LASERJET PRINTER. CREATED BY: SHELDON.
DEFINITION. A laser printer is a type of printer that uses a laser beam to produce high-quality text and graphics on paper. It works by using a combination of electrostatically charged toner and a heated fuser to transfer the toner onto the paper..
TECHNOLOGY. Laser printers are printers that use electrophotographic technology. First, data sent from a PC is converted into printing data by a print engine. The print command is converted into laser light, which is irradiated (exposed) onto a cylindrical photosensitive drum..
Key Components of a LaserJet Printer. Laser: Creates the image on the drum. Drum: Transfers the toner to the paper. Toner Cartridge: Contains the powdered ink. Fuser: Melts the toner onto the paper. Paper Tray: Holds the paper to be printed..
OPERATION. Like a photocopier, laser printers read the electronic data from your computer and beam this information onto a drum inside the printer, which builds up a pattern of static electricity. Laser beam scans back and forth across the drum. Electrical charge is created on the drum. Drum picks up toner (powdered ink) from a cartridge. Toner is transferred to paper. Paper passes through heated rollers (fuser) to melt the toner onto the paper..
ADVANTAGES. No splatter (unlike inkjet printers). Better resolution than most printers. Double-sided printing possible. Has a built-in computer with large memory. Ability to load a large amount of sheets. Low cost per page.
DISADVANTAGES. Toner is more expensive than ink-jet cartridges. Expensive to repair - lots of complex equipment inside. Fairly bulky- larger than ink-jet printers. Can't use continuous or multi-part stationary to create carbon copies like you can with a dot-matrix printer. Most expensive printer type to buy, especially colour lasers..
Environmental Considerations. Use energy-efficient models to save electricity. Recycle toner cartridges to reduce waste. Print double-sided to save paper. Properly dispose of old printers..
Conclusion. In conclusion, LaserJet printers are essential tools that provide fast, high-quality printing. They are used in a variety of settings and have many benefits. However, we should also be mindful of their environmental impact and take steps to mitigate it..
