Description rob verduijn 2012-03-01 10:10:52 UTC
Version:           0.7 (using KDE 4.7.4) 
OS:                Linux

Hello I have a brother dcp-7065DN which has a flatbed scanner with an automatic document feeder.

Scanning a single page using the automatic document feeder works fine.
But when I wish to scan multiple pages only the first page is saved.

I tried setting the following options:
Save location : /home/rob
Name format: Image-

Save mode: Save without asking for a filename
skanlite  saves only the first page.

Save mode: Open the save dialog for the first image only.
skanlite still asks for a name and saves only the first page.

Save mode: Open the save dialog for every image.
skanlite asks only for a name once and saves only the first page.

Reproducible: Always

Steps to Reproduce:
start skanlite
place multiple pages in automatic document feeder
select scansource 'automatic document feeder'
select save mode 'save without asking for a filename' (or whatever other one you like since it doesn't make any difference)
scan documents

Actual Results:  
the first page was scanned and saved
I don't know if the other pages are scanned as well since I have no idea how to check that.

Expected Results:  
all pages should be scanned and saved

don't hesitate to ask me for other details if you need them

Unfortunately I do not have a scanner with ADF.

The reason you do no t get all the pages scanned is probably that the scan source name/string is not recognized by libksane as a ADF. That means that the batch scanning is not activated.

Can you run this command:
scanimage -A -d <device>

Where <device> is the devie Id that you get when runing  scanimage -L.

Then copy paste the output to this bug.

The output from the commands is below.

Are you able to compile and test libksane from git? I think I can fix the problem quite easily, but it needs to be tested.

Comment 4 rob verduijn 2012-03-07 19:23:54 UTC

I've looked into the git source from libksane and what is in the libksane.src.rpm, and they are not even remotly alike. Obviously it's a long way from git source to rpm package. Without some serious studying (more likely weeks than days) of the kde ways of packaging or the ways of git compiling I cannot compile it. I'm not completely green with compiling stuff, but I definitely need some help and explanations to compile likksane from git.

Comment 5 Kåre Särs 2012-03-07 19:51:26 UTC
# Get the latest code
git clone git://anongit.kde.org/libksane

# Compile 
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=debugfull ../libksane
sudo make install

The above requires that you have KDE development packages installed. On ubuntu you can install all build dependencies with:
sudo apt-get build-dep libksane

I'm not sure if there is something similar on openSUSE...

The line to change would be ~line 919 in libksane/libksane//ksane_widget_private.cpp
Change :
            if (source == "Automatic Document Feeder") {
            if (source.contains("Automatic Document Feeder")) {

Hope this helps

Comment 6 rob verduijn 2012-03-07 21:37:47 UTC

In opensuse you can install the kde-development libraries with:
zypper in -t pattern devel_kde
Or check the kde-development pattern in the yast installation gui.

The scanner now scans and saves every page  ( jay :-)

Great work.

Comment 9 Michael D 2015-09-10 13:34:16 UTC
This isn't working for me in Kubuntu 15.10 using Skanlite 1.1. ADF Simplex just scans the first page, even though all pages are fed through the sheet feeder.
Comment 10 Kåre Särs 2015-09-10 19:00:32 UTC

Can you do the same as Rob did in comment 2?
