T/F: If loose toner comes out with your printout, the fuser is not reaching the proper temperature and professional service is required.
True
T/F: Some advanced printers have print server programs included in the printer firmware itself.
True
T/F: For heavy business use, the best practice is to purchase one machine for one purpose, instead of bundling many functions into a single machine.

use a can of compressed air to blow off the toner
What kind of printer works by placing toner on an electrically charged rotating drum and then depositing the toner on paper as the paper moves through the system at the same speed the drum is turning.

remote printing
the act of printing to a printer on a network connection
XPS file
a type of file similar to a PDF, can be viewed, edited, printed, faxed, emailed, or posted on websites
extension magnet brush
long-handled brush made of nylon fibers that are charged with static electricity
bitmap
a bunch of bits in rows and columns
calibration
used to align and/or clean inkjet nozzles, can solve problems when colors appear streaked or out of alignment
inkjet printer
uses a print head that moves across the paper creating one line with each pass
raw data
data sent to a printer without any formatting or processing
laser printer
a type of electrophotographic printer that can range from a small, personal desktop model to a large, network printer capable of handling and printing large volumes continuously
impact printer
creates a printed page by using some mechanism that touches or hits the paper
List four things to try when troubleshooting poor print quality with an inkjet printer.
- check for correct paper
- check ink supply
- remove and reinstall cartridge
- check print head
List three requirements for a high-end CAD/CAM workstation.
- powerful multicore processor
- fast hard drives
- high-end video card
Describe the cleaning step of laser printing.
sweeper strip cleans drum, charge that is left is neutralized (some use red lamps as to not damage photosensitive drum)
Describe how an inkjet printer works.
uses ink-dispersion printing and doesn’t usually provide high-quality resolution of laster printers.
contains firmware that processes image.
Describe the fusing step of laser printing.
fuser assembly uses heat and pressure to fuse the toner to the paper. fusing rollers use heat to melt toner and apply pressure to bond toner to paper.
Describe the exposing or writing step of laser printing.
laser beam controlled by motors and mirror scans across drum until it completes correct number of passes.
turned off and on as it makes passes.
dots exposed only where toner should go to print image.
Compare and contrast local versus network printer.
local printer connects directly to a computer (usb, parallel, wireless connection).
network printer connects with either ethernet port or wifi to connect directly to the network.
Describe the function of an impact printer.
creates a printed page by using some mechanism that touches or hits the paper.
How do you stop and restart the Windows Print Spooler service?
to stop service:
start> services> enter> select Print Spooler> click stop
to delete:
explorer> delete files in folder> start spooler back up
to start up spooler:
services> print spooler> restart> close services
How does a color laser printer operate compared to a regular laser printer?
writing process repeats four times (one for each toner color CMYB).
each color requires separate image drum.
fuser bonds all toner to paper and blends to form specific colors.
