sane-find-scanner -q
found USB scanner (vendor=0x04a9 [Canon], product=0x190f [CanoScan]) at libusb:002:012
First I want to mention that I am perfectly satisfied with the perfomance and usabilty of lubuntu especially with old, lowend Laptops. I am thankfull to all those people which make this great distribution possible. For all my problems so far I found a solution (I am on board since lubuntu 12.04), however the following I could not fix myself.
I expect that the backend genesys (part of libsane) used with the scanner LIDE 220 allows me to read scans directly with libreoffice or gimp to the respective application.
What happens:
Libreoffice "sees" the scanner, however I cannot select the resolution. First it is 75 any other selection ends up in 4800. I can read one scan in resolution 75(?) the next scan results in a libreoffice crash. Errors are eratic. But libreoffice is unusable with the backend genesys.
Please note unpluging the LIDE 220 and plugging Epson 1640su scanner (backend epson2) everything works as expected and I can scan as often as I will with any resolution I choose.
Gimp does not include either xsane ore xscanimage as plugin if the LIDE 220 via genesys is active.
however the plugins are found and active if I use for example a Epson 1640su (backend epson2) and I can scan everything.
Remark:
genesys works perfectly with scanimage, xsane, xscanimage, Simple scan.
I can only guess that the interface of the backend genesys has a flaw, which makes interfacing to libreoffice and gimp impossible. I would not expect the error on the Libreoffice or gimp side, since both work with epson2 backend happily. Confusing is, the genesys works perfectly with the frontends
scanimage, xsane, xscanimage and SimpleScan. I would look for the flaw in the way the resolution is communicated back and force from the frontend to the backend. However, I do not know details about the sane API.
Remark1: I played the game also with the 32Bit version of Lubuntu 16.04.1 LTS In that version the backend
genesys does not work correctly at all. Black scans, the scanner makes awfull noice. Upgrade to rolfbench version 1.026 of libsane makes only scanimage work, but xsane and other do not work at all.
again everything works as expected if I use the Epson scanner via backend epson2 (no need to upgrade to rolfbensch version 1.026 of libsane).
