Common
pin No.
Test pin
No.
Test method
Normal value
CN4
(CR motor)
5,6
1,2,3,4
Place 1 lead on pin 5 or pin 6,
and set the other on each
terminal of the 4 phases.
Approximately
1.1
(at 25° C)
CN4
(PF motor)
17
13,14,
15,16
Place 1 lead on pin 17, and set
the other to each terminal on the
4 phases.
Approximately
5.0
(at 25° C)
CN4
(PG motor)
7,8
9,10,
11,12
Place 1 lead on pins 7 and 8, and
set the other on each terminal of
the 4 phases.
Approximately
250
(at 25° C)
CN3
(Ribbon motor)
7
8, 9,
10, 11
Place 1 lead on pin 7, and set the
other to each terminal on the 4
phases.
Approximately
76
(at 25° C)
Table 5-6. Printhead Driver Test Point
Transistor No.
Test method
(With the printer power off, and set the
multimeter to
or diode check mode.)
Meter reading
Q6 to Q33
Connect the leads to the base and collector
or emitter, then reverse the lead.
Neither open or close
completely.
Table 5-7. Sensor Test Point
Sensor connector
No.
Test method
(With the printer power off, and set the
multimeter to
or diode check mode.)
Meter reading
CN3
(Color ribbon
cartridge sensor)
Place 1 lead on pin 13 and the other on the
ground; then install the color ribbon cartridge
to the CR unit.
Meter should toggle
between open and
short.
CN3
(Rear paper sensor)
Place 1 lead on pin 16 and the other on the
ground; then activate the sensor actuator.
Meter should toggle
between open and
short.
CN5
(PGHP sensor)
Place 1 lead on pin 22 and the other on the
ground; then activate the sensor actuator.
Meter should toggle
between open and
short.
CN5
(Release sensor)
Place 1 lead on pin 20 and the other on the
ground; then change the release lever setting.
Meter should toggle
between open and
short.
CN5
(Adjust switch)
Place 1 lead on one of the pins from 9 to 12
and the other on the ground; then change the
adjust switch setting.
Meter should toggle
between open and
short.
CN14
(Interlock switch)
Place 1 lead on pin 1 and the other on the pin
2; then open and close the printer cover.
Meter should toggle
between open and
short.
