Printers & Multi-Function Devices Flashcards
Use focused light, electrical charges, and a dry powder ink (called toner) to transfer an image using to paper
Laser Printer
Six stages of a Laser Printer
Cleaning Charging Exposing Developing Transferring Fusing
Helps to prevent registration errors that can cause color fringing, blurring, or streaking along the edges of the printed colors.
transfer belt
Use ink-dispersion and wet ink to transfer an image onto paper.
Inkjet Printers
Using this method, tiny heating elements heat the ink to create a bubble. Pressure forces the bubble to burst and eject ink droplets onto the paper from the print head’s nozzles
Thermal technology
Using this method, a current is applied to a Piezo crystal at the rear of the ink reservoir. The current causes it to flex and force a drop of ink out of the nozzle. This is an Epson’s proprietary inkjet technology.
Piezo-electric technology
Work by banging a print head or needle against an ink ribbon to make a mark on the paper, very similar to an old typewriter.
Impact Printers
Uses a wheel-shaped printing mechanism containing predefined character glyphs arranged like petals on a flower.
Daisy-Wheel Impact Printer
Prints one character at a time using a print head made up of small pins. The pins are individually struck against the ribbon to create a pattern of dots which can form characters or pictures. Print heads typically have between 9 and 24 pins
Dot Matrix Impact Printer
Prints an entire line at once, allowing faster output. Might use a wide comb to produce dot matrix output, or it might have character glyphs arranged on a drum, chain, or bar.
Line Impact Printer
Method in which a series of plastic or rubber rollers move a sheet of paper through the printer. It doesn’t require special paper, and is the same method used by most inkjet and laser printers.
Friction Feed
Method in which two sprocket wheels are mounted on either side of the printer which feed paper that has perforated holes on each side which fit over the sprockets so that they can feed it through the printer. The paper has perforations at the side so that you can remove the feed holes after printing.
Tractor Feed
Requires heat-sensitive paper. The paper is moved by a feeder roller to the print head. The print head applies heat to the paper to form letters and images
Direct thermal printing
Uses ribbon printer cartridges containing waxy ink. The print head heats the ink on the ribbon and transfers it to the paper.
Thermal transfer printing
Uses solid blocks of waxy pigment which are melted and dispersed onto the paper in a method very similar to inkjet printing.
Solid ink printer
The laser projects the image on the photosensitive drum.
Laser Print Exposing
The pickup rollers grab a single sheet of paper from the paper tray and move it into the printer.
Laser Print Transferring
A physical and electrical process wipes the previous image off the photosensitive drum.
Laser Print Cleaning
The paper passes through rollers that apply heat and uniform pressure to the paper and toner, curing the image onto the paper.
Laser Print Fusing
The drum passes by an evolving roller covered in toner.
Laser Print Developing
The primary corona wire applies a negative electric matter to the photosensitive drum.
Laser Print Charging
The printer which uses ink-dispersion and wet ink to transfer an image onto paper
Inkjet
The printer which works by banging a print head or needle against an ink ribbon to make a mark on the paper
Impact
An all-in-one printer which contains additional technologies such as scanner, fax, and copier
Multifunction
An application that replicates the software interface for a physical printer and allows the user to carry out various tasks without actually printing anything.
Virtual
The printer which uses an automated process to add source material to an object, building it from the ground up
3D
Uses solid blocks of waxy pigment which are melted and dispersed onto paper.
Solid Ink Printer
Uses ribbon printer cartridges containing waxy ink.
thermal transfer printing
Requires a heat-sensitive paper.
