I quite certainly get further than I did before -- on my initial test run, the scan began and proceeded 3/4 of the way through the page before halting -- but an unfortunate incident involving a cup of water terminated my experimentation before I could do further testing or execute a run with logging enabled.
Should the scanner decide on Monday that it's inclined towards operation, I should be able to provide more detailed information then. (Should a service manual describing full disassembly and reassembly be available, as opposed to the one I found online which which described replacing only some of the most readily accessible parts but *not* such critical areas as the board underneath, I would be most appreciative of a pointer in its direction). "--mode=Halftone" results in "scanimage: setting of option --mode failed (Invalid argument)". Also, I note that "startbutton" hasn't been replaced with simply "button", as needed to work with the button-daemon.
