Epson 835 prints with a lot of red, especially in B&W prints

​Hi,

This isn't a color cast as much as huge patches of bright red.  My work flow is to shoot RAW (Sony NEX7), convert to JPG using either ImageDataConverter or ACR, convert to B&W using either DxO or NIK.  Color space is the default,  I have to check it.  Paper is Costco Glossy.
