A) Plug in the keypad cable to the PCB connector.
Make sure you get ‘Pin 1’ plugged in to the correct
pin on the board.
Note: Make sure you don’t miss a row of pins on the
board connector. Missing a row of pins may
cause un-repairable damage to the main logic
board.
B) When you think all the connections are correct
plug in and power on the FlexJet to make sure it
operates properly.
C) When the machine is back to normal operation
install all the covers on the machine.
Note: When installing the PCB cover on the bottom,
make sure the keypad cable doesn’t get
pinched between the cover and the body.
