I meet the same bug with gscanpdf
gscan2pdf: sane_start: Invalid argument
My system is:
* Ubuntu 20.04
* Scanner: Brother MFC-J1010DW
I read a lot of post and I try an another file : numériseur de document (simplescan perhaps) and I find that the scanner works perfectly.
I suspect there is a bug in gscanpdf in some situations (I use gscanpdf for a long time even with some other brother scanners without problems)
