3.2.2 Removing the Board Assemblies

Since the main board (C206 MAIN) and power supply board (C206 PSB) are built in a separate bracket from
the printer mechanism, remove the whole bracket from the printer mechanism.
1. Remove the housing. (See Section 3.2.2.)
2. Remove 5 screws (No. 1) securing the main board shield plate to the printer mechanism.
3. Pull the main board shield plate out slightly, and remove the cables hung on holders A and B, shown in
the figure below. Then, remove all cables from C206 MAIN board connectors (CN11 black, CN4 yellow,
CN5 white, CN3 black, and CN8 FFC)
4. After removing all cables from the C206 MAIN board, detach the main board shield plate completely
from the printer mechanism.
5. To remove the boards from the main board shield plate, remove all screws for each board. The C206
MAIN board has 10 screws — 7 (No. 1) and 3 (No. 6) screws. The C206 PSB/PSE board has 4 screws
(No. 1). See the figure on the next page. Also, when removing the power supply board (C206 PSB/PSE),
disconnect and remove cables connecting it to the main board (CN10 locking connector).
;
Since connectors CN6, CN7, and CN10 have connector locks, be sure to release the lock before
disconnecting the cable. Also, make sure to lock the lock when installing these cables.
;
When connecting cables, be careful not to insert them in the wrong connector. Use the color codes in
step 3 to identify the correct cable for the connector.
