Problem confirmed for the GT-9700 (aka Perfection 2450) with both the epson and epkowa backends. Note that these same backends work fine with the GT-8200 (aka Perfection 1650) under identical conditions. Just starting a SANE frontend (tried with xsane and iscan) with the GT-9700 already takes "ages" and it just refuses to preview. BTW, the epson backend is from sane-backend-1.0.14 and the epkowa one from iscan-1.8.1. # The upcoming iscan-1.9.0 (due 2004-06-18), which adds support for # the ES-10000G (aka Expression 10000) and adds saving in JPEG format, # suffers from the same problem.
