(a) NCU board
DIP switches to be placed in the same position as on the removed board.
Refer to Chapter 8.

have to set the LED print head strobe time by the technical function No.
26. (Refer to Chapter 5).
(2) Do not try to disassemble as long as the facsimile is operating normally.
(3) Do not remove unnecessary parts: Try to keep disassembly to a minimum.
(4) When disassembling, follow the prescribed sequence. Otherwise, parts may be damaged.
(5) Since screws and small parts are likely to be lost, they should temporarily be attached to
their original positions.
(6) When handling items such as printed circuit boards, do not wear gloves that are likely to
generate static electricity.
(7) Using a wrist band connected to the ground will protect semiconductors on printed circuit
boards from damage by the static electricity.
(8) Do not place printed circuit boards directly on the equipment or on the floor.
(9) Remove the I/D unit (image drum unit)
• Open the cover assembly-top by raising, then take out the I/D unit from the equipment.
