Status Indicator RAPs
09-310, 09-390 Low Toner Sensor Failure RAP
09-310 The toner cartridge motor continues to dispense toner for a period greater than 12 sec-
onds after the low toner sensor detects that the toner dispense module is full.
09-390 The low toner sensor detects that the toner level is low for a period greater than 70 sec-
onds after toner cartridge motor start.
Initial Actions
Figure 1. Ensure the toner cartridge is not empty. If the toner cartridge is empty, install a new
toner cartridge, (32-55 ppm) PL 9.17 Item 4, (65-87 ppm) PL 9.15 Item 4.
Procedure
NOTE: The door interlock switch must be cheated when ch24V components.
NOTE: The toner cartridge motor will time out after 5 seconds.
Cheat the door interlock switch. Enter dC330 code 09-045 toner cartridge motor, MOT09-045.
Press start. Observe the toner cartridge. The toner cartridge rotates.

Go to Flag 1. Check MOT09-045. Refer to:
• GP 10 How to Check a Motor.
• Figure 2.
• P/J6, IOT PWB.
• 01G +24V Distribution RAP
• 01B 0V Distribution RAP.
Install new components as necessary:
• Toner dispense module, (32-55 ppm) PL 9.17 Item 1, (65-87 ppm) PL 9.15 Item
1.
• Developer assembly, (32-55 ppm) PL 9.17 Item 2, (65-87 ppm) PL 9.15 Item 2.
• Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed,
PL 1.10 Item 2.
Figure 1 and Figure 2. Check the toner dispense drive gears.
If necessary install a new toner dispense module, (32-55 ppm) PL 9.17 Item 1, (65-87
ppm) PL 9.15 Item 1.
Enter dC330 code 09-040 toner dispense motor and add the code 09-310 low toner sensor,
Q09-310. Press Start.
NOTE: It may necessary to enter the codes several times to ensure that the toner dispense
motor does actuate and deactuate the low toner sensor. It may be necessary to make several
copies to prevent over toning the developer.
The display changes from high to low or low to high.

Figure 2.
• P/J6, IOT PWB.
• 01B 0V Distribution RAP.
• 01E +5V Distribution RAP.
Install new components as necessary:
• Low toner sensor, (32-55 ppm) PL 9.17 Item 5. (65-87 ppm) PL 9.15 Item 5.
• Developer assembly, (32-55 ppm) PL 9.17 Item 2, (65-87 ppm) PL 9.15 Item 2.
• Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed, PL
1.10 Item 2.
The fault may be intermittent, due to toner bridging inside the toner cartridge. Install a new
toner cartridge, (32-55 ppm) PL 9.17 Item 4, (65-87 ppm) PL 9.15 Item 4.
