Replacing the Controller Board
Attention: Ensure that the printer is powered off before installing or removing the Controller
Board.
If the Controller Board is installed while the printer is powered on, the controller will not
synchronize with the printer mechanism board.
Unpredictable printer behavior will result.
Perform the following steps to replace the Controller Board:
1. Ensure that the printer is powered off. Installing the Controller Board with the printer
power on will result in unpredictable printer behavior.
2. Use the screwdriver that came in the Controller Board box to remove the existing
Controller Board and pull out the card.
3. Use the information under "Handling the Controller Board" on the preceding page as you
remove the Controller Board from its shipping box and from the protective package.
4. Align the left and right sides of the Controller Board with the guides in the printer and
slide it into the slot.
