If removal of the circuit board is necessary, follow these steps.
1. Disconnect AC power to the control box.
2. Carefully pull the circuit board straight out of the guides. This sometimes requires a little
extra force. Do not use pliers or another tool to pull or pry this circuit board.
3. If the circuit board is to be replaced, return it in the packaging in which you received your
replacement circuit board.
4. Install the circuit board with the component side away from the door. Slide into guides and
push firmly until it is seated in the circuit board jack.
5. Apply power to the unit and switch on. If digital panel is blank, it is possible the circuit board
is not seated properly. Disconnect power and repeat Step 4 .
6. The printer control board contains two (2) alkaline AA batteries. They require replacement
every year.
If the printer requires service, unplug the 25 pin jack and remove all the wires from the
orange terminal. Remove the four (4) bolts that secure the printer mounting plate. This will
be serviced as a complete module. Reinstall the new unit and wire up the orange terminal
as per the Decal. Plug in the DB25 five (5) conductor cable.
