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 if 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
is
the
correct cartridge, and
is
installed
correctly.
Ensure that the green clip on the
right end of the cartridge
is
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 to rear.
Ensure that the auger gutter
is
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
to
the
OF2
High Toner Consumption
RAP.
