10-422 Web CRU RAP, 10-500 Fuser Web CRU Not
Status Indicator RAPs
Reissue
10-422 Web CRU RAP
A faulty connection has occurred between the Web CRU and the IOT Drive PWB.
NOTE: A legitimate Fuser Web Near Empty Condition occurs when 1458 minutes of Web On
Time has been reac
hed. The machine issues a warning when it detects Fuser Web Near
Empty. With a legitimate “Web Near Empty” condition, only a message is displayed, not a fault
code.
NOTE: This status code is stored in NVM location 777-077 and cannot
be
reset by Power Off/
On. To reset this code, enter Diagnostics and change the value in NVM location 777-077 Web
Status from “1” to “0”.
Initial Actions
Refer to BSD 10.5 and 10.12 for the following procedure.
Perform the following:
1. Open the Drawer.
2. Remove and inspect the Web CRU. If the web supply roll
is near empty, then replace it
and proceed to the next step.
3. Remove the Oil Cartridge (PL 8.
1).
4. Remove the Front Cover (PL 8.1).
5.
Close the Drawer.
6. Switch the power Off, then On.
Procedure
+24 VDC is measured between P/J413A-2 on the IOT Drive PWB and GND.
YN
+24 VDC is measured between P/
J440-1
on the Web Drive PWB and GND.
YN
Go to Fl
ag 1 on BSD
10.5 and check the harness for an open circuit. If the harness is
OK, replace the Distribution PWB (PL 9.3).
+24 VDC is measured between P/J440-2
on the Web Drive PWB and GND.
YN
Check the Web Motor (PL 8.
4) f
or an open circuit. If it is OK, replace the Web Drive
PWB (PL 8.4).
Go to Flag 2 on BSD
10.5 and check the harness for an open circuit.
Enter DC330 010-032 Web Motor. Press Start. The voltage at P/J41
3A-2 decreases from
+24 VDC to less than +1.0 VDC.
YN
Replace the IOT Drive PWB (PL 9.
2).
Install the Web CRU, Front Cover and Oil Car-
tridge.
Replace the Web Drive PWB (PL 8.4).
If that does not correct the problem, replace the Web
Motor (PL 8.4).
10-500 Fuser Web CRU Not Present RAP
The Web CRU detection circuit detected that the CRU was not present or was not fully seated.
NOTE: This condition occurs when the Web CRU is not installed, or is not seated fully. It will
also occur if
the small 3-pin connector (under the oil bottle) is not connected when the Fuser
Assembly is installed.
Initial Actions
Refer to BSD 10.5 and 10.12 for the following procedure.
NOTE: Before proceeding into this procedure, clean the cont
acts on the CRU connector. Oxi-
dation on the connector has been known to cause this problem
. Also try reseating the CRU
several times to see if the problem remains.
Ensure that connectors P/J
419A and P/J722 are seated correctly on the IOT Drive PWB, Web
CRU Sensor and there are no obvious crimped or broken wires.
Procedure
Enter dC330 010-223 Web CRU Home. Press Start. The Web CRU status signal is H.
YN
Go to Fl
ag 3 on BS
D 10.5 and check the harness and connectors for a short circuit to
GND. If the harnesses and connectors are OK, replace the Web CRU.
Press Stop.
Power Off. Remove the Fuser Web CRU. Enter dC330 010-223 Web CRU Home.
Press Start. The Web CRU Sensor status is L.
YN
Install the Fuser Web CRU. +5 VDC is measured between P/
J419A-17 and
GND.
YN
Replace the IOT Drive PWB (PL
9.
2).
Check for obstructions or damage that would cause t
he Web CRU Sensor status to be
blocked (H). There are no obstructions and/or damage.
YN
Remove the obstructions and/or damage.
+2.2 VDC is measured between P
/J419A-
16 and GND.
YN
Go to F
lag 4 on BSD 10.5 and check the harness for an open circuit. If the harness is
OK
, replace the IOT Drive PWB (PL 9.2).
Go to Flag 5 on BSD 10.5 and check the harness for an open circuit. If the harness is OK,
replace th
e IOT Drive PWB (PL 9.2).
Check for obvious damage, missing and/or broken F
user Web Drive gear assemblies. Install
the Fuser Web CRU.
