I have the R3000 and initially experienced the same situation. There is a maintenance cyle the printer goes through and I was told by Epson that it is important to have the printer connected directly to a wall connection rather than a power strip shared with other devices. As I understand it the other devices can potentially "confuse" the R3000 and cause it to go through its maintenance cycle prematurely. Once I changed the power connection the issue went away. I get the impression (just conjecture on my part) that the complete purging of air from the ink tubes after installing the cartridges for the first time in a new printer may take a few cycles of purging. Certainly my initial cartridge install took a lot more purging than any of the replacement cartridges later.
