Status Indicator RAPs
Reissue
9-311 Xerographic CRU (Drum) Type Mismatch RAP
Xerographic CRU (Drum) Type Mismatch. The Control Logic detected that the Xerographic
CRU (Drum) that is installed in the machine is not the correct type for this product.
Initial Actions
• Refer to BSD 9.1 and BSD 9.15 for the following procedure.
• Ensure that P/J422B on the I
OT Drive PWB, P/J713 and P/J704 on the EP ROM PWB
are connected before beginning this RAP.
Procedure
Check the Type of Xerographic CRU (Drum) that is installed in the machine, NVM 774-056
Drum Unit Type. The Xerographic CRU (Drum) is the approved type.
YN
Install an approved Xerographic CRU (Drum).
Go to Fl
ag 8 on BS
D 9.1. Check the harness for an open circuit or a short circuit. If the harness
is good, replace the Xerographic CRU (Drum). If the problem continues, replace the IOT Drive
PWB (PL 9.2).
9-342/9-432 2nd BTR Contact Fail RAP
The Control Logic has detected that the 2nd BTR failed to contact the IBT.
Initial Actions
• Refer to BSD 9.10 and 9.15 for the following procedure.
• Ensure that P/J421A and P/J414A on t
he IOT Drive PWB (PL 9.2), P/J255 on the 2nd
BTR Retract Clutch (PL 1.4), and P/J159 on the 2nd BTR Retract Home Position Sensor
(PL 7.9) are connected before beginning this RAP.
Procedure
Stack the codes dC330 004-007 Main Motor and 009-058 2ND Belt Transfer Roll Contact.
Press Start. The Main Motor energizes.
YN
Go to the O
F4-001 M
ain Motor RAP.
Enter dC330 009-215 2nd BTR H/Position Sensor. Press Start. T
he Display is (H)
YN
Press Sto
p fo
r the codes dC330 004-007 Main Motor and 009-058 2ND Belt Transfer Roll
Contact. Rotate the Indicator (Item 3 PL 7.9) to block the 2nd BTR Retract Home Position
Sensor. The display changes to (H)
YN
+5 VDC is measured between P/
J421A-2
and GND on the IOT Drive PWB.
YN
+5 VDC is measured between P
/J421A-
3 and P/J421A-1 on the IOT Drive
PWB.
YN
Go to the +5 VDC (IOT) Wirenet and check the wires between P/
J21-1 on
th
e IOT LVPS and P/J421A-3 on the IOT Drive PWB. Go to the DC COM
(IOT) Wirenet and check the wires between P/J21-5 on the IOT LVPS and
P/J421A-1 on the IOT Drive PWB.
Go to F
lag 1 on BSD 9.10 and check the wire for a short circuit to ground. Go to
Fla
g 3 on BSD 9.10. Check the wires for an open circuit. If the wires are good,
replace the 2nd BTR Retract Home Position Sensor (PL 7.9).
Check the 2nd BTR Retract Home Position Sensor for intermittent operation. If the
sens
or is good,
replace the IOT Drive PWB (PL 9.2).
Stack the codes dC330 004-007 Main Motor and 009-058 2ND Belt Transfer Roll Con-
tact. The 2nd BTR raises to the contact position.
YN
Press Stop f
or t
he codes dC330 004-007 Main Motor and 009-058 2ND Belt Trans-
fer Roll Contact. +24 VDC is measured at P/J414B-
10 on the IOT Drive PWB.
YN
+24 VDC is measured at P
/J414B-
9 on the IOT Drive PWB.
YN
Go to the +24 VDC Wirenet and check the fuse F1 on the AC Drive PWB.
I
f t
he fuse is good, check the wires between P/J24-2 on the IOT LVPS
and P/J414B-9 on the IOT Drive PWB.
