How does toner cartridges work?
The toner printing is based in static electricity to do the next process:
First, while a photosensitive drum rotates, an image is formed in its surface
like electropositive points, through the action of a laser beam. This electropositive points
attract toner electronegative particles, and make them appear on the surface of the drum,
the image to print made by negative toner dots.
The sheet to print is charged by a positive charge, and passes along the cylinder while
this rotates. Then attract the points with electronegative toner added to the drum,
passing the image of the drum to the sheet. Later, the toner added to the sheet must
be melted by heat.
This process its knows as "laser print", although there are other methods to produce the same
effect sucha as laser beam, using the LED's or with LCS.
While matrix printers needles or inkjet print on the paper line by line,
photostatic printers generate (in three drum turns) a complete page.
The laser printers are based in an homonymous photocopiers printer system.
On these, from the image in the sheet to photocopy by a potent lamp,
this make a electrostatic image in the photosensitive surface (selenium )
in the drum. This is because the surface of the drum convert the optical
image -generated by light reflected by the image to copy, that impact focused
in the drum- in its electrostatic equivalent, who adheres the toner, because
is made by electric charge particles contrary to the electrostatic image.
A laser printer doesn't have like in a photocopier a original image on the sheet,
but in this exist like a orderly matrix of 1's and 0's to print, in the memory of
the printer. If this print in white and black, a 1 make that the microprocessor
that governs the printer turn on the lasser that sweeps the surface of the cylinder.
When the beam touch a point on the surface, becomes in a point with positive charge,
and the particles of toner particles will adhere to this. The 0's don't turn on the beam,
resulting points that will not adhere to the toner, and later will be white points in the paper.
Here's the components of the toner cartridge:
1. Toner cartridges: A toner cartridge is
a component interchangeable of the printer that
contains the necessary toner for print in sheet and every
time that this ends, change by a new one or a remanufactured.
This is integrated by vital pieces like here we'll see: .
2. Cleaner blade: this piece clean the drum of
the toner, for start a new cicle.
3. Drum: This is the heart of the laser printer
with a coating thats allows keep a electrostatic charge.
One laser passes through the surface, putting selectively
points of positive charge, that will represent the image.
The wide of the drum it's the same that the sheet where will
appear the image.
4. PCR: toner Cartridges:
5. Metering blade: This piece dosed the needed
quantity of toner to print correctly.
6. Magnetic roller: toner cartridge
7. Chip: Contains vital information for..
