3.1.3 Isolating the Faulty Part according to the Phenomenon
Refer to this section if you could not solve the problem in Section 3.1.1.1
or Section 3.1.2 or need more information to isolate the cause according
to the exhibited phenomenon. This section mostly covers the problems
relating to the main control circuit and other parts.
Table 3-11. Phenomenons Exhibited

Step
Checkpoint
Action
1 Getting
ready
for checking
waveforms.
Using an oscilloscope, check the outputwaveform at
CN14 (CR motor connector) on the main board. For
checking, press the Load/Eject button to drive the CR
motor.
NOTE:
Be sure to disconnect the CR motor cable.
NOTE:
Ground one of the probes to the frame. The
connector itself has no ground line since the
CR motor is a bi-polar motor.
2 Checking
the
waveforms to
solve the
problem.
Drive the CR motor and check that the waveform
shown below is output from each pin of CN14.
• If the waveform appears as shown, replace the CR
motor.
• If not, replace the main control board or the CR
motor driver IC (IC18).
