3. Press the paper door release lever to put the paper door in the open position.
4. Press upward on the logic card release tab and rotate the top of the logic card
away from the printer unit.
5. Lift the logic card up slightly to disconnect the bottom connector of the logic
card from the printer unit.
6. Note the position of the cables connected to the logic card; then disconnect
them.
