The CTD Unit is a Sensor on or near the Transfer Belt Unit on your Dell Laser Printer. This error is advising that the sensor is dirty and may need cleaned. If you receive one of these errors please clean the CTD Sensor on the Printer.

My printer is not new, but I just replaced the PHD unit and received the same error. To fix it I had to clean the CTD sensor.

This link explains how to do that:

If it's not blinking it one of: The PHD (Print Head Device), or belt unit, life is coming to an end. Clean the CTD sensor. Try to clean the CTD sensor with a dry cotton swab. The sensor is located on the front cover (inside).

I've included a link below to the manual for your printer. Please follow the instructions listed under "Cleaning the Automatic Density Control (CTD) Sensor".

CTD (not CDT) stands for Color Toner Density Error. Your bad sensor is not on the printer, but on one of the color toners.
