Question about Epson Aculaser C1100 Printer
Since the CX11NF uses a single Drum(Photoconductor) unit with 4 separate Developer units the only possibility here is a pit or similar defect in the surface of your Photoconductor Unit. What you are seeing is a small defect spot in the drum that is attracting toner where it should not. If you are making a black only page then you will only see a black spot because the color developer units are not used. However, when making a color print the other developer units are used and thus the colors spots appear. 27 years of printer experience tells me that there is a 95% or better chance the problem is in the Photoconductor unit. They are expensive so I know this is not great news.
Good Luck and Thank You for using Fixya.
