photoconductor

[¦fōd·ō·kən′dək·tər]
(solid-state physics)
A nonmetallic solid whose conductivity increases when it is exposed to electromagnetic radiation.

photoconductor

The type of material typically used in a photodetector. It increases its electrical conductivity when exposed to light. See photodetector and photoelectric.

When laser beam reaches the edge of photoconductor cylinder, the photoreceptor has moved in such manner so the new beam sweeps along a new parallel path.
Light source is laser diode array matrix with four rays, driven by WHIF (Writing Head Interface), and is vertically oriented in regard to the photoconductor cylinder.
Laser diodes illuminate photoconductor cylinder in line (i.e.
It is necessary to guide the formed lased beam to the photoconductor which must be illuminated across its whole width (330 mm).
As a result, laser beam is focused in only one point forming the shape of the future printing element on the photoconductor drum.
Combination of high voltage of scorotron net (-850V) applied on photoconductor drum to charge it on uniform potential and the strength of laser power (laser strength 12) to selectively discharge preset areas on photoconductor produces an electrostatic latent image (potential difference) of the original document on the surface of drum.
Regulation of the scorotrone voltage and the laser source strength enables to change the voltage of photoconductor, i.e.
Increase of pigment particles portion in liquid toner will require increase of electric conductivity of Electrolnk, which directly depends on the quality of the ink adherence on photoconductor.(Leach & Pierce, 1999.)
Such electroconductivity requires bigger potential difference on photoconductor. By increasing the laser strength, the roundness of the reproduced elements decreases minimally (the printing elements loose roundness).
This paper investigates commercial 4-beam laser diode array with 830 nm laser wavelength output which is used for creating DAD virtual image on OPC photoconductors, i.
