Photoshop :: Printing Out Of CS5 On Epson R3000 Prints Light Cyan And Grey Background

I have an Imac with Mountain Lion, CS5 and have just replaced my Epson R2400 with an R3000. Now the white background round the image is covered in small cyan and light grey dots. If the image fills the paper, then the margin is affected. But when trying to proof colours I am going through loads of paper as I cannot now print a smaller image on a larger piece of paper, then re-feed the same sheet through with another small image as the paper is now pale blue.
 
The R2400 was fine for proofing, as the image alone would print and then the printer fed through the remainder of the sheet without printing, leaving the rest of the paper white. I understood from that , that it was most likely a Photoshop issue and some sort of conflict with the Paper profiles. But, I have checked the profiles on my Mac and they are all version 2 profiles. I note that the few profiles that do work without the blue colour do have 'bkpt' in their profiling and that the ones for the paper I actually do use and in fact the majority of the profiles, do not contain 'bkpt'.
