If you can’t find an epson scanner when using scanimage -L you may want to run this short applescript that kills the Epson scanner process. Turns out it opens the scanner in exclusive access and doesn’t let it go.

A variant of this may work with other brand scanners also.
-- Kill any Epson monitor that is running in exclusive mode
    set results to (do shell script "ps -xww  | grep 'MacOS/EPSON Scanner'")
    set AppleScript's text item delimiters to {return & linefeed, return, linefeed, character id 8233, character id 8232}
    set results to text items of results
    set AppleScript's text item delimiters to {""}
    log (count of results)
    set firstLine to item 1 of results
    if ((count of results) > 2 and firstLine contains "MacOS/EPSON Scanner") then
        set pid to word 1 of firstLine
        set results1 to (do shell script "logger 'Forcing Epson Scanner to quit, PID: '" & pid)
        set results2 to (do shell script ("kill " & pid))
        set results3 to (do shell script ("logger 'Epson Scanner not running'"))
    end if
end try
