I have a Dell C2665DNF (Total printed pages 17,000), and in the past 2 days, is printing as follow:
-Magenta is coming as a "Dark Brown",
-Cyan is not a solid color, since it shows a soft foggy presence of "light Magenta almost closed to white".
-Black and Yellow seem to work very well.
This analysis is the result of a test made by printing a document with each one of the 4 primary colors, and based on solid color lines, and capital-bolt text,.
So far, I have made the following mantainance, without achieving any better result :
1)Replaced Magenta and Cyan toners
2)Removed all removable parts ( e.g. toners, drums, fuser) and cleaned the printer with compressed gas duster
3)unplugged the printer for 5 minutes to reset the memory
By removing the drums, I have noted a very small presence of Cyan powder in the inlet of the Magenta drum (under the transparent sliding lid). A similar issue seems to be on the Cyan drum.
Please, is there anybody that can help me?
