Multipage PDF in xsane -- "Failed to start scanner"
I'm trying to scan a multipage document into a single PDF using xsane. The first page is scanned correctly (I can verify the image) but as soon as it's completed, I get the message "Failed to start scanner. Device busy." If I try to scan again, it rescans page 1 of 3 rather than page 2 of 3, and doesn't incorporate it into the first PDF. (The scanner is a CanoScan LiDE 25, but I don't think that matters.)
I think I know what's going on, but I don't know what to do about it. When the scanner finishes scanning page 1, it takes a while for it to move the lamp back to the starting position. During this movement, the scanner returns a busy status (I assume), which ends the process of constructing the full PDF.
I need to be able to do two things: pause the process while I put page 2 onto the scanner bed, and cause page 2 to become part of a single PDF file. Is that possible?
