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