Wiring Diagrams and Signal Information
Wiring Diagram Notations
This section of the manual contains a Master Wiring Diagram for the Qms Magicolor 330 laser printer. The Master
Wiring Diagram shows the interconnections of the major subsystems within the printer. The remainder of this section
divides the Master Wiring Diagram into thirteen individual block diagrams (BD) to better illustrate the electrical rela-
tionships between components and assemblies within the printer. Each wire in the diagrams is tagged with a signal
name and each wire is terminated at both ends with a pin number.
The wiring diagrams presented in this manual use the following circuit notations to describe components and signal
paths within the printer.
