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 reached. 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.

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/J413A-2 decreases from

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 contacts 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/J419A
and
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.
Y
N
Go to
Flag 3
on BSD 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.

Replace the IOT Drive PWB
Check for obstructions or damage that would cause the Web CRU Sensor status to be
blocked (H). There are no obstructions and/or damage.

Go to
Flag 4

OK, replace the IOT Drive PWB
Go to
Flag 5
on BSD 10.5 and check the harness for an open circuit. If the harness is OK,
