Condition
Cause
Checkpoint
Solution
Symptom : CR does not operate normally.
CR motor does not rotate
normally.
Sub gate array IC16
is defective.
Check the waveform for the
signals HPASEA/B (Pin 7) output
from the IC19/20.
HPASE on the IC20 (Pin 7)
OUTA on the IC19 (Pin 10)
Waveform (9)
Replace the MAIN
board or IC16.
CPU is defective.
Replace the MAIN
board.
IC19 or IC20 is
defective.
Check the the
drive waveform
for the signals
(Pin 10/15)
output from the IC19/20.
(See the waveform (9))
Replace the IC19 or
IC20.
CR motor is
defective.
Check if the resistance of the
motor coil is as follows;
5
Ω
±
7 % at 25°C per phase
(Refer to Table 5-1.)
Replace the CR motor.
Symptom : The printer feeds paper abnormally.
PF motor does not
operate normally.
Sub gate array IC6
is defective.
Check the waveform for one of
the following signals output from
the IC17:
PFA0/1 (Pin1/2)
PFB0/1 (Pin 23/24)
Pin 1 on the IC17
Pin 6 on the IC 17
Waveform (10)
Replace the MAIN
board.
CPU is defective.
Replace the MAIN
board.
IC17 is defective.
Check the wavefoarms for one of
the following signals output from
the IC17:
PFA0/1 (Pin 2/1)
PFB0/1 (Pin 23/24)
(Refer to the waveform (10).)
Replace the MAIN
board.
PF motor is
defective.
Check if the resistance of the
motor coil is as follows;
10
Ω
± 10 % at 25 °C
(Refer to Table 5-1.)
Replace the PF motor.
