9-930 Black Drum Cartridge Not Detected
The machine logic detected that Black Drum Cartridge is not installed.
Initial Actions
• Ensure Black Drum Cartridge is installed correctly.
• Switch the power off, then on.
Procedure
Swap Black Drum Cartridge with Drum (Y), (C) or (M). The problem is corrected.
YN
Check that P/J405 on the MCU PWB and P/J622 are connected. Go to Figure 1 and
check the wires for an open or short. If the check is OK, replace the MCU PWB (PL 13.1).
If the problem continues, replace the ESS PWB (PL 13.1).
Replace the defective Drum Cartridge (refer to Section 6, Machine Consumables).
