062-360 Carriage Position RAP
BSD-ON: 6.3
• An error occurred while counting the pulses of the Carriage Motor.
• After the Carriage Motor turned On, the IIT Registration Sensor did not turn On within the
specified time.
Procedure
Check the Carriage Rail for dirt or contamination or distortion. Dirt or contamination or dis-
tortion is found in the Carriage Rail.
Y N
Clean the rails or correct the distortion (PL 11.4).
Execute Component Control [062-212 IIT Registration Sensor]. Actuate the IIT Registration
Sensor with paper. The display changes.
Y N
Check the connections of P/J728 and P/J722. P/J728 and P/J722 are connected cor-
rectly.
Y N
Connect P/J728 and P/J722.
Check the wire between J728 and J722 for an open circuit or a short circuit (BSD 6.3 Flag
2/Flag 3). The wire between J728 and J722 is conducting without an open circuit or
a short circuit.
Y N
Repair the open circuit or short circuit.
Measure the voltage between the IIT/IPS PWB P722-A7 (+) and GND (-) (BSD 6.3 Flag 2/
Flag 3). The voltage is approx. +5VDC.
Y N
Replace the IIT/IPS PWB (PL 13.3).
Measure the voltage between the IIT/IPS PWB P722-A9 (+) and GND (-) (BSD 6.3 Flag
2).
Actuate the IIT Registration Sensor (PL 13.4) with paper. The voltage changes.
Y N
Replace the IIT Registration Sensor (PL 13.4).
Replace the IIT/IPS PWB (PL 13.3).
Alternately execute Component Control[062-005 Carriage Motor SCAN ON] and Component
Control[062-006 Carriage Motor RETURN ON]. The Carriage Motor starts up.
Y N
Check the connections of P/J722 and P/J721. P/J722 and P/J721 are connected cor-
rectly.
Y N
Connect P/J722 and P/J721.
Check the wire between J722 and J721 for an open circuit or a short circuit (BSD 6.3 Flag
1). The wire between J722 and J721 is conducting without an open circuit or a short
circuit.

Y N
Repair the open circuit or short circuit.
Measure the resistance of the Carriage Motor (PL 13.5). The resistance between J721-
5/6 and J721-1/2/3/4 is approx. 1Ohm.
Y N
Replace the Carriage Motor (PL 13.5).
Measure the voltage between the IIT/IPS PWB (PL 13.3) P722-B10 (+) and GND (-), and
between P722-B11 (+) and GND (-) (BSD 6.3 Flag 1). The voltage is approx. +24VDC.
Y N
Replace the IIT/IPS PWB (PL 13.3).
Replace the Carriage Motor (PL 13.5)
If the problem persists, replace the IIT/IPS PWB (PL 13.3).
Replace the IIT/IPS PWB (PL 13.3).
