Xerox DocuPrint P8e Service Manual

6.1 Introduction

This wiring section contains the master connection diagram, the circuit board layouts, and the circuit

board wiring diagrams.

The master connection and wiring diagram illustrates all the circuit boards and electrical components
and how they are connected.

The circuit board layout section contains the circuit board layouts and the wiring connectors. The circuit

board illustrations show the locations of the connectors and any sensors located on the board. Each
connector has an arrow that indicates the position of pin one for that connector.

The wiring diagrams illustrate the wiring connections between the circuit boards and between circuit

boards and components.
