There is a gscan2pdf user with a Epson DS1660W which is behaving
strangely (in my opinion).
If the user sets the brightness or contrast to any value other than 0,
then at the next scan, the scanner return SANE_STATUS_CANCELLED. Setting
the non-zero value itself returns SANE_STATUS_GOOD
However, he is able to scan successfully with scanimage.
The bug report is here:
Apart from the above, other strange things are that the device name
starts as follows:
the return codes bitmask is includes undefined bits, e.g.
which I am interpreting as
? + ? + ? + ? + ? + ? + SANE_INFO_RELOAD_PARAMS +
SANE_INFO_RELOAD_OPTIONS + SANE_INFO_INEXACT
Has the backend implemented an extension to SANE? Does it therefore ship
its own version of scanimage?
Any insight welcome.
