Yes, but my recent experiences with the R3000 have shown me, that the ink lines need to be completely flushed once a year. Epson did not see fit, to give the R3000 replaceable dampers. So, yearly flushing seems to be the only practical alternative. Such flushing could run up the waste ink counter quite quickly---even though I am using an external waste bottle.
Of course, i could just flush the system, by printing pages of color patches. I estimate that it would take about 8 8x10 photo sheets of solid swatches, to fully recharge all of the lines. And, using prints, I would not be running up the WIC, or placing stress on the heads with cleaning.
