Achieved by using magnetized plates which direct the ink's path. Capable of producing high quality print. Resolution of 300 dots per inch, although newer models have improved on that.PowerPoint Presentation: Laser printers Operate by shining a laser beam to produce an image on a drum. The drum is then rolled through a pool, or reservoir, or toner, and the electrically charged portions of the drum pick up ink. Finally, using a combination of heat and pressure, the ink on the drum is transferred onto the page. Laser printers print very fast, and the supply cartridges work a long time.PowerPoint Presentation: Identical to laser printers in most ways. Both LCD and LED printers use a light source instead of a laser to create an image on a drum. LED printers use Light Emitting Diodes to charge the drum and LCD uses Liquid Crystals. LED/LCD printersPowerPoint Presentation: Impact (Dot-matrix) printers Use of set of closely spaced pins and a ribbon to print letters or other characters on a page. They can run at a speed anywhere between 50 and 500 CPS (Characters Per Second). Dot matrix printers are commonly used for printing invoices, purchase orders, shipping forms, labels, and other multi-part forms. Dot matrix printers can print through multi-part forms in a single pass, allowing them to produce more pages than even high-speed laser printers.PowerPoint Presentation: Solid Ink printers printers that use solid wax ink sticks in a "phase-change" process. They work by liquefying wax ink sticks into reservoirs, and then squirting the ink onto a transfer drum. Then it is Cold-fused onto the paper in a single pass. Better color consistency. Solid ink machines have better reliability, because they have fewer components in comparison.PowerPoint Presentation: Dye Sublimation printers It is a Professional device widely used in demanding graphic arts and photographic applications. These printers work by heating the ink so that it turns from a solid into a gas. The heating element can be set to different temperatures, thus controlling the amount of ink laid down in one spot. In practice, this means that color is applied as a continuous tone, rather than in dots, as with an inkjet. Dye sublimation requires particularly expensive special paper, as the dyes are designed to diffuse into the paper surface, mixing to create precise color shades.PowerPoint Presentation: Portable printers Usually fairly lightweight and sometimes carry the option of using a battery instead of drawing power from the computer. You can find on the market the following types of the portable printers: Thermal printer, Thermal transfer printer and Ink-Jet printer. The main advantage of thermal and thermal transfer printers is that they can be very small. The smallest thermal and thermal transfer printers weigh approximately one pound. Thermal printers require a special type of paper.PowerPoint Presentation: Plotters large-scale printers that are very accurate at reproducing line drawings. They are commonly used for technical drawings such as engineering drawings or architectural blueprints. The two basic types of plotters are called flatbed plotters and drum plotters. Flatbed plotters are horizontally aligned with a flat surface to which a piece of paper is attached. Drum plotters, also called upright plotters, are vertically positioned. They have a drum that the paper rolls on.PowerPoint Presentation: Digital Photo printers Many middle range printers are now able to print photo quality images. Usually an option with color printers, specialist photo print heads allow a greater resolution to be achieved to improve photo image quality. Photo ink jet printers expand their gamuts by adding additional ink colors, usually light cyan and light magenta.PowerPoint Presentation: Network Printer provides output capabilities to all network users.PowerPoint Presentation: Multifunction printer Combine top-quality color ink-jet or laser printing with plain-paper and PC faxing, color copying and color scanning , telephoning- all in one convenient, space-saving machine. If you work from home or have a small office a multifunctional device may be ideal. The Bravo AutoPrinter It is the world’s first automated CD/DVD printing system that can truly be called innovative. It combines automatic, robotic-based CD or DVD printing along with full-color, 2400 dpi disc printing all in one compact, desktop unit.PowerPoint Presentation: EZ CD/DVD Printers Provide a low cost way to create professional printed CDs and DVDs. Instead of writing on the CD or applying labels, you can print directly on the CD surface! With high speed capabilities, a full color image can be printed directly on the top surface of your CDs in less than 1 minute.PowerPoint Presentation: Printers for banking These printers realize innovative technology and functionality to increase productivity, and reduce costs. Label Printers They are the smartest way to print labels one at a time. The printers allow easy installation. You can get high-quality, professional results every