4. Remove the card cage top (held by 3 screws).

5. Flip over the hinged card cage top.

6. Lift out the engine control board.

Note If you exchanged an old engine control board for a new engine control

board, be sure to exchange the NVRAM (IC 5) from the old board into

the new board. The NVRAM IC contains the printhead temperature

and sensor calibration setting. If, for some reason, you must

reprogram the NVRAM IC, perform the procedures “Thermal head

temperature adjustment” on page 9-14 and “Reflective sensor

auto-calibration” on page 9-7.

Reverse these steps to install the engine control board.
