[sane-devel] Cannot scan over an open local network
Joel,
I wrote the tutorial you are using, so I want to make sure we get your
issue fixed and the tutorial updated.
I added some of the things from this topic to the tutorial.
Can you give us an update on if you got this working?

First of all, thank you for all of your hard work getting SANE to be...sane.
I recently acquired an HP Deskjet 3050A J611 series, which is one of their
all-in-one printer/scanner combo machines.
I would like to be able to use the device over my home network, where the
device is connected to our file/print server. I can print to it everywhere
(from windows linux machines alike) with no problems, but I cannot scan
from anywhere but from the server itself. It works flawlessly from the
server, but I cannot even see the machine over the network.
I have followed the advice on the
https://help.ubuntu.com/community/sane.d%20tutorial page and have worked
through all of the troubleshooting steps three times to make sure I didn't
miss anything.
I can't even scan through localhost on the server it's connected to. All
firewalls are disabled across all machines on the internal network.
The file/print server is running Ubuntu 12.04.
Are there any further steps I can take to figure this out?
For lack of a crystal ball ;-), posting your /etc/sane.d/net.conf and
/etc/sane.d/saned.conf files as well as information about your network
configuration would be very helpful in trouble shooting this. For the
network configuration, the output of
$ sudo ifconfig
or
$ ip addr
will do.
There is a small chance that saned may be run by a user that is not in
the appropriate group. To check that, run
$ grep setfacl /lib/udev/rules.d/*-libsane.rules
$ groups saned
and check that the bit between g: and :rw in the output from the first
command should be listed in the output of the second. In my case, the
output looks like this (Debian wheezy)
ENV{libsane_matched}==yes, RUN+=/bin/setfacl -m g:scanner:rw
$env{DEVNAME}
saned : saned scanner
and scanner is both lines so I'm good.
Other than that, check that saned is running with
$ sudo service saned status
Hope this helps,

[sane-devel] [PATCH] Fix MX892 interleaving issue at high resolutions.

Thank you for bringing this to our attention. Nice to know that both 1200 and 2400 work without extra image data manipulation necessary too. I've sent a patch for this issue to the list, so hopefully that can be included shortly. Any thoughts on the timeout issue? Simply changing the timeout value in wait_until_ready() seems like a hack. Also, it doesn't solve all of the starup issues - if the printer has been sitting for quite a while unused, other errors show up: [sanei_debug] Setting debug level of pixma to 3.

Likely unrelated, I'm using the -d flag to scanimage, so why is sanei_bjnp_find_devices() still sending out discovery messages over the network? Thanks, --- Henry Ptasinski henry at logout.com

I have the above MFD and would like to use the scanning facility with SANE. Does anyone know if this is do-able, if so how? Regards Neil
[sane-devel] Fwd: canon lide 110 - buttons - don't working :/
hi guys, i'm new here i tryed some 'solutions' to use buttons on canon lide110 but no one worked i searched about sane-genesys and buttond but i couldn't make it work can anyone help me allowing this device to accept buttons and send me information when should i start scanimage? maybe we need to add some code but it's not a problem for who don't know the device it's a canoscan lide 110 (sane-genesys) it have four buttons PDF, AUTO SCAN, COPY, EMAIL i just need one button, but if we could make all work that's nice too :) thanks guys -- Roberto Spadim
