This scanner can not be shared on the network when connected to a Mac. It has least reliable paper pickup mechanism than any (HP, Xeros, Ricoh, ...) ADF I have seen in my life. The driver (last version for OSX dated June 2009) is awful and routinely crashes. It locks up with as yellow light on power button at times, and nothing, but pulling the power cord, resets the scanner. In the two years I have it I do not remember being able to scan more than 30 pages in a row without a problem.
