How/where to check
1
Does the same symptom occur after
turning OFF and ON the scanner?
Press power button of the scanner for more than 2 seconds to
turn it OFF, and after more than 2 seconds elapse, press the
power button to turn the scanner ON.
2
Does any foreign object get inside the
Control PCA?
Take out the Control PCA for checking (Refer to
Section
4-7-3
).
3
Are the cables between Control PCA and
LF motor, PICK motor or BW motor
damaged? Or are the connectors
connected correctly?
Refer to
Section 4-9-6
for checking LF motor cable.
Refer to
Section 4-10-7
for checking PICK motor cable.
Refer to
Section 4-10-8
for checking BW motor cable.
4
Are coil resistances of LF motor, PICK
motor, or BW motor normal?
Remove PCB unit by referring
Section 4-7-3
, and check the
coil resistances between the following pins of connector.
For LF motor and PICK motor:
Resistance (5) - (1), (5) - (2): 4.2
Ω ±10%
Resistance (6) - (3), (6) - (4): 4.2
Ω ±10%
Resistance (1) - (2), (3) - (4): Approximately 8.4
Ω
Other match:
∞ Ω
For BW motor:
Resistance (5) - (1), (5) - (2): 20
Ω ±10%
Resistance (5) - (3), (5) - (4): 20
Ω ±10%
Resistance (1) - (2), (1) - (3): Approximately 40
Ω
Resistance (1) - (4), (2) - (3): Approximately 40
Ω
Resistance (2) - (4), (3) - (4): Approximately 40
Ω
Replace the motor, if the resistance does not meet the above.
5
Replace Control PCA and see if the error
is resolved.
Refer to
Section 4-11
for replacement.
