Status Indicator RAPs Initial issue
9-363 Black Drum Cartridge Communication
A communication failure with the Black Drum Cartridge was detected.
Initial Actions
Check that the Black Drum Cartridge is seated correctly.
Procedure
Enter dC330 [009-154]. The display is H.
Y N
Go to Figure 1 . Check the wires between P/J405 and P/J153 . If the check is OK, replace
the Black Drum Cartridge (refer to Section 6, Machine Consumables ).
Replace the MCU PWB ( PL 13.1 ).

9-380 ATC Sensor (Y)
The ATC Sensor (Y) detects a low TC (toner concentration).
Initial Actions
• Go to the 9-410 RAP and verify the correct operation of the Yellow Dispense Motor and
the Developer Motor.
• Check that Toner/Developer is present.
• Check the ATC Sensor (Y) for contamination. Ensure that the sensor is seated correctly.
Procedure
NOTE: To clear this fault, enter dC131 and set the value of NVM location 752-109 to 0.
Record the value in NVM location 752-324, then set the value to 1. Perform ADJ 9.3 . After the
measurement has completed, restore the value. The ATC Sensor (Y) fail judgement is OK.
Y N
Refer to Figure 1 and check connector P/J129 . If the check is OK, replace the ATC Sen-
sor (Y) ( PL 6.2 ).
If the problem continues, replace the MCU PWB ( PL 13.1 ).
After checking that no failures are detected during normal operation, go to call close out.
