Status Indicator RAPs Initial issue
9-413 Toner Cartridge (K) Near Empty
The Black Toner Cartridge is nearly empty. This fault requires service only if the message
appears before the Toner Cartridge is depleted.
NOTE: Continuous running of high density prints can temporarily deplete the toner supply.
Initial Actions
• Ensure that there is toner and the toner is evenly distributed in the cartridge (K).
• Check the ATC Sensor (K) for blockage or contaminants.
• Check the drive system from the Main Drive Motor to the Developer Housing (K) for dam-
age.
Procedure
Enter dC330 [009-004] and press Start . The Toner Dispense Motor (K) energizes ( PL 6.1 ).
Y N
Go to Figure 1 . There is +24 VDC from P/J533 -A8 to GND.
Y N
Go to the +24 VDC Wirenets ( Figure 2 ) and troubleshoot the problem.
There is +24 VDC from P/J533 -A7 to GND.
Y N
Check the wires from P/J533 to P/J230 for an open circuit. If the wires are OK,
replace the Cyan Toner Dispense Motor ( PL 6.1 ).
Enter dC330 [009-003]. The voltage from P/J533 -A7 to GND drops to less than 1
VDC.
Y
N
Replace the MCU PWB ( PL 13.1 ). If the problem continues, replace the I/F PWB ( PL
9.1 ).
Check the wires from P/J533 to P/J230 for an open circuit. If the wires are OK, replace the
Cyan Toner Dispense Motor ( PL 6.1 ).
The machine is a DC3535.
Y
N
Enter dC330 . Stack the codes [004-004, Main Motor] and [009-013, Dev. Clutch (K)] and
press Start . The Black Developer Assy. energizes ( PL 1.1 ).
Y N
Go to Figure 2 . Check the circuit of the Developer Clutch (K) ( PL 1.2 ).
Refer to BSD 4.1 ( Figure 1 ) Check the mechanical drive to the Clutch.
Check ADJ 9.3 . The ATC Sensor (K) fail judgement is OK.
Y N
Go to the 9-383 , ATC Sensor Failure (K) RAP.
After checking that no failures are detected during normal operation, go to call closeout.
Enter dC330 . Stack the codes [004-004, Main Motor] and [009-013, Dev. Clutch (K)] and press
Start . The Black Developer Assy. ( PL 1.1 ) energizes.
Y N
Go to Figure 3 . Check the circuit of the Developer Clutch (K) ( PL 1.2 ).
Refer to BSD 4.1 ( Figure 1 ). Check the mechanical drive to the clutch.
Check ADJ 9.3 . The ATC Sensor (K) fail judgment is OK.
Y N
Go to the 9-383 ATC Sensor Failure RAP.
After checking that no failures are detected during normal operation, go to call closeout.
