Plug/Jack Diagrams and Designators
This chapter contains the Plug/Jack Designators, Locators, and wiring
diagrams for the print engine and all options.
The Plug/Jack Locator diagrams show the P/J locations within the printer. Use
these illustrations to locate the P/J connectors called out in the
Troubleshooting procedures presented in Sections 3, 4, and 5.
The Plug/Jack locators consist of the P/J Designator Tables and the P/J
Locator Diagrams.
■ The P/J column lists the Plug/Jack numbers in numerical order.
■ The Map column provides the map number of the specific areas (i.e.,
Electrical, Laser Unit...etc.)
■ The Coordinates column lists the diagram coordinates for the location of
the connector.
■ The Remarks column provides a brief description of each connection.
1. Locate the P/J connector designator in the first column of the table.
2. With this information, go to the map listed in the second column.
3. Use the coordinates to locate the connection indicated on the map with its
P/J designation number.
