JA REPLACE OIL/PAD RAP
The Oil/Pad needs to be replaced.
INITIAL ACTION
Check the Oil Bottle and sump. If required,
replace the Wiper Roll and Oil Bottle. If this
code persists after a new Oil Bottle is installed
or the Oil is OK, continue with this RAP.
Paper
dust and other contaminants can cause
the fuser oil to get cloudy and solidify causing
the ball that triggers the Low Oil Sensor to
stick. When low oil is detected, the printer will
stop and the fuser will be powered off after 50
prints to prevent Fuser damage. If the fuser
has the contamination described above, the
ball could be stuck in a position that will
prevent the fuser from warming up.
Check to ensure the fuser sump has oil in it.
There have been some reported instances of
defective oil bottles failing to dispense oil into
the sump.
Ensure that the valve stem on the oil bottle is
not bent or off center. A bent stem will not
engage the plunger in the sump correctly.
If the sump is full, check to see if the ball is
stuck in the bottom of the channel. If it is, you
may be able to correct the problem by
removing the rubber stopper in the tank above
the ball and using a scribe or screwdriver to
loosen the ball.
NOTE: This is only a temporary fix. You
should have the customer order a new fuser
assembly. If in your judgment this is a
premature failure, follow the applicable
warranty replacement procedures.
If the problem still exists continue with this
RAP.
PROCEDURE
Enter IOT normal diagnostics. Scroll to the
SWITCH SCAN program and select Scan Row
05. Press
Form Feed [1]
.
Open the Printer and remove the Fuser
Assembly.
Actuate and deactuate the Oil Sensor while
observing the Cyan LED.
The Cyan, LED switches off and on.
Y
N
With Scan Row 05 still selected, actuate
and deactuate the Cleaner Jam Switch
while observing the Magenta LED.
The Magenta, LED switches off and on
.
Y
N
Refer to BSD 10.4 and check the
Strobe 1 signal CN103-19 for an open.
If no open exists replace the PCU
PWB.
Refer to BSD 10.4 and check the Oil Low
signal, +5 VDC and GND CN309-2, 1, 3
for an open.
If no open exists, replace the PCU PWB.
If the problem still exists, replace the Oil
Sensor.
Check the ball that actuates the Oil Sensor to
ensure that it is moving freely. Reinstall the
Fuser Assembly and close the printer to see if
the fault clears.
If the problem still exists replace the Wiper
Roll and Oil Bottle. If the problem still exists,
replace the PCU PWB.
T0 THERMISTOR ERROR RAP
The Fuser Thermistor readings are out of
range, the Fuser is missing, or the Fuser is not
seated correctly.
INITIAL ACTION
NOTE: During the following check be careful
not to tip the Fuser.
Remove the Fuser Module and check the
condition of the Fuser Connectors.
Check the operation of the shutter that covers
the fuser connectors.
Reinstall the Fuser Module.
Switch the power off wait 10 seconds and
switch the power on. Recheck for the fault.
PROCEDURE
Set up the meter to read +5 VDC. Measure
between CN103-9 (+) and ground (
−
).
When the fuser is cold, the reading should be
around 0.1 VDC. When the fuse is hot, the
reading should be approximately 3.5 VDC.
The readings are OK.
Y
N
Go to BSD 10.5 in Section 7 and trouble-
shoot the Fuser Thermistor signal and
+5 VDC for an open or a short to ground
(CN103-9, CN306-3, 2).
If the wiring is OK, replace the Fuser
Assembly. If the problem still exists,
replace the PCU PWB.
Replace the PCU PWB.
