How to Troubleshoot Abnormal Noise Issues on the C2660dn / C2665dnf / C3760n / C3760dn / C3765dnf Dell Laser Printers

If an abnormal (banging, grinding, screeching, etc) noise is present when you power on the printer there may be several components that can cause this.

In many case it could be as simple as a consumable item (such as Toner, Imaging Drum, Waste Toner Box, Fuser Assembly, or Transfer Belt) being damaged or needing reseating, Alternatively, there could be a faulty internal motor or solenoid.

To diagnose an abnormal noise issue, please start with the following steps:

1. Turn off the printer, reseat the consumable components (toners, imaging drums, transfer belt, waster toner box, and fuser) and check for any obvious damage to those components.
2. Replace the consumables with known good consumables from another printer or spare stock.
3. If no known good consumables are available, these can be removed in order to slowly turn the gears by hand and listen for any abnormal sounds.

If there is no obvious sign of damage to the consumable components, they have been reseated, and the abnormal noise is still present, please continue troubleshooting by running diagnostics on the printer's internal motor/clutches using the following steps:

1. To run noise diagnostics on the C2660dn, C2665dnf, C3760n, C3760dn and C3765dnf printers, you must boot into CE Mode. Instructions to enter CE Mode can be found here.
   Note: The LVPS must be turned on in order for the motor tests to properly run. Set the LVPS 24V (041-001) to EXEC first using the Select (Checkmark) button before executing any motors.
2. Scroll Down to 071 001: Main Motor and press Select (Checkmark) to change from Ready (OFF) to Exec (ON)- You should now hear the main Motor.
3. Leave the Main Motor at EXEC and scroll down to the following clutches/solenoids and turn on each in sequence, ensuring you stop each test before starting the next using the Cancel (X) button:
   • 071 007 MSI Feed Solenoid
   • 071 011 Exit Clutch
   • 071 012 Exit Clutch2

   • 071 021 Option Feeder2 Feed Clutch
   • 071 022 Option Feeder1 Take Away Clutch
   • 071 023 Option Feeder2 Take Away Clutch
4. Each time you should hear a click as the clutch is turned on.
5. If the abnormal sound is apparent when one of the Clutches is turned on, please take note of the number (such as 071 013) and contact Dell technical Support to advise of a technical fault.

If there is no apparent abnormal noise when activating the individual clutches/solenoids, please continue testing each motor separately from the list below, ensuring you stop each test before starting the next using the Cancel (X) button.
