Inkjet Printer Repair And Understanding Basic Functions
By Calista Joyner
If your printer has been acting up lately and you find yourself
in need to review your inkjet printer repair options, then you
will probably find it somewhat helpful to know more about how
inkjet printers work and what printer problems are most common
with this category of printer.
Inkjet printers were a replacement for the old dot matrix printers
that were the only affordable option to laser printers for many
years. Unlike the dot matrix printers that used an impact across
a ribbon to produce an image on paper, the technology behind inkjets
allows the image to be transferred without the cartridge actually
coming into contact with the paper.
Spraying Ink On To The Paper
The tiny droplets of ink in an inkjet printer are actually forcefully
pushed out of the head of the cartridge through a matrix of holes.
This is done in a systematic and controlled way and with a good
deal of comparative force, spraying the ink onto the paper to
create the image. It is the controlled force that led to the naming
of this new technology as inkjet.
Inkjet printers work by spraying ink on the paper in a pattern
that is specified by what computer data is being sent to the print
driver and then relayed on the printer. The first step in inkjet
printer repair is checking to be sure the tiny jets have not become
clogged with ink that has dried by swabbing the printer head with
cleaning fluid.
Improvements In Technology
Since inkjet printers were first introduced to the market more
than 20 years ago, the quality has improved because of improved
technology in controlling the size of the ink droplets.
The smaller the droplets are, the better image quality is produced
on the paper. Speed and reliability have also improved significantly,
especially in the last dozen years with a major improvement in
the actuator print head, which is the part that contains the numerous
tiny nozzles that sprays onto the paper.
Micro Piezo Technology
Another, similar advancement was introduced with micro-piezo
technology that uses a crystal embedded in each tiny nozzle and
when the crystal is given an electrical charge. This would cause
vibration that would cause a controlled amount of ink to be dispersed
onto the paper.
Additional changes have come along for inkjet printer, which
have taken them from being rather slow and low quality to being
able to compete right alongside of the more expensive laser printers.
The real key to quality is what is referred to as resolution.
Resolution is referred to as dots per inch, DPI, and the higher
the resolution, the better the quality of the printed piece.
Improvements In DPI
When inkjets were first introduced the DPI was around 120. In
the early 1990’s technology brought the DPI up to 360, which was
considered almost "letter quality" for the time.
The some inkjet printers available today can print at 6000 DPI,
making it almost impossible for the naked eye to tell the difference
between a photo printed on a high quality inkjet and a print made
through photo processing.
