Replacement Procedures
Note
Before re-installing the assembly, widen the gap in each of the two white
nylon retainers to ensure that they successfully engage the interface board
bracket. Mis-alignment prevents a good connection to the interface board.
1. Tilt and insert the electrical chassis under the two loosened screws.
2. Carefully lower the assembly onto the engine control interface board connector.
3. Push lightly in the center of the assembly to ensure the assembly is fully seated.
If board is reasonably stable, the board is properly placed.
4. Continue installation by reversing the removal procedures.
Caution
Ensure that all connections are firmly seated, pay special attention to the
laser unit connections on the printers right side and to the Interface Board.
Note
After replacement of the engine control interface board, perform the
"Diagnostic Engine NVRAM Reset" on page 6-20.
