6.8.5 LD CONTROL BOARD REPLACEMENT

1. Open the scanner unit. (See 6.6.3.)

CAUTION

Take care not to remove the support rod while the scanner unit is open.
Disengagement of the support rod may cause the scanner unit to fall down.

2. Remove the laser control board cover [A] (2 screws).
3. Remove the laser control board [B] (1 flat cable connector, 5 connectors, 4

screws, and 1 clamp).
