Note The two screws toward the printer front serve as a guide for reinstallation. 9. Lift and tilt the cage assembly to release it from the engine control interface board connector below the cage assembly and remove the assembly. Replacement 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 engine control board assembly under the two loosened screws. 2. Carefully lower the assembly onto the engine interface board connector. 3. Push lightly into 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. Note Ensure that all connections are firmly seated, pay special attention to the laser unit connections on the printers right side. Note After replacement of the Engine Control Board, perform the Reset Engine NVRAM procedure on page 6-150. Phaser 7700 Color Laser Printer Service Manual 7-205
