Printer systems description
See the illustration “Printer component systems” on page 1-23,
for more information.
Basic principles of color printing
Color printing is made through the subtractive process of combining
the three primary colors: yellow, magenta, and cyan.
Mechanical and electrical structures
This color laser printer consists of five engineering systems: print,
transfer, optical, paper transport, and control system.
Print system
The print system consists of six functional parts located around the
optical photoconductor (OPC) belt and forms a toner image on the
OPC belt: charge, expose, develop, first transfer, discharge, and
clean.
Transfer system
The transfer system consists of three functional parts that transfers
the toner image formed on the transfer belt to paper: transfer belt
unit, second transfer, and cleaning roller.
Optical system
The optical system consists of two functional parts that forms an
electrostatic latent image on the OPC belt using a laser light: optical
unit and scanner motor (SCM).
Paper transport system
The paper transport system consists of five functional parts that
picks up paper from the paper tray, separates the transported paper
from the transfer belt, and exits it from the printer after fusing the
toner image on the paper: paper tray, transport, fuser, and paper
exit.
