board. Use caution when removing the board so these spacers are not
lost.

If you are replacing the keypad board, move the keypad buttons to the
new board. If you are replacing the keypad buttons, install the new
buttons in the appropriate place on the keypad board.
When installing the keypad buttons, align the holes in the board with the
corresponding shafts on the back of the buttons. Gently pull the shafts
through the other side of the board to lock the buttons in position. Use
caution not to pull the shafts too hard, or they may break.
9 Ensure the spacers are in position between the keypad board and the
plate. Then install the keypad board in the bottom plate with the ten
nuts.
10 Install the display board with the four screws. The board must be
oriented so the J2 harness is facing the associated connector. Otherwise,
the harness will not reach the associated connector.
Plug in the two connectors.
11 Turn the bottom plate over in its correct orientation. Then feed the
ribbon cable through its hole in the main plate. Carefully slide the
bottom panel into place while feeding the ribbon cable through the hole.
Use caution so the cable is not damaged.
12 Align the bottom panel holes with the corresponding holes in the frame.
Then replace the four screws. Ensure all of the screws are set in place,
and then tighten each screw.
13 Connect the ribbon cable to P11 on the controller board. This connector is
slotted and will fit only in the correct orientation. Do not force the
connection.
14 Re-install the back cover.
15 Plug in the printer and turn the power on.
