Initial issue
Status Indicator RAPs
6-390 Carriage Over Run Left
The carriage has overrun at the Home End.
Procedure
Switch the power off. Remove the Platen Glass (REP 6.2). Manually move the Full Rate Car-
riage. The carriage moves easily.
YN
Repair as required (PL 18.5).
Switch the power on. Enter dC330 [006-212] and select Start. Manually move the Full Rate
Carriage to the left until it stops, then move it to the right about 6 inches. The display
changes.
YN
Switch the power off. Remove the IPS Cover (PL 18.3). Enter dC330 [006-212] and select
Start. Manually move the Full Rate Carriage to the left until it stops. The display indi-
cates Hi.
YN
Go to Flag 2. Check the wire for a short circuit to GND. If the wire is good, replace
the IIT Registration Sensor (PL 18.4).
+5 VDC is measured between P/J722-B3 and P/J722-B1 on the IIT/IPS PWB.
YN
Replace the IIT/IPS PWB (PL 18.3).
Move the Full Rate Carriage to the right about 6 inches. Less than +1.0 VDC is mea-
sured at P/J722-B2 to GND.
YN
Go to Flag 1 and Flag 2. Check the wires for an open circuit. If the wires are good,
replace the IIT Registration Sensor (PL 18.4).
Replace the IIT/IPS PWB (PL 18.3).
Manually move the Full Rate Carriage to the left until it stops. Enter dC330 [006-005] (Scan)
and select Start. The Carriage Motor energizes.
YN
+24 VDC is measured at P/J725-1 and -2 on the IIT/IPS PWB.
YN
Replace the IIT/IPS PWB (PL 18.3).
NOTE: In the next step, two of the four pins on P/J725 should measure at least +24 VDC.
The other two will measure approximately +2 to +4 VDC.
+24 VDC is measured at two of the following pins on P/J725: 3, 4, 5 or 6.
YN
Go to Flag 3 and Flag 4 and check the wires for an open circuit. If the wires are
good, replace the Carriage Motor (PL 18.5).
Replace the IIT/IPS PWB (PL 18.3).
