I'm using Kodak RA4 in an Ilford ICP42. Image wise I am not having any trouble, but I am having an issue with foaming in the developer. This is Kodak RA Developer Replenisher RT mixed per Kodak's recommendations with starter. I also replenish it.
The foaming is causing me to stop and clean developer out of the input roller area, which is supposed to stay dry. If I lift the top plate in the tank it's very foamy.
I only run RA4 through this, and it has had many washings and chemical changes since it was setup for Ilfochrome.
Also, I run a mix of Kodak Endura and Fuji Crystal Archive papers.
Any ideas on fixing this?
