Replacing the LCD/Feed Switch Circuit Board
This procedure applies to both Wi-Fi 802.11 b/g and Bluetooth printer configurations.

circuit board to the top of the printer chassis.
2. Release the locks on the three ribbon cables and pull the cables free of the circuit board.
3. For Wi-Fi 802.11 b/g printer models: Disconnect the antenna from the circuit board.
Installation
1. Open the three cable connector’s cable locks. Insert the flex cables into the connectors
with the cables contacts (fingers) facing the LCD PCBA. Lock the connectors.
2. For Wi-Fi 802.11 b/g printer models: Connect the antenna from the circuit board.
3. Verify all ribbon cables are inserted straight in the connectors and are not pulled out.
