Diagnosing Noise Issues on the Dell 2150cn/cdn Laser Printer

In order to diagnose any abnormal noise issue with your Laser Printer we must first rule out any consumable parts and then, if the noise is still present, carry out diagnostics on individual motors.

On the 2150cn/cdn there are several parts which could cause the abnormal noise.

Where possible it is recommended that you swap the consumable components with those from a working Printer to verify where the issue occurs.

Swapping Consumables

Please use the articles below for guides to removing the consumable components in the Printer (PHD, Fuser, Toners) as well as the optional extras.

Running Motor Tests

If you do not have another working Printer or any spare consumable items, it is still possible to try and diagnose an abnormal noise issue by testing individual motors.

To test the Motors of the Printer, we must first boot into Customer Mode

For detailed instruction on booting into Customer Mode and using its features, please see article:

Customer Mode on the Dell 2150cn/cdn Laser Printer
  • In Customer Mode, select IOT Diags

  • Select Digital Output

  • Run the Paper Feed Test from the main Paper Tray:

  • DO-0

  • DO-5

  • DO-29

  • DO-2f

  • As you turn on each motor in succession, listen out for the recurrence of the abnormal noise

If you are unable to identify the abnormal noise, please try running the other motors in the Printer:
  • DO-1: Main Motor

  • DO-5: Sub Motor

  • DO-a: K Mode SOLENOID




  • DO-1e: Fan

  • DO-21: Yellow Toner Motor

  • DO-23: Magenta Toner Motor

  • DO-25: Cyan Toner Motor

  • DO-27: Black Toner Motor

  • DO-29: Regi Clutch



  • DO-3d: Black Drum Erase Lamp

  • DO-3f: Yellow, Magenta and Cyan Drum Erase Lamp

If you have been unable to identify the abnormal noise while running the Motors individually or the noise seems to be present on more than one motor, the issue may be caused by the PHD Unit or Fuser.

In order to test this, assuming you have no spare PHD Unit or Fuser Unit, please try the following steps:
  • Remove the PHD Unit

  • Remove the Fuser Unit

  • Boot into Customer Mode

  • In 'Digital Output' run the Main Motor (DO-1) and listen for the recurrence of the abnormal noise

  • If there is no noise, stop the test and re-insert the Fuser Unit

  • Run the Main Motor again and listen for the recurrence of the abnormal noise

  • If there is no abnormal noise, re-insert the PHD Unit and run the Main Motor again

  • If the noise has returned after fitting either of the Fuser or PHD Unit, this will be the cause of the noise

  • If you have identified the cause of the noise, or need further assistance, please contact Dell via the Twitter Contact Button
