Which is the toner composition?
Itīs a mix of black particles of plastic resin and iron particles.
The roller has a magnetic nucleo. While it turns around it attracs iron
particles of toner to its
surface of the cavity, the ones drag
plastic particles, that remain electronegatives when it touch
the aluminium surface of the roller, because its negatively charged.
With the spin of the roller, the lines swept by the laser beam are
going to be close to the roller, with negative particles of free toner
in the surface, and closer to the surface of the drum. When this lines
are passing front the roller, the negative particles of toner jump
to the surface of the drum, attracs by the positive points in its,
making on this cylindrical surface a image with the particles of
toner adherent to the electrostatic image, before maded with the
points that touch the laser beam. The surface negative charges of
the drum reject the toner particles.
In this moment of the roller spin, the drag system of the sheet make that
this move to other ruber roller with positive charge, being electropositive
the face of the sheet where isn't written.Then, the sheet pass along the
portion of the surface where the image was created, taking contact with her
and accompanying its spin. Now the drum transfer to the sheet (electropositive)
the image that it made, transfering the most part of the toner particles (negatives)
that it have adheres with electrostatic on its surface. Later, the sheet must
take contact with a metal rod, so that the positive charges move to mass,
resulting neutral the surface of the sheet thats passed by the rod.
.
Later, the sheet in its drag movement is submitted to pressure and heat between
2 rollers to melt the toner and then setted, on its way to the outbox.
The roller is coated y a teflon layer.
The surface of the drum pass below a paralel FLEJE next to him.that delete
the particles of toner that isn't transfered to the sheet,
and then - completing the spin - the surface pass again by the rubber roller
charged of negative electricity. This roller, in a electrostatic deleting action,
delete all the points with positive charge (generated by the lasser) that was
used for bonding the toner, being this surface negative homogeneosly.
In this form, rejects any toner particle thar could stay attached and prepare
the surface for make the process of the point 1.
