Printers and MFDs Objective 3.6 Flashcards
Wireless Connection
Comes with either Wi-Fi or Bluetooth
Infrastructure Mode
Printer is connected to the access point
Wi-Fi Direct Mode
Allows the printer to act as an access point
Bluetooth
▪ Uses a wireless point-to-point connection from the printer
to the computer
Page Description Language (PDL)
▪ Used to create a raster file from the print commands that are sent by a software application
Scalable Font
▪ Capable of being resized to any size
Printer Control Language (PCL)
▪ Developed by HP and is closely tied to the features of different printer
models
Postscript
▪ Created by Adobe and is designed to be a device-independent PDL
XML Paper Specification (XPS)
▪ Microsoft’s page description language (PDL)
Portable Document Format (PDF)
▪ Created by Adobe which keeps a file’s original look when viewed or printed on different systems
▪ PDF is larger in size than XPS format files
Print Server
▪ Software application or hardware device that manages print requests and printer queue status information
▪ Centralized print server allows to control, to configure, and to troubleshoot the devices remotely from a network
▪ Print servers are suitable for small and home offices with up to fifty servers
▪ Embedded print servers support one printer
Microsoft Management Console (MMC)
▪ Allows to share network printers and centralize the print server from the centralized window server
Printer Share
▪ Allows to connect a printer using Bluetooth or USB
Print Spooler
▪ Service built into the Windows OS and exists to help print jobs
User Authentication
▪ Sets permissions for the printer that require a log in with a username or password
Audit Log
▪ Record of jobs that have been sent and printed on a particular device
Secured Print
▪ Device held on the printer until the user’s authentication
Optical Character Recognition (OCR)
▪ Convert scanned text into digital documents that can be manipulated using a word processing program
Image Drum
▪ Main component that creates the image to be applied to the paper
Fuser Assembly
▪ Heats up and melts the toner onto the page to adhere properly to the page
Transfer Belt/Roller
▪ Used as a way to transfer the image from the image drum and become fused
Pickup Roller
▪ Used to pick up the paper from the feed tray and feed it through the
system
Paper Separation Pad
▪ Helps the pickup rollers to ensure they only pick up a single piece of paper at a time
Duplexing Assembly
▪ Moves the paper from the front to the back
Processing
▪ The OS uses a print driver to translate what’s on the screen to print
Charging
▪ The imaging drum is conditioned with the primary charge roller
Exposing
▪ The surface coding of the photosensitive imaging drum is losing its charge when exposed to light
Developing
▪ The laser printer takes the toner and applies it to a developer roller
Transferring
▪ Moving the toner from the imaging drum into the print media
Fusing
▪ The fuser squeezes the paper between a hot roller and a pressure roller
Cleaning
▪ The photosensitive drum needed to be cleaned and get all the remaining toner particles cleaned off
Use of maintenance kit
▪ Feed rollers pull up one sheet at a time and feed it through the system
▪ Transfer rollers are used to take the toner off of the imaging drum and apply it to the paper
▪ Fuser unit is responsible for heating up the toner and making it bond to the page
▪ Page count indicates when to change the feed roller, transfer roller, or the fuse unit
Calibration
▪ Process by which the printer determines the print density or color balance to use
Printhead (Inkjet Printer)
▪ Device that takes the droplets of ink and directs into the paper
Piezoelectric/Charge Method
▪ Uses a nozzle that reacts to changes in voltage
Thermal Method (Inkjet Printer)
▪ Used by HP, Canon, and Lexmark printers, and relies on heating up the ink
in the nozzle of the printhead
Roller
▪ Responsible for advancing the paper through the inkjet printer
Feeder
▪ Allows multiple pieces of paper in a tray to be selected one piece of paper at a time and passes it to the roller
Duplexing Assembly
▪ Allows an inkjet printer to print on both sides of a piece of paper
Carriage Belt/Carriage System
▪ Allows the printhead to move back and forth across the page
o Unidirectional Printing
▪ Printhead will only apply ink from left to right
Bi-directional Printing/Two-Directional Printing
▪ Apply ink from left to right and from right to left
Thermal Printer
▪ Type of printer that uses a heating element to create an image
Color Thermal Printer
▪ Uses thermal ribbon to create images
Cleaning the heating element
▪ Use isopropyl alcohol with cotton swab to clean the printhead
Removing debris
▪ Unplug the thermal printer
▪ Take out the paper role
▪ Clean the feed mechanism
Impact Printers
- Impact printers are measured based on the quality of the dots
- Impact printer has the highest resolution of 240 dpi
Tracks (Impact Printer)
▪ Series of holes going down the side of the paper with a perforation between the regular paper and tracks
Printhead (Impact Printer)
▪ Device that has a series of pins that make up the dot matrix that forms the image
Ribbon
▪ Fabric or material held within a plastic housing in front of the printhead
Tractor Feed
▪ Exists on both sides of the printer and pulls the paper through the printer using tractor fed paper
3D Printer
▪ Type of printer that creates images in three dimensions (height, width, and depth)
- A slice is one layer of the overall 3D model
Print bed/Build plate
▪ Flat plate where the material will be extruded and built
Bed/Build Surface
▪ Sheet placed on top of the base plate that hold the object into position while printing)
Extruder
▪ Printhead for 3D printers
Fan
▪ Helps to cool down the melted filament to retain the consistency
Filament
▪ Ink for 3D printers (1.75 mm or 3 m
