Invented at Xerox PARC in the 1970s, laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. In the 1960s, the Xerox Corporation held a dominant position in the photocopier market.

1976: The first commercial implementation of a laser printer was the IBM 3800 in 1976. It was designed for data centers, where it replaced line printers attached to mainframe computers. 1977: The Xerox 9700 was brought to market in 1977. 1979: In 1979, inspired by the Xerox 9700’s commercial success, Japanese camera and optics company, Canon, developed a low-cost, desktop laser printer: the Canon LBP-10. Canon then began work on a much-improved print engine, the Canon CX, resulting in the LBP-CX printer. 1981: The first laser printer designed for office use reached market in 1981: the Xerox Star 8010. The system used a desktop metaphor that was unsurpassed in commercial sales, until the Apple Macintosh.

Canon CX engine, controlled by HP software. Up until this point, each manufacturer used its own proprietary page-description language, making the supporting software complex and expensive. 1995: Xerox ran magazine print ads headlined «Who invented the laser printer? This section needs additional citations for verification. Please help improve this article by adding citations to reliable sources. Laser printing differs from other printing technologies in that each page is always rendered in a single continuous process without any pausing in the middle, while other technologies like inkjet can pause every few lines.

A4 sized page of dots at 300 dpi. In a color printer, each of the four CMYK toner layers is stored as a separate bitmap, and all four layers are typically preprocessed before printing begins, so a minimum of 4 megabytes is needed for a full-color letter-size page at 300 dpi. During the 1980s, memory chips were still very expensive, which is why entry-level laser printers in that era always came with four-digit suggested retail prices in US dollars. Memory prices later plunged, while rapid improvements in the performance of personal computers and peripheral cables enabled the development of low-end laser printers which offload rasterization to the sending PC. 1200 dpi printers have been widely available in the consumer market since 2008. 2400 dpi electrophotographic printing plate makers, essentially laser printers that print on plastic sheets, are also available. An AC bias voltage is applied to the primary charge roller to remove any residual charges left by previous images. The roller will also apply a DC bias on the drum surface to ensure a uniform negative potential.

Numerous patents describe the photosensitive drum coating as a silicon sandwich with a photocharging layer, a charge leakage barrier layer, as well as a surface layer. Laser unit from a Dell P1500. The white hexagon is the rotating scanner mirror. A laser printer uses a laser because lasers are able to form highly focused, precise, and intense beams of light, especially over the short distances inside of a printer. The laser is aimed at a rotating polygonal mirror which directs the light beam through a system of lenses and mirrors onto the photoreceptor drum, writing pixels at rates up to sixty-five million times per second. Exposing» is also known as «writing» in some documentation. As the drums rotate, toner is continuously applied in a 15-micron-thick layer to the developer roll.

The surface of the photoreceptor with the latent image is exposed to the toner-covered developer roll. Toner consists of fine particles of dry plastic powder mixed with carbon black or coloring agents. A sheet of paper is then rolled under the photoreceptor drum, which has been coated with a pattern of toner particles in the exact places where the laser struck it moments before. The toner particles have a very weak attraction to both the drum and the paper, but the bond to the drum is weaker and the particles transfer once again, this time from the drum’s surface to the paper’s surface. A radiant heat lamp is suspended in the center of the hollow tube, and its infrared energy uniformly heats the roller from the inside. Some printers use a very thin flexible metal foil roller, so there is less thermal mass to be heated and the fuser can more quickly reach operating temperature. If paper moves through the fuser more slowly, there is more roller contact time for the toner to melt, and the fuser can operate at a lower temperature.

And intense beams of light, it has a secure network connection that allows you and multiple others to print at the same time from anywhere. The laser is aimed at a rotating polygonal mirror which directs the light beam through a system of lenses and mirrors onto the photoreceptor drum, you don’t have to think twice!

FAQ

The toner is based on either wax or plastic, so that when the paper passes through the fuser assembly, the particles of toner melt. The paper may or may not be oppositely charged. The mechanism inside a laser printer is somewhat delicate and, once damaged, often impossible to repair. The drum, in particular, is a critical component: it must not be left exposed to ambient light for more than a few hours, as light is what causes it to lose its charge and will eventually wear it out. If the toner doctor blade does not ensure that a smooth, even layer of toner is applied to the developer roll, the resulting printout may have white streaks from this in places where the blade has scraped off too much toner. Alternatively, if the blade allows too much toner to remain on the developer roll, the toner particles might come loose as the roll turns, precipitate onto the paper below, and become bonded to the paper during the fusing process.

If the fuser roller does not reach a high enough temperature or if the ambient humidity is too high, the toner will not fuse well to the paper and may flake off after printing. If the fuser is too hot, the plastic component of the toner may smear, causing the printed text to look like it is wet or smudged, or may cause the melted toner to soak through the paper to the backside. Different manufacturers claim that their toners are specifically developed for their printers and that other toner formulations may not match the original specifications in terms of either tendency to accept a negative charge, to move to the discharged areas of the photoreceptor drum from the developer roll, to fuse appropriately to the paper, or to come off the drum cleanly in each revolution. As with most electronic devices, the cost of laser printers has fallen markedly over the years. Laser printer speed can vary widely, and depends on many factors, including the graphic intensity of the job being processed. The cost of this technology depends on a combination of factors, including the cost of paper, toner, drum replacement, as well as the replacement of other items such as the fuser assembly and transfer assembly. Often printers with soft plastic drums can have a very high cost of ownership that does not become apparent until the drum requires replacement. Formerly only available on high-end printers, duplexers are now common on mid-range office printers, though not all printers can accommodate a duplexing unit.

In a commercial environment such as an office, it is becoming increasingly common for businesses to use external software that increases the performance and efficiency of laser printers in the workplace. The software can be used to set rules dictating how employees interact with printers, such as setting limits on how many pages can be printed per day, limiting usage of color ink, and flagging jobs that appear to be wasteful. While monochrome printers only use one laser scanner assembly, color printers often have two or more, often one for each of the four colors. To permit a high registration accuracy, some color laser printers use a large rotating belt called a «transfer belt». Color printers usually have a higher cost per page than monochrome printers, even if printing monochrome-only pages. HP Indigo presses that uses electrostatically charged ink instead of toner, and using a heated transfer roller instead of a fuser, that melts the charged ink particles before applying them to the paper. Color laser transfer printers are designed to create transfer media which are transfer sheets designed to be applied by means of a heat press. These transfers are typically used to make custom t-shirts or custom logo products with corporate or team logos on them.

The health effects from inhaling ultrafine particles depend on particle composition, but the results can range from respiratory irritation to more severe illness such as cardiovascular problems or cancer. In December 2011, the Australian government agency Safe Work Australia reviewed existing research and concluded that «no epidemiology studies directly associating laser printer emissions with adverse health outcomes were located» and that several assessments conclude that «risk of direct toxicity and health effects from exposure to laser printer emissions is negligible». The German Social Accident Insurance has commissioned a human study project to examine the effects on health resulting from exposure to toner dusts and from photocopying and printing cycles. A much-discussed proposal for reducing emissions from laser printers is to retrofit them with filters. These are fixed with adhesive tape to the printer’s fan vents to reduce particle emissions. However, all printers have a paper output tray being an important source of particle emissions.

By their very nature, paper output trays cannot be provided with filters, so it is impossible to reduce their contribution to overall emissions with retrofit filters.
