Toner Cartridges - How They Work
by Martin Smith
In the past computers and their accompanying
printers were huge. Toner reservoirs and toner
cartridges were used instead of ink cartridges like
the ones in use today. Toner cartridges were
difficult and messy to fill. The toner cartridges
were an advancement. Some printers ran on print
wheels and some used ribbons.
Computers are compact and printers now do more than
just print on some cases. Cartridges with
self-contained reservoirs are used in printers.
Refilling some cartridges is possible and it isn't
as messy as adding toner was. Two types of printers
cartridges now exist. Hewlett-Packard and Epson
printers primarily, used the first type the Peizo
Electric.
An electric current is applied to a small crystal
causing it to expand about every five microseconds
(20,000 per second). The ink, because of the
expansion, squirts through the print heads rapidly
and precisely. Piezo Electric can do more precise
action and tend to last longer because it has fewer
print heads than do bubble jet/thermal printers.
Bubble jet printer cartridges heat the ink into a
bubble and is squirted through the ink nozzles
thousands of times a second. The printer that is
quieter than Piezo based printers is the bubble jet.
It prints with exceptionally high resolution color
printing. Ink is squirted through the nozzles as
they move over media in the inkjet method not the
mega pixel method.
Liquid ink, is squirted, in various colors on the
paper to create an image. A motor assembly is used
to enable the print heads to scan the page
horizontally while the page is rolled vertically. A
narrow band of an image is printed and the paper
moves on ready for the next step. For speed it
prints a strip across the page while it also prints
vertical rows of pixels in each pass.
There are several types of inkjet technology.
DOD-drop on demand squirts small drops of ink on to
the paper through tiny nozzles. It is akin to a hose
being turned on and off 5,000 times per second. The
amount of ink dropped on the paper and which nozzle
fires and when is controlled by the driver software.
The ink tends to smear right after printing in
inkjet technology.
This is getting better as new ink compositions are
developed. The Thermal Technology of printing allows
the ink to shot onto the paper. This is a three
stage process. The squirt begins in stage one when
the ink gets heated to create a bubble. The initial
pressure breaks the bubble and hits the paper. The
vacuum that results pulls the ink from the reservoir
to replace what was ejected.
In the past printers were highly priced because the
print head that would imprint the image on paper was
contained within the printer. Printers are fairly
low in price, but the expense comes when you have to
buy cartridges for it. It would almost be worth it
to buy a new printer rather than the cartridges
because the cost of cartridges is often more than
the most basic inkjet printer.
Although cartridges are expensive they have some
complex technology in them that would make them
cheaper over-all than it would be to keep replacing
printer heads. Cartridges now have print heads
contained within in themselves. If you use the
correct cartridges in your printer, you could have
the printer for a long time. Black cartridges work
by squirting the ink through tiny nozzles onto the
paper as they move back and for the page as do color
cartridges.
Color cartridges have three reservoirs; one is
filled with magenta, one with cyan, and one with
yellow ink. A lot of things can have a bearing on
the image quality. The quality of the paper you
choose could determine the image you get. The two
main influences on image quality are brightness and
the absorption of ink. The vividness of an image
describes its brightness while how effectively ink
is put to the paper is absorption.
It is best to use paper specifically designed to be
used with an ink jet printer. Using the proper type
of paper will result in the best possible image. The
settings of your display properties and/or printer
settings can affect your printing project. The type
of paper you use and the printer may suggest leaving
your documents to dry for awhile. Check your printer
for settings that may save ink by putting out less
ink allowing documents to dry faster and provide you
with a near perfect print image.
Knowing your printer and how it works is important.
