Please update on Feeder usability- does it work?

[markosjal]

I tried this a while back and had a comment posted here was told the sheet feeder did not work. That I think was over a year ago. That comment was still active and I added a reply to a couple days ago asking if the feeder now works but now the whole thread seems to have disappeared.

Please clarify sheet feeder functionality

[markosjal]

I ask this because I have a Brother MFC2760 that has never been able to use the sheetfeeder via AirSane. The Brother is using the SANE-AIRSCAN driver with WSD protocol. I just upgraded to debian 11 on Pi 3B+ and the result is the same . I only get the first page. Just tested on OSX 10.15 and Mopria again. Does not matter if I save as PDF or JPG the result is the same., with only getting first page.

I know this is a problem. In the meantime, I got helpful information about this issue in #109, so I may be able to fix it.

[SimulPiscator]

In the latest commit, I have modified AirSane to improve behavior with ADFs. Please give it a try.

[markosjal]

Ok I updated earlier today probably within an hour of your post and It did not work . I had no time to troubleshoot till now

here is the status of airsane Service

So I then went to
http://10.0.0.250:8090/eSCL/ScannerCapabilities

and see this in a web browser
`Error 404: Not Found

when processing request:

to hell with inserting code on here! Nothing seems to work.

[markosjal]

I thought I would add the following which may be helpful. I wont even try to enter it as code as it never seems to work anyway!

scanimage --help -d 'airscan:w0:Brother MFC-7360N'
Usage: scanimage [OPTION]...

Start image acquisition on a scanner device and write image data to
standard output.

Parameters are separated by a blank from single-character options (e.g.
-d epson) and by a "=" from multi-character options (e.g. --device-name=epson).
-d, --device-name=DEVICE use a given scanner device (e.g. hp:/dev/scanner)
--format=pnm|tiff|png|jpeg|pdf file format of output file
-i, --icc-profile=PROFILE include this ICC profile into TIFF file
-L, --list-devices show available scanner devices
-f, --formatted-device-list=FORMAT similar to -L, but the FORMAT of the output
can be specified: %d (device name), %v (vendor),
%m (model), %t (type), %i (index number), and
%n (newline)
-b, --batch[=FORMAT] working in batch mode, FORMAT is out%d.pnm' out%d.tif'
out%d.png' or out%d.jpg' by default depending on --format
This option is incompatible with --output-file. --batch-start=# page number to start naming files with
--batch-count=# how many pages to scan in batch mode
--batch-increment=# increase page number in filename by #
--batch-double increment page number by two, same as
--batch-increment=2
--batch-print print image filenames to stdout
--batch-prompt ask for pressing a key before scanning a page
--accept-md5-only only accept authorization requests using md5
-p, --progress print progress messages
-o, --output-file=PATH save output to the given file instead of stdout.
This option is incompatible with --batch.
-n, --dont-scan only set options, don't actually scan
-T, --test test backend thoroughly
-A, --all-options list all available backend options
-h, --help display this help message and exit
-v, --verbose give even more status messages
-B, --buffer-size=# change input buffer size (in kB, default 32)
-V, --version print version information
Output format is not set, using pnm as a default.

Options specific to device `airscan:w0:Brother MFC-7360N':
Standard:
--resolution 100|200|300dpi [300]
Sets the resolution of the scanned image.
--mode Color|Gray [Color]
Selects the scan mode (e.g., lineart, monochrome, or color).
--source Flatbed|ADF [Flatbed]
Selects the scan source (such as a document-feeder).
Geometry:
-l 0..215.9mm [0]
Top-left x position of scan area.
-t 0..297.18mm [0]
Top-left y position of scan area.
-x 0..215.9mm [215.9]
Width of scan-area.
-y 0..297.18mm [297.18]
Height of scan-area.
Enhancement:
--brightness -100..100% (in steps of 1) [0]
Controls the brightness of the acquired image.
--contrast -100..100% (in steps of 1) [0]
Controls the contrast of the acquired image.
--shadow 0..100% (in steps of 1) [0]
Selects what radiance level should be considered "black".
--highlight 0..100% (in steps of 1) [100]
Selects what radiance level should be considered "white".
--analog-gamma 0.0999908..4 [1]
Analog gamma-correction
--negative[=(yes|no)] [no]
Swap black and white

Are you sure you have LOCAL_SCANNERS_ONLY=false in your /etc/default/airsaned ?

[SimulPiscator]

If you run airsaned from the command line, and don't specify the compatible_path argument, you will also not be able to access the first scanner at /eSCL.
I understand this is annoying, therefore I have now made compatible_path the default.

Well my new install of Bullseye is now crashed on my Pi. When I get back to reinstalling, will test again.
