I'm wondering whether that status is reported by the device half-way through an on-going scan. If the backend passes that through to the scanimage as soon as it is received, instead of continuing to provide image data until the image is complete (status value of 5) first, you would get the behaviour you mention. > The scanner scanned the first sheet ok, placed it in the output tray, > partly pulled in the second sheet, and then stalled, while at the same > time signalling on its display that it is busy and having WiFi traffic. > It ignored any buttons pressed and had to be power-cycled. > > I know about the existence of environment variable "SANE_DEBUG_BJNP" but > have no idea what value to set it to to provide reasonable information. > Could someone please guide me? Just set it to 127 if you don't know. The developers should be able to slice and dice the result as needed.
