Airsane discards backend without scan area options (ricoh2
)
#123
Comments
Thanks! |
Yes, I guess the default value would be Letter or A4 for most devices. |
eSCL will now announce a max scan area width of 216mm (US Letter) and a max scan area height of 297mm (A4). That should accommodate for most cases. I need to ask you to test with the Ricoh scanner because I don't have such a device available. |
It detects the scanner now but fails to scan. Can't tell whether this is an AirSane fail or just the backend, will debug further in several weeks. P.S. also just wanted to be sure that you have received my emails and not interested in the donation. |
Thanks for debugging it. Regarding the donation, "not interested" would not be quite accurate. I just don't think it is the time now. |

Full log (spoiler)
Airsane does not accept printers which backend does not supply scan area parameters. One of such backend is
ricoh2
.SANE documentation states that the frontend MUST accept scanners with this parameter missing.
