scanimage (sane-backends) 1.0.31-248-gfc74de7c5; backend version 1.0.31

Ricoh SP 3710:

tsayao at CO85635:~$ SANE_ESCL_DEBUG=255 scanimage -d 'escl:
https://172.18.15.247:443' > test.pnm
Output format is not set, using pnm as a default.
scanimage: rounded value of br-x from 216.408 to 216.408
scanimage: rounded value of br-y from 297.349 to 297.349
