No it does not.
While it shares similar print head and dampers to the 3880 it does not share an ink pressurization system.
No Epson printer has an ink agitation system.
Some Canon models do.
I’ve also read about those “features”, and while the pressurization one may not be accurate, the cartridge may provide the agitation you’re mentioning through a passive system described by Epson here http://www.youtube.com/watch?v=kTh_u4FPbCg