time.PowerPoint Presentation: VersaLaser™ (Universal Laser Systems Inc.) It is peripheral tool, that can transform images or drawings on your computer screen into real items made out of an amazing variety of materials… wood, plastic, fabric, paper, glass, leather, stone, ceramic, rubber and it’s as easy to use as your printer. Two models of VersaLaser have 16"x12"(VL-200) and 24"x12"(VL-300) work areas.PowerPoint Presentation: 3D Printers ( Z corporation ). The ZPrinter 310 System creates physical models directly from computer-aided design system (“CAD”) and other digital data in hours instead of days. The printer is fast, versatile and simple, allowing engineers to produce a range of concept models and functional test parts quickly and inexpensively. The system is ideal for an office environment or educational institution, providing product developers easy access to a 3D Printer.PowerPoint Presentation: How an inkjet printer works:- At the heart of an ink jet printer are thousands of high-precision microscopic nozzles which are typically about 10 micrometers in diameter which eject ink onto the paper. The ink jet nozzles are all mounted together on a moving carriage assembly that moves at high velocity (typically > 1 meter per second) back and forth across the paper. The nozzles are mounted about 1 mm from the paper, and ink ejection velocities are in the range of 5 to 10 meters per second. Ink is ejected from a nozzle by applying a pulse of pressure to the fluid ink in the supply tube, upstream of that nozzle. There are two common methods of creating this pressure pulse: 1 Thermal bubble 2 Piezoelectric.PowerPoint Presentation: times in volume. This volume expansion creates a pressure pulse in the fluid, causing ink in the nozzle to be ejected toward the paper. After several microseconds, the vapor bubble cools and collapses. Then the surface tension of the ink meniscus in the nozzle pulls in more ink from the reservoir to refill the nozzle in preparation for the next drop to be ejected. 1.Thermal BubblePowerPoint Presentation: 2.Piezoelectric Piezoelectric materials are crystalline materials having the property of deforming when high electric fields are applied across them. Two configurations are commonly used A] piezoelectric rods which elongate under applied fields B] bimorphs which bend (in a geometry similar to a drum head). In either case, they deform one of the walls of the ink channel leading to each nozzle. The electrical pulses which energize these piezoelectric elements are once again in the microsecond range. This deformation squeezes the channel, creating a pressure pulse and ejecting ink from the nozzle.PowerPoint Presentation: Print head assembly 1.Print head - The core of an inkjet printer, the print head contains a series of nozzles that are used to spray drops of ink. 2.Ink cartridges Depending on the manufacturer and model of the printer, ink cartridges come in various combinations, such as separate black and color cartridges, color and black in a single cartridge or even a cartridge for each ink color. The cartridges of some inkjet printers include the print head itself.PowerPoint Presentation: 3. Print head stepper motor A stepper motor moves the print head assembly (print head and ink cartridges) back and forth across the paper. Some printers have another stepper motor to park the print head assembly when the printer is not in use. Parking means that the print head assembly is restricted from accidentally moving, like a parking brake on a car. 4.Belt A belt is used to attach the print head assembly to the stepper motor.PowerPoint Presentation: 5.Stabilizer bar – The print head assembly uses a stabilizer bar to ensure that movement is precise and controlled.PowerPoint Presentation: 6.Paper feed assembly A] Paper tray/feeder – Most inkjet printers have a tray that you load the paper into. Some printers dispense with the standard tray for a feeder instead. The feeder typically snaps open at an angle on the back of the printer, allowing you to place paper in it. C] Paper feed stepper motor – This stepper motor powers the rollers to move the paper in the exact increment needed to ensure a continuous image is printed. B] Rollers – A set of rollers pull the paper in from the tray or feeder and advance the paper when the print head assembly is ready for another pass.PowerPoint Presentation: 7.Control circuitry – A small but sophisticated amount of circuitry is built into the printer to control all the mechanical aspects of operation, as well as decode the information sent to the printer from the computer. The mechanical operation of the printer is controlled by a small circuit board containing a microprocessor and memory. 8.Interface port(s) The parallel port is still used by many printers, but most newer printers use the USB- port. A few printers connect using a serial port or small computer system interface ( SCSI ) port.PowerPoint Presentation: HOW WE LOOK AT ITPowerPoint Presentation: presentation You do not have the permission to view this presentation.
