Hi David,
We had this exact same problem with our 5500 a few months back. After several
phone calls to Epson Tech Support we were unable to resolve the problem and
since the printer was still under warranty (by less than 2 months) I insisted
that it be replaced. It was and so far the problem has not recurred.
The good folks at Epson lead me to believe that one else had ever reported such
a problem. And up until now I had no concrete reason to doubt that. Apparently
that is not the case however. Perhaps others on this list can 'testify' to
similar problems???

Hi all,
I was searching the ColorSync archives and came across this post.
However, I was unable to locate anything further, no cause and
apparently no solution.
I have had similar problems, a few months ago the same issue happened to
me. I am running an Epson 7000 with the Epson driver using the
Generation Micro Bright Inks, MacOS 9.2.2, Photoshop 6, and the profile
is built with Color Vision ProfilerPro and read on a DTP41UVT. I am
printing on German Etching Paper.
Everything was working fine and then my results shifted to an over all
green cast. I checked the profile and from what I could tell it seemed
fine, I then rebuilt the profile from the saved text file of the
original measurements. Still the green cast persisted.
I ran my standard test file each time and it was looking awful. With no
apparent clue I reprinted all the patches and built a completely new
profile. This cleared up the problem but did not answer the question as
to what had caused the drift in the first place.
Now, after using this new profile for a few months I am once again
experiencing drift - this time the prints are shifting to the magenta side!
Since there is no way to relinearize the printer I was going to reprint
the patches yet again and start over. In the process of all this I
noticed I still had the measurement file from the first profile so I
decided to build a profile from the old and original set of numbers and
now this is looking great again!
I am using Adobe RGB and the Postscript Color Management setting in the
print dialog window and also using the Saturation setting in the
ColorSync settings window for the Epson driver, where I choose my custom
profile.
Has anyone else experienced this vexing problem? Anyone have any clues
as to what might be causing the shift?
Thanks for the help.
