This section covers the procedures for the disassembly, reassembly and installations in the field. This
section describes the disassembly procedures, and for reassembly procedures, basically proceed with the
disassembly procedures in the reverse order.
9.3.1 Precautions Concerning Parts Replacement Use good anti-static precautions.
Note: Parts replacements must be carried out, by first turning the OKIFAX power switch off O and
removing the printer from the High Capacity Second Paper Feeder.
1. Do not disassemble the High Capacity Paper Feeder if it is operating normally.
2. Establish the extent of disassembly suitable for the purpose of the procedure, and do not disassemble
any more than necessary.
3. Only specified service tools may be used.
4. Disassembly must be carried out according to the prescribed procedures. Parts may be damaged if
such procedures are not followed.
5. Small parts such as screws and collars can easily be lost, therefore these parts should be temporarily
fixed in the original location.
6. When handling printed circuit boards, do not use any glove which may generate static electricity.
7. Do not place the printed circuit boards directly on the equipment or floor.
