[Bug 844582] Re: "Invalid argument" when trying to scan

2021-03-15 Thread Jeffrey Ratcliffe
@PaulHazelden (tenuki57):

I don't see "invalid argument" anywhere in the log. It looks to me that
SANE did not find any scanners. Was your scanner plugged in?

What does the following return:

scanimage -L

?

I then tried the next suggestion:
scanimage -x 210 --mode=Color --resolution=300 --batch

and this succeeded.  If I attach the '--log=' option to this command
line, will that generate any useful information?

2021-01-31 Thread Fernando
Hello,
I have the same problem:
   gscan2pdf: sane_start: Invalid argument

I run from the command line with the "--log=log" option and create the log.xz 
file that I attach.
My system is:
   * Kubuntu 20.10 (Ubuntu + KDE)
   * Scanner: Brother DCP-J562DW
I've been able to use this scanner in al ubuntu versions (I'm long linux user 
and gscan2pdf too), but I'm not sure if I've used with the previous 20.04 
version (I think that yes).

I have another PC with Windows 10 and the scanner works. So is something
with my system not with the device.

I have the same problem.

gscan2pdf: sane_start: Invalid argument

I would agree that scanner support is the responsibility of the
manufacturer, except that my system ran perfectly until I upgraded from
18.04 to 20.04.1.  So whatever the manufacturer supplied used to work,
but the upgrade broke it.  It seems to me that in this situation, Ubuntu
ought to try to fix it.

2018-03-12 Thread Rolf Leggewie
Hans, we can certainly disagree.  But it seems you as well as some of
the upstream devs do not understand much about packaging.  If you want
timely fixes, pay someone to do it.  If you want to make a mess of your
system, install random packages.  I'm fine with any of that.  I'm not
fine if then such person comes back and waste Ubuntu devs time with a
problem they did not create or gives Ubuntu a bad name that they did not
deserve in this case.  I hope that makes sense.

BTW, scanner support is the responsibility of the manufacturer, don't
you think?  Have you complained to them about lack of FOSS support?
Have you taken this into consideration when you purchased your scanner?
Or have you simply purchased whatever was cheapest?  IMO, what is not
acceptable is buying cheap, unsupported stuff and then complaining to
people doing a LOT of work for you for free.  Last comment, if you feel
that all of this is so unacceptable then have you rolled up your sleeve
and provided a patch or at least tried to?

Rolf, I would agree with you if bugs would be fixed in a timely manner,
but that is not the case.  In the meantime, people go months if not
years with a scanner that does not work.  That is unacceptable by any
standard.  People should see my previous comment as a work around to get
things done.  This bug was opened in 2011 and still affects people.

Please do not suggest to install third-party packages, even if from the
upstream developper.  It is a very bad idea in almost all situations.
The real problem is how to distinguish those situations from the ones
where it might be OK (for the ordinary user).  Thus, the normal user
should stick to the official packages.  We need to get rid of the
impulse to install random stuff from the internet to quickly "fix" a
problem.

I had a similar problem with the default version of gscan2pdf available from 
the default Ubuntu 16.04 repositories.  I would scan, but the error message 
would arrive after the scan was completed. 
 gscan2pdf version 1.3.8.

I then installed the following PPA to get the latest version, 1.8.3:

sudo add-apt-repository --yes ppa:jeffreyratcliffe/ppa

The problem was gone.  I suggest you upgrade gscan2pdf to the latest and
report your findings.  We might be able to close this ticket.

2015-07-07 Thread Jeffrey Ratcliffe
As you have noted, the 001:005 refers to the usb device. However this
can change between boots. Did you reboot between the gscan2pdf/scanimage
and epson sessions?

As you can reproduce this from the commandline with scanimage, I am
transferring this bug to sane-backends, as the bug must be in the
epson/epkowa backend in SANE.

Invalid argument, is simply the error code that libsane returns.
Unfortunately, it does not provide any more information that that by
default.

However, you can run scanimage with debugging turned on. I would ask on
the SANE mailing list for more help.

When I use Epson's own scan software it works fine. I notice that the
epkow:interpreter selected is different than the one gscan2pdf is
choosing.

gscan2pdf chooses: epkowa:interpreter:001:005
epson proprietary chooses: epkowa:interpreter:001:004 see screenshot

I get the exact same error from gscan2PDF with my HP 7510 all-in-one
scanner. (see attached Video). On two different computers. (note using
the HP scan utility works)

For the earlier Epson. The Epson ScanImage for Linux also works
normally.

Is there a better explanation what Invalid Argument is referring to in
the error handling?

I'll make a log of the HP output later today.

2015-06-30 Thread Jeffrey Ratcliffe
The fact that you can reproduce this with the scanimage frontend tells
me that this is a problem with Epson SANE backend, and not with
gscan2pdf. If you look at the bottom the last log you posted, you will
see that this is the command gscan2pdf used:

 scanimage  --device-name='epkowa:interpreter:001:005' -x 210 -y 297
--adf-mode='Duplex' --resolution='200' --batch --progress --batch-
start=1 --batch-increment=2

Please try this from the command line and confirm that it throws the
same error.

If so, this bug should also be attached to the libsane package, where
the epson and epson2 backends are.

I have a similar problem with a different scanner. The Epson GT-S80.
When I choose Doublesided scanning also Invalid Argument.

I'm using Ubuntu 14.04.2LTS with the PPA running version 1.3.0

I've run a log file and attached it here below.

These Entries in the log seem odd.

WARN - Argument  isn't numeric in numeric ne (!=) at
/usr/share/perl5/Gscan2pdf/Dialog/Scan/Sane.pm line 731.

WARN - Argument  isn't numeric in subroutine entry at
/usr/share/perl5/Gscan2pdf/Frontend/Sane.pm line 430.

INFO - sane_set_option 51 (auto-eject) to  returned status Success with
info 0
