[sane-devel] [hp5590] PATCH: enhance allowed ADF image height

[Juanito Hunter]

Good work to Manuel and Ilia!  I hope to try the patch myself this weekend.

Juanito

P.S.  Manuel gets the same error with paper longer than about 14" as I do with Windows.  Also, the HP documentation correctly states that the ADF will scan both sides of letter (or presumably A4) but won't do legal.  It gives the same "Paper Jam" message, even though there is no jam.

Hi Ilia, and Juanito i did the following tests today

For the test I draw rules on the pages for reference.

Before apply the patch:

Hardware Specs:
Operating System: Ubuntu
 10.04 32bits
Scanner: HP5590

Software:
Sane version --- >  1.0.14-9 (From the repos)
sane-backends --- > 1.0.20 (From the repos)
Frontends: scanimage, xsane, simple-scan, gscan2pdf.

Pages Tested:
Size: 215mm x 297mm --> All OK, no errors
Size: 215mm x 304mm --> error the page exceed the
 height Y limit
Size: 215mm x 356mm --> error the page exceed the height Y limit
Size: 215mm x 381mm --> error the page exceed the height Y limit

After apply the patch:

Hardware Specs:
Operating System: Ubuntu 10.04 32bits
Scanner: HP5590

Software:
Sane version --- >  1.0.14-9 (From the repos)
scanimage (sane-backends) --- > 1.0.22 (From the source, and patched)
Note: I had to uninstall the old sane-backend to avoid versions conflicts the other method not work for me, something miss 
Frontend: scanimage

Pages Tested:
Size: Letter (215mm x 297mm --> All OK, no errors
Size: LetterS (215mm x 304mm) --> All OK, no errors
Size: Legal (215mm x 356mm)
 --> All OK, no errors
Size: 8.5X15 in (215mm x
 381mm) --> Output image height is ok up to (14.25 in), the rest in blank and results paper jam.
I guess pages sizes greater than Legal  will give the same result

However for me, it works and it's all I needed Ilia, so really really thanks for you support 
Any help that you need to try something ..just let me know..

Best
 regards

Manuel, Panama

Juanito, Manuel,

thanks for your feedback.

Most easiest way is to get SANE backends snapshots from
http://www.sane-project.org/snapshots/, the file will be named
sane-backends-gitYYYYMMDD.tar.gz.

Next, to quickly experiment without touching system libraries, you
could use the following procedure installing SANE backends in a
temporary
 place:
- unpack them to any directory
- cd to that directory
- apply this patch using 'patch -p1
 <  sane-backend-hp5590-adf-height.diff'
- configure && make
- make DESTDIR=<some dir> install. The backends will be installed into
<some dir> - that could be $HOME/tmp or anyhing you prefer
- prepend LD_LIBRARY_PATH to
scanimage/xsane/whatever_frontend_you_prefer to point to that
directory. Eg. (assuming you ran configure with --prefix=/usr/local
and that you installed backends into $HOME/tmp):
LD_LIBRARY_PATH=$HOME/tmp/usr/local/lib SANE_DEBUG_DLL=255
SANE_DEBUG_HP5590=255 scanimage <rest of command line>. SANE_DEBUG_DLL
will give you a chance to see how backends are loaded and you could
verify their locations (should be from $HOME/tmp/usr/local/lib in this
example)
- try to scan from ADF
