Yes the Epson GS drops a crap ton of ink every six hours. We had a tech come out and change the cleaning cycle to a lighter cycle and it saved a ton of ink and the printer is yet to get clogged. You may want to change the type of cleaning cycle.
Don't know what ours is set to, but after 1 year, still more than half full all cartridges, replaced the starter ones fairly soon after purchase though.
