3. Points to Note When Handling the
Composite Power Supply PCB
1) Some capacitors on the composite power
supply hold charges when the machine’s
power supply is off.
Take extra care never to short the termi-
nals of the capacitor whenever you have
removed the composite power supply
PCB.
2) When handling the PCB, hold its heat ra-
diating plate (at the center) or its both
edges. In particular, keep in mind that
holding the area indicated by “
” can
cause deformation or cracking of the
board.
