Ok, great! In order to debug the 600 and 1200 dpi, I will need the traces produces by the driver in debug mode.
For that: - Recompile the driver with debug information: $ make distclean $ make - Set the Sane debug variable to full debug mode , and run xsane from the same console, to get the debug infos: $ export SANE_DEBUG_PIXMA=10 ; xsane - Then scan with xsane at 600 dpi, you should get lots traces in the console of what's going on. - Put all this stuff in a text file, zip it, you can send it directly by email to me (without sending to mailing list), I'll check that. Then, I propose to send you some different files that will include additional debug code, in order to better understand what's going on Rgds, Nicolas Le dimanche 10 f?vrier 2008 ? 23:37 +0900, Gernot Hassenpflug a ?crit : > On Feb 10, 2008 11:24 PM, Gernot Hassenpflug <aikishugyo at gmail.com> wrote: > > > > Now I will try to integrate the driver into xsane, and also see how it > > does with scanning larger areas up to A4. > > Good news, using xsane I could scan an L-size photo and an A4 page in > full colour at 300dpi. anything above that works for a short while > before being cancelled by the hardware.
