Difficult yes also create a color laser printer?
