3.6.3 PRINTER ENGINE CTL BOARD
Preparation:
Remove platen or ADF. ( 3.2.4, 3.2.5)
Raise the scanner unit to full upright. ( 3.2.7)
Remove: (1) paper cassette, (2) paper output tray, (3) right cover, (4) left cover, (5)
scanner unit, (6) rear cover ( 3.2.8, 3.2.10, 3.2.12, 3.2.14, 3.2.15)
1. Slowly push the cover bracket from the right [1] about 4 cm (1½") to the left to
disengage the hook below then lift the plate to remove it.
Apply only enough force to slide the bracket off of its hook.
If you push too hard, the bracket may release suddenly from the frame and the
edge of the cover may shear components from the control board.
2. Touch a metal surface before you touch the control board.
3. Push the corner of the back cover [2] aside to expose the screw.
4. Remove the control board [3] (x12, FFC x2, x6).
5. The NVRAM is on the bottom of the board. Turn the board over and lay it on a flat, clean
surface so you can see the NVRAM [4].
