Replacing the Main Logic Board Circuit Board
You must remove the bottom case before performing this procedure.
Removal
1. From beneath, use a #1 Phillips screwdriver to remove the screw holding the Main Logic
circuit board to the inner mechanism.
2. Carefully lift the Main Logic circuit board away from the printer to disconnect the wires,
bundles and ribbon cables from one side of the printer and then the other. Flex circuit
cable connectors include a colored locking tab. Pull the tab up to unlock the connector.
Installation
1. From beneath, check the wires, bundles and ribbon cables.
2. Align the Main Logic circuit board over the mounting pins on the inner mechanism.
3. Connect the printer’s motor, sensors, printhead and ground cable to the Main Logic circuit
board. With the locking tab pulled up (open), slide the flex circuit cables into the
connector. Push the tab down to lock the cable. Check that all are securely attached.
4. Lower the Main Logic circuit board onto the mounting pins.
5. Place the screw back into place and use a #1 Phillips screwdriver to tighten it.
Replace the bottom case. Reload media. Plug in power, turn on the printer and print a status
report to ensure proper function.
Caution • Prepare your work area by protecting against static discharge. Your work area
must be static-safe and include a properly grounded conductive cushioned mat to hold the
printer and a conductive wrist strap for yourself.
