[sane-devel] Genesys backend update to Dec 06, cvs

[Gerald Murray]

Hi all,

# These tests results are using sane-backends-20051206-cvs:

GL841 - Canoscan lide35:

This has changed for the worse since Nov 24.
I have previously made scans at 150, 300, 600, in color.
Now the 'image' is no longer recognizable.

color, 75dpi, (scan fails, obtaining 0 feed steps, then stops)

color, 150dpi (unrecognizable image created)
warmup(?) is very odd.
move head, wink lite, park head <-repeated several times.
Usually a warmup would keep the light on, move to strip, scan, rescan if
necessary.  I am not sure where this is coming from.
flag GENESYS_FLAG_SKIP_WARMUP is still there.

color, 300dpi -  SAME as 150dpi

color 1200dpi - Very slow, backtracks 195 times on a 107mm scan length.
image size was 100 megabytes, for about 1/3 of the available scan area.
(Note: using usb 1.1 fullspeed, not hi-speed)

GL646 - HP 2400:

The inconsistent response from the device is no longer a problem.
The frontend code still does not work, so no image.


Stef:

Thanks for your comment on the "no warmup will succeed" area.  I had
not thought about that.   I will continue working on it, my pace is
rather slow, and I am missing the log that would show values to test/try
in the registers, as I am only using Linux to work with.
I am willing to do some tests with mine.  Not knowing the range of values
that are workable does pose some risk to the device here.

best regards,
Gerald
