2.2 Unscrew the four mounting screws under the carriage board slots. (See Figure 2.2)
2.3 Disconnect cables ②–④ in sequence. (See Figure 2.1-1)
2.4 Remove the printhead flat cables in the original order and secure them with a rubber band to avoid confusion. (See Figure 2.4)
2.5 Unscrew the fixing screw for cable ① shown in Fig. 2.1-1, then disconnect the cable.
2.6 Cut off the cable tie securing the decoder cable ④. (See Figure 2.6)
2.7 Remove the carriage board together with its base, then unscrew the fixing screws and separate the board from the base. (See Figure 2.7-1/2.7-2)
2.8 Place the old carriage board in an anti-static bag for storage. (See Figure 2.8)
2.2 Disconnect cables ①–④ in sequence. (See Figure 2.1-1)
2.3 Hold the carriage adapter card firmly on both sides and lift it straight up together with the flat cables.(See Figure 2.3-2)
2.4 Unscrew the four corner mounting screws of the carriage board (See Figure2.4)
2.5 Place the old carriage board,and put it in an anti-static bag for storage. (See Figure2.5)
2.2 Disconnect cables ①–⑤ one by one in the indicated in sequence. (See Figure 2.1-1)
2.3 Hold the carriage adapter card firmly on both sides and lift it straight up together with the flat cables. (See Figure 2.3)
2.4 Remove the four corner mounting screws of the carriage board and disconnect the ground wire secured by the upper-right screw. (See Figure 2.4)
2.5 Place the old carriage board in an anti-static bag for storage. (See Figure 2.5)
Step 3. Install the New Carriage Board
3.1 Confirm that the new carriage board model matches the old one.
3.2 Align the new board with the mounting holes on the base, place it gently, and tighten all screws. (See Figure 2.7-2)
3.3 Use a new cable tie to fix the decoder cable securely. (See Figure 2.6)
3.4 Reconnect cable ① and tighten its fixing screws. (See Figure 3.4)
3.3 Reinstall the carriage board adapter card together with the printhead cables onto the carriage board. Ensure correct installation by following Figures 3.3-1, 3.3-2, and 3.3-3.
3.2 Align the new carriage board with the mounting holes and place it in position. Connect the ground wire at the upper-right corner first (See Figure 3.2), then tighten the screws at the upper-left, lower-left, and lower-right corners. (See Figure 2.4)
3.2 Align the new carriage board with the mounting holes and place it in position. Connect the ground wire at the upper-right corner first, then tighten the screws at the upper-left, lower-left, and lower-right corners. (See Figure 3.2/2.4)
3.3 Reinstall the carriage board adapter card together with the printhead cables onto the carriage board. Ensure correct installation by following Figures 3.3-1, 3.3-2, and 3.3-3.
3.3 Reinstall the carriage board adapter card together with the printhead cables onto the carriage board. （See Figure 2.3）
4.1 Refer to Fig. 2.1-1 Carriage Board Wiring Diagram and reconnect all cables in order.
Ensure each cable is fully inserted, oriented correctly, and firmly connected.
4.2 Reconnect the printhead flat cables in their original order.
