Solution
Symptom : The pump does not operate normally.
The pump motor does
not operate normally.
Sub gate array IC6
is defective.
Check the waveform for one of the
following signals output from the
IC18:
PUA0/1 (Pin1/2)
PUB0/1 (Pin23/24).
Pin 18 on the IC18
Pin 24 on the IC18
Waveform (11)
Replace the MAIN
board.
IC18 is defective.
Check the waveform for one of the
following signals from the IC18:
A (Pin 6), /A (Pin 3)
B (Pin 18) /B (Pin 21)
(Refer to the waveform (11).)
Replace the MAIN
board or IC18.
The pump motor is
defective.
Check if the resistance of the motor
coil is as follows;
7.7
Ω
± 10 % at 25°C
(Refer to Table 5-1.)
Symptom : The printer does not perform Self-test.
Sub gate array IC6
is defective.
Run the Self-test and check the
waveforms for the signals SBDATA
(Pin 24) and SCDATA (Pin 24)
output from the IC22:
Pin 24 on the IC22
Pin 18 on the CN21
Waveform (12)
Replace the MAIN
board.
CPU is defective.
Replace the MAIN
board.
Common driver IC
22 and IC23 are
defective.
Check the common signal
waveform output from one of the
following pins:
CN21:Pin 18, 19, or 20
CN18:Pin 20, 21 or 22
(Refer to the waveform (12).)
Replace the MAIN
board or IC22 and
IC23.
Fuse is blown.
Check the continuity of the fuse F1
on the MAIN board.
Replace the MAIN
board or the fuse.
Printhead is
defective.
Replace the
printhead.
CAUTION
EEPROM must not be replaced alone.
