09-360, 09-361, 09-362, 09-363 Toner Concentration Sensor
Failure RAP
09-360 The toner concentration sensor has registered a reading outside the range, +0.75V to
+4.55V for three consecutive sheets.
09-361 The toner concentration sensor is reading high. This indicates that the toner concentra-
tion (TC) is low.
09-362 The toner concentration sensor is reading low. This indicates that the toner concentra-
tion (TC) is high.
09-363 This code is generated by the following factors:
• The developer is not positioned correctly against the xerographic module.
• The toner concentration is low.
• The machine is being installed.
• On the fifth consecutive occurrence.
GUI message - TONER CONTROL FAILURE
Initial Actions
• Check developer roll area for toner and bead contamination. If necessary, go to IQ1
Image Quality Entry RAP.
• If 09-360 fault, enter dC131 location 09-115, sensor failure lockout flag. Check that it is
set to '0'. If set at '1' the toner dispense motor will not run.
• If 09-361 fault, enter dC131 location 09-001 TC lockout low. Check that it is set to '0'. If
set at '1' the toner dispense motor will not run.
– Check that when the xerographic module latch is in the locked position, the devel-
oper module is correctly installed, REP 9.2.
• If 09-362 fault, enter dC131 location 09-276 TC lockout high. Check that it is set to '0'. If
set at '1' the toner dispense motor will not run
• Switch off the machine, then switch on the machine, GP 14.
Initial Procedure
Make 20 prints. If the following three conditions apply, go to the 09-310, 09-390 Low Toner
Sensor Failure RAP. If not continue at the Procedure.
1. The prints or copies are faint.
2. The toner cartridge is not rotating.
3. The low toner sensor, 09-310, reading is high.
Procedure
NOTE: The door interlock switch must be cheated when checking +24V components.
Go to Flag 1 and read the voltage at P/J93 pin 8. The voltage is outside the range of +0.7V
to +4.5V.

Check the steps that follow:
• Check the wiring, GP 7, between P/J93 to P/J6 on the IOT PWB.
• Refer to the 01B Ground Distribution RAP.
