let me learn about printers
which are parts of a inkjet printer
print head ink cartridges carriage located on a belt
for any maintenance on printers follow the manufacturers instructions
for what to use to clean the printer and its parts
common maintenance task include——–
blowing out dust and debris vacuum access toner and calibrating print heads
when changing out toner it is important to follow any guide lines for proper disposal of old ink and toner cartridges ————
many printer manufacturers will provide a means in which to send back used ink and toner cartridges
maintenance task on thermal printers
replacing paper cleaning the heating element remove debris
maintenance task on laser printers are
replacing toner cleaning applying a maintenance kit calibration
laser printer technology to render a printed sheet of paper
1 processing 2 charging 3 exposing 4 developing 5 transfering 6 fusing 7 cleaning
which are parts of a laser printer
pick up rollers seperate pads imaging drum transfer rollers transfer belts fuser assembly
in addition to a wired connection like ———— users can share printers wireless
U.S.B.
laser printer technologies excess toner is being scraped off the drum is called————
cleaning
laser printer technologies the printer is determining how the dots should render to a page
Processing
how many dots per square inch are needed for a 300by300d.p.i print job
90000
with out these pick up rollers can easelly pick up multiple pages of paper laser printer technologies
seperate pads
laser printer technologies these charge the paper in order for the toner can properly write to the paper
transfer rollers
laser printer technologies
cleaning can be the first step or the last step in the printing process
laser printer technologies
electrical charges are used to capture an image and then render a toner onto a page
Laser printers use a seven step process to render a print job
processing charging exposing developing transferring fusing and cleaning
print queue definition
a list of print jobs currently processing on a server this can be a list of print jobs for all printers on a network on a individual user device the print que shows print jobs the user is currently processing
lase printer technology definition
Duplex Assembly a Hardware piece located on the back of a printer which allows for printing on both sides of the page
laser printer technology P.P.M.—————-
Pages per minute
laser printer technology D.P.I.
dots per inch the higher the dots per inch the higher the quality the output from the printer
which is the typical signal used for a wireless network

bonjour
an apple service for locating devices on a network
Air Print
an apple feature used for printing in a wireless local area network
the three main network types on which printers are shared are ——-
T.C.P Bon jour and air print
when a printer is shared the default share is that
everyone on the network can print to the printer
TCP is the standard for sharing printers in most
Windows and lenox envirnments
three main types of networks tcp bonjour airprint
printers and other devices such as scanners can be shared from a local connection or a network connection
Ad-hoc:
a printer can make a wireless connection to a device without the need for a wireless access point
802.11 using a standard wireless network a printer can connect to a wireless access point and then share itself on the wireless network
this is also known as infrastructure connection
Blue Tooth
a device within 10 meters of the printer can pair itself with the printer
Ethernet
a printer is connected to a server ,router or a switch using an Ethernet cable
a printer is connected to a computer using a DB9 or DB25 cable —————–
with the advent of usb this type of connection is rare
U.S.B a printer is connected to a computer using a USB cable
with the end connected to the printer most likely a USB-B connector and the end connected to the computer a USB-a connector

impact printer technologies the major components are
platen a hard material that serves as a back for the print head (note) the paper usually has holes
Impact printer technologies the major components are
ribbon a long strip of cloth with ink print head a mechanism with pins which hammers the ribbon to press ink from the ribbon to the paper the functionality of a printhead is similar to that of a type writer
which element is associated with impact printer
platen ribbon print head
maintenance task of a impact printer
replacing the ribbon replacing the print head replace the paper
impact printers
can print on multiple forms at once
Thermal printers
render print jobs on waxy - like paper these printers are often often used to print reciepts and faxes
collate
the ability to print pages in sequence (123)rather ten all pages 1 then all pages 2 then all pages 3
the first step in any printer installation is to make sure to possess the correct ——— for the printer and operating system
driver
a universal print driver will work for many printers
but lack some printer - specific features
the four configuration features for most printers are
duplex collate orientation and quality
orientation definition
the ability to control whether a print job is portrait (tall) or landscape (wide) these settings are often controlled within the application trying to print
quality definition
the ability to choose a high quality print which uses more toner or a lower quality print which uses less quality
there are two types of printer drivers
universal and specific
specific drivers
are specific to the printers installed and the operating system for which it will be installed all the available features for the system wil be present
universal drivers
drivers that work for many printers from the same manufacturer but lack printer specific features such as paper tray features or eco printing features
virtual printing print to PDF
file being printed saves as a adobe acrobat reader on similar PDF reader application
virtual printing print to file
the file being printed usually saves as a text file this option will work if the file is a basic text file but if the file contains graphics or is heavily formatted the text result will be unreadable
print to XPS virtual printing
the file being printed saves as an xml paper specification (XPS) this is micro soft technology it behaves similar to adobe pdf print rendering xps is naitivly available with windows so that without a pdf reader will tend to use this format
virtual printing print to image
the file being printed saves as a GIF JPEG or PNG file and can then be opened in any picture displaying app
there are four main possibilities four printing to a file
print to a file print to pdf print to xps print to image
ink jet printers when inkjet printers print tiny streams of ink are sent from the print head to the paper this is usually done in two ways
thermal and piezoelectric
ink jet printer technologies Thermal
ink heats up and creates a small bubble which them ejects onto the paper
piezoelectric inkjet technologies
a crystal vibrates when voltage is applied and causes the ink to break up into minute droplets which are either charged or stuck to the paper or dropped into a reservoir and recycled piezoelectric heads rarely clog as ink is sent through the print head in a constant stream
ink jet printer technologies four step process
1 paper is kept in a tray or inserted into a feeder is pulled into the printer using rollers
ink jet printer technologies four step process
as the paper rolls through the printer an assembly moves the print head side to side ink cartridges ejects the ink onto the page as the sensors on the pulley detect the position of the print head and paper
inkjet printer technologies if duplex printing is taking place —————-
the duplex assembly runs the paper back through the printer and the other side of the page gets the ink it needs
ink jet printer technologies ink cartridges
ink cartridges cosists of all black ink cartridge color ink cartridge for color ink jet printers and often a photo cartridge needs replaced always replace cartridges never refill them
ink jet technologies duplex printing
printing occurs on both sides of the paper
ink jet technologies assembly
this part controls the manner in which the paper moves through the printer assembly
