LL.91 Undertoned Fault RAP
NOTE:
RAP.
Refer to BSD 9.7 while using this
The status code LL.91 is displayed when the
logic detects that the toner concentration is
significantly less than the Control Point value.
The Toner Control System is designed to
maintain the Toner Concentration within an
acceptable operating range. The Control Point
operating range is from 5.2 to 6.0 VDC. The
Toner Sensor continuously senses the Toner
Concentration. A change in the Toner
Concentration results in a corresponding
change of the Sensor signal. As the Toner
Concentration decreases, the Toner Sensor
signal voltage increases. The logic monitors
the Toner Sensor signal.
LL.91 indicates that the logic detected that the
toner concentration decreased greater than
the allowable limit.
The problem may occur if there is a problem
with the toner dispensing or the developer
mixing systems.
initial Actions
• Examine the Toner Cartridge to ensure
that the Cartridge is not empty and is
installed correctly.
« Check the Cartridge for damage and
ensure that the seal is secured to the
Cartridge in the correct location.
• Ensure that the Developer Drive Coupling
is in good condition and is engaged fully
(Figure 1).
• Ensure that the Developer Housing Auger
and Drive Gears are not damaged and are
installed correctly (Figure 2).
• Check that all the connectors between the
Toner Sensor, A22Q1, and the Main
PWB, A2, are seated correctly.
Procedure
With the printer in an LL.91 fault condition,
enter diagnostic code [9-22] and press Yes, in
order to enable the printer to function with an
LL.91 fault condition. Enter the code [0361] in
order to exit the diagnostics mode.
Make 3 test prints [9-55 Pattern 5].
The Developer Housing Auger and Drive
Gears are rotating as the prints are being
made.
Y N
I Refer to BSD 4.3, Drum Drive, to repair
I the drive circuit.
The LL.91 code is displayed as the prints
are being made.
Y N
