The electric circuit boards of the printer (Main control circuit board: C200 MAIN / Power supply circuit board:
C206 PSB/PSE) are both installed on single metal chassis and attached to the printer mechanism.
Therefore, first detach the metal chassis from the printer mechanism to remove the electric circuit boards.

1. 

Remove the upper housing (Refer to section 3.2.1)

2. 

Remove 5 screws (No.1 / three at the back of the printer mechanism and one each at both sides
of the printer mechanism)

3. 

Slightly pull out “SHIELD PLATE, M/B” (metal chassis) from the printer mechanism and take out
the cable holders inserted to the edge of “SHIELD PLATE, M/B”.

4. 

Fully separate “SHIELD PLATE, M/B” from the printer mechanism and remove all cables
connected to the connectors on the main board; C200 MAIN.

5. 

If you need further to remove each electric circuit board from “SHIELD PLATE, M/B”, remove the
screws fixing each board and remove it.

 C200 MAIN BOARD:

10 screws (No.1 = 7 screws, No.6 = 3 screws)

 C206 PSB/PSE BOARD:

4 screws (No.1)

Also disconnect the cable from the connector; CN10 (locking type) on the C200 MAIN, when you
remove the C206 PSB/PSE BOARD.

Unlock the connector CN6/7 on the C200 MAIN by pulling its lock before disconnect the cables, and be
sure to lock it when reconnecting the cables.
