Kyocera FS-9120DN Service Manual

FS-9120DN/9520DN
2-1-8
Drum
Figure 2-1-8 Laser scanner unit (2)
1 Laser diode: Generates the laser beam which forms a latent image on the drum.
2 Collimator lens: Collimates the diffused laser beam emitted from the laser diode to convert it into a cylindrical beam.
3 Cylindrical lens: Shapes the collimated laser beam to suit the printing resolution.
4 Polygon mirror: Nine-facet mirror that rotates at approximately 28031/36220 (FS-9120DN/9520DN) rpm with each
face reflecting the laser beam toward the drum for one main-direction scan.
5 Fϑ lens: Corrects for non-linearity of the laser beam scanning speed on the drum surface, keeps the beam diameter
constant and corrects for the vertical alignment of the polygon mirror to ensure that the focal plane of the laser beam
is on the drum surface.
6 Mirror: Reflects the laser beam and changes the irradiation direction.
7 Mirror: Reflects the laser beam and changes the irradiation direction.
8 BD sensor mirror: Reflects the laser beam to the BD sensor to generate the main-direction (horizontal) sync signal.
9 Cylindrical correcting lens: Corrects for the deviation of the laser beam reflected by the BD sensor mirror to the BD
sensor.
0 BD sensor: Detects the beam reflected by the BD sensor mirror, outputting a signal to the engine controller PWB
(EPWB) to provide timing for the main-direction sync signal.
