Question about Dell 2135cn All-In-One Laser Printer
Posted by Anonymous on
Hi. Easy! Open the front cover and you will see two stickers with red borders in front of you. About 10mm above them is the sensor - dust it with a cotton bud or tissue.

Cleaning sensor with a Q-Tip did the trick--thanks for the good advice! Actually I had to slightly moisten the Q-Tip to get all the dust. I also needed to turn the printer off and back on to reset it after cleaning.

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".

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.
