Printer Types 3.7 Flashcards
creates an entire page at one time during the printing process
laser printer
heats up the melts the toner onto the page to adhere properly to the page
fuser assembly
main component that creates the image to be applied to the paper
image drum
used as a way to transfer the image drum and become fused
transfer belt/ roller
used to pick up the paper from the feed tray and feed it through the system
pickup roller
moves the paper from the front to the back
duplexing assembly
helps the pickup roller to ensure they only pick up a single piece of paper at a time
paper separation pad
the OS uses a printer driver to translate what’s on the screen to print
Processing
the imaging drum is conditioned with the primary charge roller
Charging
the surface coding of the photosensitive imaging drum is losing its charge when exposed to light
exposing
the laser printer takes the toner and applies it to a developer roller
developing
moving the toner from the imaging drum into the print media
transferring
the fuser squeezes the paper between a hot roller and a pressure roller
fusing
the photosensitive drum needed to be cleaned and get all the remaining toner particles cleaned off
cleaning
Charging voltage is ___ Volts DC
- 600
store the paper in a nice dry area that does not have high humidity or excessive dust
loading paper
standard toner cartridge has 2500 pages and high yield cartridge has 6000 pages
toner cartridges replacement
feed rollers pull up one sheet at a time and feed it through the system
use of maintenance kit
____ rollers are used to take the toner off of the imaging drum and apply it to the paper
transfer
___ unit is responsible for heating up the toner and making it bond to the page
Fuser
___ count indicates when to change the feed roller, transfer roller or the fuse unti
page
if toner gets on the skin, wash it with cold water, do not compressed air, and some printers with filters must be kept free from dust and dirt
Cleaning the printer
____ printer creates an image on the paper through a nozzle or jet on a print head onto the paper
Inkjet
device that takes the droplets of ink and directs into the paper
printhead
uses a nozzle that reacts to changes in voltage
Piezoelectric / charge method
used by HP, Canon, and lexmark printers, and relies on heating up the ink in the nozzle of the printhead
Thermal method
responsible for advancing the paper through the inkjet printer
roller
___ method replaces the printhead when replacing the ink cartridge
Thermal
___ method doesn’t need to replace the printhead when replacing the ink cartridge
Piezoelectric
allows multiple pieces of paper in a tray to be selected one piece of paper at a time and passes it to the roller
Feeder
allows an inkjet printer to print on both sides of a piece of paper
duplexing assembly
allows the printhead to move back and forth across the page
carriage belt / carriage system
printhead will only apply ink from left to right
unidirectional printing
apply ink from left to right from right to left
bi directional printing/ 2 directional printing
type of printer that uses a heating element to create an image
thermal printers
300- 600 dpi
laser printer
100-300 dpi
thermal printer
uses thermal ribbon to create images
color thermal printer
cleaning the heating element
use isopropyl alcohol with cotton swab to clean the printhead
removing debris
unplug the thermal printer, take out paper, and clan the feed mechanism
series of holes going down the side of the paper with a perforation between regular paper and tracks
Tracks
device that has a series of pins that make up the dot matrix that forms the image
printhead
fabric or material held within a plastic housing in front of the printhead
ribbon
exists on both sides of the printer and pulls the paper through the printer using ____
Tractor feed
type of printer that creates images in three dimensions (height, width, and depth)
3d printer
flat plate where the material will be extruded and built
print bed/ build plate
sheet placed on top of the base plate that hold the object into position while printing
bed / build surface
printhead for 3d printers
extruder
helps to cool down the melted filament to retain the consistency
fan
ink for 3d printers
filament
