The Carriage Motor error was detected after the initialization was started.
Procedure
BSD 6.4 BSD 6.1
Turn off the power. Remove the following covers:
ïTOP COVER
ï IIT REAR COVER
Measure conductivity of the following:
Between the Carriage Motor p739-6 and the IIT/IPS PWB j725-6
Between the Carriage Motor p739-6 and the IIT/IPS PWB j725-5
Between the Carriage Motor p739-4 and the IIT/IPS PWB j725-4
Between the Carriage Motor p739-3 and the IIT/IPS PWB j725-3
Between the Carriage Motor p739-2 and the IIT/IPS PWB j725-2
Between the Carriage Motor p739-1 and the IIT/IPS PWB j725-1
The resistance is 1 Ohm or less for all wires.
YN
Check wires with more than 1 Ohm for an open circuit or poor contact.
Replace the Carriage Motor (PL 18.5).
If the problem continues, replace the IIT/IPS PWB (PL 18.3)
