Awarning

Because the printer mechanism is large and heavy, you must be careful when you remove it. When you lift or lower the printer mechanism, follow these precautions:

; Two people are required to remove or install the printer mechanism.

; Use the lift handles (#E656, part number B765111001) designed for lifting or lowering the printer mechanism when you remove or install it.

; To avoid straining your waist, hands, or feet, place the printer on a low table before following the steps below.

Step 1: Remove the upper case. (Refer to Section 3.2.3.4.)

Step 2: Remove the interlock switch assembly. (Refer to Section 3.2.5)

Step 3: Remove the two CBS (O) (M4x8) screws securing the green and yellow earth cables to the grounding plate. Then disconnect connectors (1) through (4) as shown in Figure 3-41. (Ensure all connectors (1) through (7) indicated in the figure are disconnected.) Step 4: Remove the CBS (O) (M4x8) screw securing the earth cable as shown in Figure 3-42.
