Comment 85 for bug 424249

Some more comments:
1. My scanner is an Fujitsu 1300 ADF. The automatic document feed and multipage PDF support is the reason I'm using gscan2pdf instead of Skanlite or Simple-Scan (my hardware works with those programs, but they're very limited).
2. I've tried the workaround of adding "resolution = 600" (or whatever) in the end of ~/.gscan2pdf, to no avail.
3. I've uninstalled the default Trusty version of gscan2pdf and installed the package "gscan2pdf_1.2.3-0~ppa1saucy_all.deb" from the PPA jeffreyratcliffe/ppa. Didn't solve the bug, so I've reinstalled the default version.
4. I can save the scan results as a series of .PNG images, without problem.
5. I've tried to save as djvu, but cjb2 returned the error "ERROR - Error writing image for page 2 of DjVu (process returned 2560, image size 0)".
