Table 3-22. CR Motor Does Not Work
Table 3-23. PF Motor Does Not Work
Problem
Solution
Is the CR motor
defective?
Is the CR motor
driver on the
main board
defective?
The connector for the CR motor is indicated in the figure below.
Using an oscilloscope, check the waveform for each phase as
shown. Press the Load/Eject button cause the printer try to
produce the waveform and make the carriage move.
NOTE: Ground one of the probes to the shield plate on which
the board is mounted. Note that the connector itself has
no ground line since the CR motor is a two-phase motor.
The output waveform should
be as shown at right. If the
waveform appears as
shown, replace the CR
motor. Otherwise replace
IC12 (the CR motor driver) or
the C265 Main board.

The connector for the PF motor is indicated in the figure below.
Using an oscilloscope, check the waveform for each phase as
shown. Press the Load/Eject button to cause the printer try to
produce the waveform and feed paper.
NOTE: Ground one of the probes to the shield plate on which the
board is mounted. Note that the connector itself has no
ground line since the PF motor is a two-phase motor.
The output waveform should be
as shown at right. If the
waveform appears as shown,
replace the PF motor.
Otherwise replace IC11 (the PF
