Xerox 4400DT Service Manual - Page 461

Introduction This section of the manual contains wiring diagrams and plug/jack locations for the Phaser 4400 printer. The section is divided into subsections, one for each of the major assemblies that make up the printer and its options: I Base Engine I Optional Trays and Feeders I Envelope Feeder I Stacker I Duplex Unit Each subsection has one or more block diagrams that show the interconnections of the major subsystems within the assembly. This block diagram is followed by one or more individual wiring diagrams that illustrate the electrical relationships between components and assemblies within the printer. Each wire in the block diagram is tagged with a signal name, and each wire is terminated at both ends with a pin number. Location of P/J Connectors Each subsection provides a table listing the P/J connectors in the assembly, and a map showing the location of the connector. Use the P/J table and the P/J Map and to locate a specific P/J connector within the assembly. 1. Locate the P/J connector number in the first column of the table. 2. Locate the corresponding coordinates in the second column, such as I7 or J7. 3. Go to the map. 4. Cross-reference the letter and number of the P/J coordinates with the letters and numbers on the map. 5. The P/J connector is located within the area where the coordinates cross. 9-2 Phaser 4400 Laser Printer Service Manual
