3.2.6 Printer Mechanism Removal
This section describes how to remove and disassemble the printer mechanism. Before following the steps in
this section, remove the printer mechanism from the printer as described in Section 3.2.6.
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.
