  54.0B, 54.0C, 54.0D, 54.0F procedure: The last two digits indicate the color (00 = black, 01 = cyan, 02 = magenta, 03 = yellow) 1. Check for correct formation of the calibration swatches on the ETB. If the swatches are light or missing a color, check the primary transfer components (cartridge, main drive assembly, HVPS) for the missing or light color. 2. Check the cartridge and replace if necessary. 3. Check connectors J4401A/J4401B on the color misregistration sensor to J1012 on the DC controller. 4. Replace the paper feed assembly. 5. Replace the DC controller.

For tray 2, verify that connector J93 on the DC controller is firmly seated. This connector is for the lift motor. 4. Verify that connector J4618 is securely connected, and then check connector J1015 on the DC controller. 5. For trays 3 and 4, verify that connectors J8226 and 8211 on the paper deck driver PCB are securely connected. 6. If a loud clicking sound is heard while the MFP restarts, reinstall the lifter motor assembly and ensure that the gears are seated properly. Also ensure that the cassette pickup roller is properly installed. If the lifter motor assembly is damaged, replace the assembly and check for any obstruction.
