Hello,
after searching the debug data, I think there is no problem in start
position
detection (which is correclty reported to be 'top = 65'). In fact it seems
that it is the value added to the detected y position is bogus. Currently, we
add -2.0 mm which may lead in a negative y movement if the inital y offset is
low.
So I think you should try to tune this value to exactly match your
scanner.
In the geometry settings, chage 'Start of scan area in mm (y_offset)' to a
value like SANE_FIX (1.0), and decrease it until the scanned picture doesn't
miss the very top of the scanning area. Since scanning succeeded with an
offset (-t 2), a value of SANE_FIX(0.0) should work.
In this cas we could keep the y size of area at 297 mm.
in genesys_devices:
static Genesys_Model hp2300c_model = {
"hewlett-packard-scanjet-2300c", /* Name */
"Hewlett Packard", /* Device vendor string */
"ScanJet 2300c", /* Device model name */
GENESYS_GL646,
NULL,
{600, 300, 150, 75, 0}, /* possible x-resolutions */
{1200, 600, 300, 150, 75, 0}, /* possible y-resolutions, motor can go up to
1200 dpi */
{16, 8, 0}, /* possible depths in gray mode */
{16, 8, 0}, /* possible depths in color mode */
SANE_FIX (-2.0), /* Start of scan area in mm (x_offset) */
SANE_FIX (-2.0), /* Start of scan area in mm (y_offset) */
SANE_FIX (215.9), /* Size of scan area in mm (x) */
SANE_FIX (297.1), /* Size of scan area in mm (y) */
