That's good news. As of November 4, 2013, Epson updated the Scan Utility for the Perfection V300 Photo with version 3.5.5.0.

For those of you that believe Apple's Image Capture is a satisfactory substitute, you are completely wrong. Apple's Image Capture is a basic scanner utility with no features. It offers no PDF compression and scans PDF files at a ridiculously large file size. Epson's scan utility offers far more features and Mavericks was not usable without it, especially when people scan documents as part of their workflow.
I quickly removed Mavericks because of this. I also removed Mavericks because it is completely foolish of Apple to force people to hold the Command key to open a folder in a new window, or even to open in a tab which they advertised as their new feature. Two-handed operation is not efficient. Right-clicking and left-clicking to open a folder in a new window is not a solution. Apple needs to restore the basic functionality of Finder windows that existed since 1984.
