4. Part Replacement
4.1 Precautions when replacing part
(1) Before starting part replacement, be sure to disconnect the AC power cord and the
interface cables.
(a) W
hen disconnecting the AC power cord, follow the procedure shown below.
Set the MFP POWER to the OFF “O” position.
Disconnect the AC insertion plug of the AC power cord from the AC power
source.
Disconnect the earth wire from the earth terminal of the AC power source outlet.
Disconnect the AC power cord and interface cables from the MFP.
(2) Do not disassemble the MFP while the MFP is operating normally.
(3) Restrict the MFP disassembly as small as possible. Do not remove parts that are
shown in the part replacement procedure.
(4) U
se the specified maintenance tools.
(5) Disassembly should be performed in the specified order. If parts are removed in the
specified order, part can be damaged.
(6) S
mall parts such as screw and collar can be easily lost. Attach them tentatively to
their original positions.
(7) W
hen handing IC such as microprocessor, ROM and RAM, and when handling
PCB board, do not use the glove that can easily generate static electricity.
(8) D
o not place PCB directly on any equipment or on the floor.
Warning
Electric shock can occur.
When replacing the low voltage power supply, there is a danger of electric shock.
Be sure to wear an insulation gloves or do not touch the electrically conduction
areas or terminal directly by hand during the part replacement work.
It takes approx. 1 minute for capacitors to be completely discharged after the AC
power cord is disconnected. Be careful not to receive electric shock because
capacitors may not discharge in case if PCB is defective.
(
b) W
hen reconnecting the MFP, be sure to follow the procedure shown below.
Connect the AC power cord and interface cables to the MFP.
Connect the earth wire to the earth terminal of the AC power source outlet.
