Epson F6200 color drift

[fmallonee]

We have always used Epson 7880s converted to use sublimation ink, however we have switched over to Epson F6200s about a year ago. I thought that the color would hold better on the F6200's since they are made for sublimation, but the drift is way worse on them. It seems completely random, the color could hold for a month or two, or only for a week or less. With the 7880s the color would gradually shift over a few months but with the F6200 the color will dramatically change from one day to the next, or start drifting way faster than with the 7880s. Does anyone have any experience with this way too frequent color shift on the F6200's?

How often are you re profiling the printer and which ink are you using?

We use Epson ink. We have profiled the printers only once so far(less than a year ago). With our old Epson 7880's we never needed to re-profile them. On the 7880's we could just adjust the RGB raster curves under color transforms in Wasatch whenever the color drifted too far, which would usually only be at the end of each busy season(so after about 4 months-ish of heavy use). The F6200's however will shift dramatically sometimes overnight or over the course of just one week or so. However sometimes the F6200's color will hold for several weeks as well.
