is toward the rear of the machine.

2. Keep the transparent side of the lamp

toward the reflecting plate.

3. Do not touch the transparent side of the

lamp.

Figure 4-505

8) Execute ‘R&D SHADING’ (12th screen) in

service mode (*3*; ADJUST). (shading for
R&D and factory)

B. CCD Unit

1. Removing the CCD Unit

1) Disconnect the power plug.
2) Remove the copyboard glass.
3) Remove the CCD unit cover
