Welcome to the world Lexmark laser technology
with science and innovation
create a visible difference
How does a laser write on paper?
To find the answer
you have to look here
the toner cartridge
It's here, the laser printer magic unfolds
and the world of sorts and images are brilliantly produced
only outside, a toner cartridge appears simple and uncomplicated
but inside, a complex set of chemical
electrical and mechanical processes takes place
to ensure that what we create here
is accurately reproduce here
few printer owners fully appreciate the role of original Lexmark toner plays
It's not simply a receptacle filled with toner
but an assembly of more than 80 different components
Performance engineered exclusively for the printer for which it was designed
It's the heart of the printing process
how does a laser printer transform characters into a hard copy?
there are 6 distinct processes involved in producing a laser printed page
all of which occur within the cartridge
Lexmark laser technology
uses an electrophotographic process
to transfer digital data to paper
The process begins with the "charge roller"
which applies a uniform charge to the surface of the "photo-conductor drum"
Photoconductor drums are highly sophisticated components
precisely formulated to the power and the wavelength of the laser printer engine
for which they are designed
the laser strikes the photoconductor drum up to 65 million times a second
creating a chemical reaction that discharges the areas that are negatively charged
resulting in an electrostatic image
next, the image is developed
the "Toner adder roll" cuts the "Developer roll" with toner
while it's electrically statically charging the particles
as the toner is placed on the "Developer roll"
a leveling device called "Doctor blade"
even the toner to the thickness of approx. 15 microns
just like as thick as a strand of silk
as the "Developer roll" and the "Photoconductor drum"
are coming into contact
the negatively charged toner is attracted to the discharged areas of the drum
when a paper passes under the drum
the "Transfer roller" applies slightly electrical charge
causing the toner to move from the drum to the paper
the drum rotates up to 2 revolutions per second
time would be the exact speed of the paper
ensuring a complete image transfer
next, the image is made permanent
through a combination of precisely controlled heat and pressure
as the paper approaches the
The "Fuser Roller" is heated up to 225 Degree Celsius
in just 23 thousandth of a second
the toner reaches its melting point and bonds onto the page
The melting point of the Lexmark toner is
of specifically formulated for all printer fusing temperatures
ensuring satisfactory prints and protecting the life of the fuser
the final step in the imaging process
readies the cartridge to print a new page
the "Cleaning blade"gently removes any stray particles of toner
and the drum is ready to be written again
during the life of an average Lexmark cartridge
this electrophotographic process is repeated more than 100 thousands times
with so much work, it's clear to see why we recommend
our customers to use only original lexmark toner cartridges
