Cleaning the CTD Sensor on a Dell 2155cn/cdn Laser Printer


The CTD Sensor measures the consistency of Toner on each printed page. During general usage an error may be displayed on the Printer's LCD Display advising "Clean CTD Sensor" or "CTD is Dirty".

This generally occurs when Toner traces have been left on the sensor and the printer is unable to read the information from the sensor.

If a CTD error message is related, please follow the guide below for instruction on cleaning the CTD Sensor:




  1. Ensure that the printer is turned off

  2. Pull the standard 250-sheet tray out of the printer about 200mm

  3. Hold the standard 250-sheet tray with both hands, and remove it from the printer

  4. Push the side button to open the front cover

  5. Open the belt unit


  6. Clean the CTD sensor inside the printer with a clean dry cotton swab

  7. Close the front cover

  8. Insert the standard 250-sheet tray into the printer, and push until it stops

  9. Re-start the Printer and verify that the error has now cleared

  10. If the error is still displayed, after thoroughly cleaning the CTD please contact Dell Technical Support via the Twitter button below
