The IIT Driver PWB detected a control error caused by an Exposure Lamp power failure.
Initial Actions
Refer to BSD 6.1 and BSD 6.7 in the following procedure.
Procedure
Enter dC330 006-002 ITT Exposure Lamp. Press Start. The Exposure Lamp lights.
YN
+5VDC is measured between P/
J524 -1
and GND on the IIT Driver PWB.
YN
Go to Fl
ag 7 on BSD
6.1 and check the wire. If the wire is OK, replace the Pre IPS
PWB (PL 3.5).
0 VDC is measured between P/J534-3 an
d P/J534-2 on the Lamp Ballast.
YN
Go to Fl
ag 9 on BSD 6.
1 and check the wires for an open or short circuit. If the wires
are OK, replace the IIT Driver PWB
Set the DMM to max recording mode (+ peak hold). +5VDC is measured between P/
J524-2 a
nd GND on the IIT Driver PWB.
YN
Go to Fl
ag 8 on BSD 6.
1 and check the wires for an open or short circuit. If the wires
are OK, replace the Pre IPS PWB (PL 3.5).
Set the DMM to max recording mode (+ peak hold). +5VDC is measured between P/
J534-6 and P
/J534-2 on the Lamp Ballast PWB.
YN
Go to F
lag 10 on BSD 6.1 and check the wire for an open or short circuit. If the wire
is
OK, replace the IIT Driver PWB (PL 3.2).
+24VDC is measured between P/J534-5 and
P/J534-2 on the Lamp Ballast PWB.
YN
Go to Fl
ag 11 on
BSD 6.1 and check the wires for an open or short circuit. If the
wires are OK, replace the IIT Driver PWB (PL 3.2).
Replace the Flash Lamp Ballast PWB (PL 3.
4) if the problem continues, replace the
Exposure Lamp (PL 3.4).
If the Fault continues, perform the following:
• Ensure that the connectors are fully seated.
•Go to Flag
7, Flag 8, Flag 9 and Flag 10 on BSD 6.1 and check the wires for damage.
• Replace the following in order:
– Exposure Lamp (PL 3.
4)
– Lamp Ballast PWB (PL 3.4)
–
IIT Driver PWB (PL 3.2)
– Pre IPS PWB (PL 3.
5)
6-389 Carriage Overrun Fail (Scan End) RAP
The IIT Regi (Registration) Sensor detected an overrun during Full Rate Carriage scanning.
Procedure
Go to the 6-361 Scan Initialize Regi Sensor Failure RAP.
