Low Toner RAP
(Low Toner Lamp is
Lit)
The status code J, with the Low Toner lamp
on, indicates the toner concentration is
significantly lower than the nominal set
point.
This status code may occur i f there
is
a
problem with toner dispensing or the mixing
of the developer material. The Initial Actions
deal with the most likely mechanical causes
for
this
problem.
Initial Actions
Ensure that the toner cartridge i s the
correct cartridge, and
is
installed
correctly.
Ensure that the green clip on the
right end of the cartridge i s not
deformed or stretched.
Remove the cartridge. Ensure the
plastic flap is
4
mm off the cartridge.
Shake the toner cartridge from left
to right to ensure the mixture is free
and the cartridge is not empty.
Check that the pick-off baffle (REP
9.9)
is installed correctly with the
straight edge of the baffle touching
the magnetic roll with the label
down.
Ensure that the Toner Dispense
Solenoid is adjusted correctly (ADJ
9.5).
Ensure that when the toner
cartridge is rotated one revolution,
the toner is deposited evenly on the
surface of the developer material
Ensure that the Toner Solenoid
connectors
P/J 31, P/j 35, P/j
18 are
connected and fully seated.
Ensure that the Toner Sensor
connector P/J 34 is connected and
fully seated.
Ensure that the level of the
developer material is above auger.
Ensure that the developer housing
is
level side-to-side and front t o rear.
Ensure that the auger gutter i s on
the gutter pin if not, install the
Developer Gutter Clip (PL 9.5).
Ensure that the reclaim bottle is not
full. A full bottle may indicate a
developer system problem. Refer
t o
the OF2 High Toner Consumption
RAP.
CAUTION

To
prevent
damage to the drive gears; before
entering any diagnostic test which
requires the use of the main drive
motor (A); always enter the codes (g)
fuser and (1) cooling fans first, and then
allow the copier to operate for at least
2 minutes. Then press code {A) to start
the main drive motor.
Procedure
Enter diagnostic codel41 and note the
setting. Press Stop.
WIO TAGS 2,7, or 89; enter the diagnostic
codes
[g, J ,
and
A
I,
W/ TAGS 2,7,
or

enter the codeIA]
.
WARNING
There will be a time delay between the time
the code [A] i s entered and the time the
motor starts to turn,
Tho
motor
wlll
not
start until the fuser is at the correct
temperature.
Enter the code
[dl,
Toner Dispense Solenoid.
Enter the code [YJ, toner concentration
control point value.
NOTE: Once diagnostic code [YJ
is
entered
further chaining is not allowed.
The value displayed in code
[Y]
is
3
levels
below the control point value displayed in
Diagnostic Code
141.

Replace the Control PWB. (REP 3.1).
Switch off the copier. Switch on the copier
an allow it to cycle out (approximately
8
minutes). If te J-Low Toner does not clear,
proceed with this RAP.
Make 3 copies of 82E5980
in
the Normal
copy mode. Check the image density of the
last copy.
The density of the 0.7065 paragraph in the
center of 82E5980
i s greater than or equal to
paragraph 28.5 on S.1.R 82E7030.
