Table 3-14. Pump/ASF Motor does not Operate

Step

Check Point

Action

1

Getting ready for
inspecting
waveforms.

The CN7 for the Pump/ASF motor is located on the
Main Board. Using the oscillo scope, check the
waveform for each phase output from the indicated
connector. To check the waveform, press the Load/
Eject button to attempt the ASF paper feeding. Be sure
to leave the cable for the Pump/ASF motor connected.

NOTE:

The GND can be output by placing the probe
of the oscillo scope to the tapped hole in the
bottom plate on the board with a screw. Note
the connector has no ground line since this
printer drives the motor with the bipolar
system.

C298Main Board

2

Check of the
waveform and
remedies.

While trying to drive the Pump/ASF motor, the
waveform output from each phase should be as shown
below. If the waveforms output from each phase are as
shown below, replace the Pump/ASF motor. If not,
replace the IC12 (Pump/ASF motor driver IC) or C298
Main Board.

The GND can be output by placing the probe of the
oscillo scope to the tapped hole in the bottom plate on
the board with a screw.
