I have 2 of those I work with daily and I am not a fan. The Green inks are inconsistent in color and Epson really wants to force owners into using their tech service providers by making parts harder to come by. I haven't shopped printers in awhile and just been inheriting them with the different positions I take. All that being said I'm sure my company will force me to continue using them when we need another printer simply because it's what we already have.
Aside from the inks and service issues, the printers perform well for what we use them for. I need to turn off my green channel so I can have better color consistency on images with heavy green. Of course I could just make color adjustments daily, but I don't have time for that and I'm the end user so I have final say on quality.
I'd recommend that you stay as far away from the GS6000 as possible. We have one and it has been nothing but trouble since day one. We run a Roland XC540, a Canon ipf8300 and the GS6000, and neither the Roland nor the Canon have given us one percent of the trouble the Epson has. My company has already decided never to purchase another Epson product again.
I told the last repair tech who was here for the GS6000 that I wished we had just gotten another Roland. He said that I would be amazed how often he hears those exact words.
Hope this helps.

The problem is Epson must not have any field techs, sub-contract to printer/copier repair people.sounds like you need a new tech.
