O REMOVE THE POWER SUPPLY
When you handle electronic components, follow electrostatic discharge (ESD) precautions
(see
page 10 ).
1 Remove the imagePASS from the copier (see page 14 ).
As part of this step, you must disconnect the power cable. Do not proceed until you have
done so.
2 Open the imagePASS (see page 15 ).
3 Disconnect the following
• The two power supply cables connected to the motherboard (see page 21 )
• The power supply cable connected to the hard disk drive (see page 21 and page 22 )
• The black and white cables connected to the power switch (see page 22 )
4 Make note of the cable ties and how cables are draped. Carefully cut the cable ties that secure
the power supply cables to the chassis.
5 Disconnect the power supply from the chassis and connector panel (two chassis screws and
three external screws). Lift out the power supply.
You may need to remove the DIMM to access the bottom chassis screw.
