Ask the customer if there are any specific machine functions that are noisy.2. Identify the source of the noise by exercising the machine in all modes.3. Use diagnostics to run individual components.4. Go to the relevant subsection:• Main Drives and Paper Transport• LSU• DADF• Tray 25. Refer to Possible Causes and Potential Solutions.Main Drives and Paper Transport• Enter dC330 code 04-100 to run the main BLDC motor. The following components will berun.– The print cartridge, PL 9.10 Item 1.– The registration roll PL 8.25 Item 3.– The registration roll idler PL 8.25 Item 17.• While the main BLDC motor runs, stack the code 08-810 to energize the tray 1 pickupsolenoid and run the tray 1 pickup roll, PL 10.22 Item 14 and feed roll, PL 10.22 Item 9.• While the main BLDC motor runs, stack the code 08-850 to energize the registration sole-noid and run the registration roll, PL 8.25 Item 3 and registration roll idler, PL 8.25 Item17.• While the main BLDC motor runs, stack the code 08-800 to energize the bypass feedsolenoid and run the bypass pickup roll, PL 7.10 Item 28.• Enter dC330 code 04-300 to run the duplex motor.
