There are many, many, many Epson owners in the same boat. Many
equivalent bugs opened tagging libusb, sane, udev, etc. as the culprit. There
has been no resolution to my knowledge. Just go to Google and search for "Epson scanner bugs Ubuntu" or something similar and you can read all about it. I even added a bug in Launchpad. I thought I had it fixed by going from my USB 2.0 to my USB 1.1 bus but it eventually started having the same hiccups.

For the record, I have the same scanner as you and it exhibits the same
symptoms. It only behaves if I power off/on the scanner after *every*
scanner operation. Slows down workflow immeasurably. Used to work fine
in the old days of hotplug and started to go off the rails when hal/udev was
instituted. Either this is way down the priority list or everybody is
too busy blaming each other to figure it out.
