I bought this to replace an R800 that was showing banding on photos and which the local Epson service agent was unable to fix.
It was easy enough to set up and the prints look great. I used genuine Epson ink and premium glossy photo paper with Photoshop colour management (the software installation automatically added the R2880 colour profiles to the Photoshop print menu). Blacks are particularly good - the R800 blacks had a warm colour cast. Bright colours are possibly slightly better in the R800 but there's not much in it. However, the R800 was very poor at printing dark greens.
Speed is very slow on max quality setting but on standard setting much faster and I couldn't see any difference in quality - even under a magnifying glass.
However, I was very disappointed when, after 3 days, I did a nozzle-check. The printer went into an extended cleaning cycle and then showed that one of the nozzles was blocked. I did another nozzle check and again it did a cleaning cycle before printing the nozzle check pattern. This appeared to use around £12 worth of ink, although it's difficult to tell as the ink-level window doesn't give a very accurate display - earlier versions of the printer status monitor at least had graduation marks against the displayed ink levels.
There is no printed manual supplied and the electronic manual doesn't mention this behaviour. I've now seen similar complaints in the US Amazon web site.
Next time I did some printing the problem didn't happen and the nozzle check was fine, so maybe this is just a teething problem.
So overall, I am happy with it but a bit nervous of the apparently random cleaning cycles and the amount of ink that gets used as a result - the R800 would check the nozzles and then give the option of nozzle-cleaning or not. Especially disappointing as Epson are supposed to have improved the nozzle and ink technology so why so many cleaning cycles? Then again, if it makes the printer last longer than my R800, perhaps it is worth it.
Summary:
Very good colours
Excellent blacks and greys
Good speed on standard quality setting
Max quality setting appears to be no better than standard setting
Worrying, unpredictable and expensive automatic nozzle cleaning (not described in the manual)
No printed manual.
Although I have not used Epson's support service for this printer, experience with previous printers have left me unsatisfied.
