Chapter 4 Disassembly
(1) Before starting disassembly and reassembly, always turn the AC power switch OFF, and pull out the
AC plug.
Note: Unplug the AC power cord from the wall outlet first and then from the facsimile.
(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.
