Not sure if it is exactly the issue you are having but I had a machine that the printhead went bad and the colors were coming out really different than they were supposed to. Like yellow looked orange type of thing so that is where I personally would start.

Thanks. That was my 1st thought that the inks were mixing in the printhead--crossing the center membrane or partition or whatever it is. But instead of purple looking, I think it would be blue-green colored since purple would be due to blue and red mixing. But I know that can happen--leakage between halves of the printhead. Once on a Z3200 I got orange ink from the M-Y printhead and once on a T770 I got purple from the M-C printhead.

Earlier it printed a beautiful print using I think chromatic blue, so I don't think it's screwing up print jobs, but maybe that blue was made up of cyan. Will have to watch it.

Had the same happen to me on a Z6100.

I ran the "color calibration" on the "bright bond"--in the printer I entered some type of "glossy photo" to get it to do the "color calibration". There was improvement. Purple and what appears to be more chromatic green were more vibrant.

Perhaps the purple in the diagnostic image is just inherent, don't know.

Chromatic blue still looks purple. Maybe it is a matter of having the right paper. I did not want to go to the trouble of obtaining and loading glossy photo.

Also, color calibration got rid of some banding in some of the yellowish grayish print on the same paper.


Thanks.

The blue always looks purple. That's normal.
