[SOLVED] Scanner Problem after update

business_kid · 02-25-2021, 04:39 AM

I thought my update (Current 2020-09-28 updated to 2021-02-11) had gone perfectly, but it seems I lost the scanning function on my HP Laserje MFP130 scanner

Code:

scanimage -l
Output format is not set, using pnm as a default.
scanimage: open of device hpaio:/net/HP_LaserJet_MFP_M129-M134?ip=192.168.178.103 failed: Error during device I/O

I get exactly the same error from opening xsane.

I'm not au fait with scrapping with scanners, as this thing always worked, so there was nothing to do. The scanner is on 192.168.178.103. I can ping it, and anyone on my home network can print on it, such that it's the only printer in the house now (My son got sick of buying inkjet cartridges). All the libs seem present, the only oddity I can find is that xcam exits with a segfault

There is no specific file in /etc/sane.d that obviously refers to it, but there was none last time either - the thing just worked.

Any ideas what to try next?

Maybe stupid idea; Did you try reinstalling it (i.e. setting it up anew) via cups, maybe all kinds of stuff have changed in the mean time? Or does it only works via sane??

Has the package sane-1.0.31-x86_64-3 been upgraded ?

business_kid · 02-25-2021, 07:33 AM

Thx for reply.

The printer/scanner/fax sits on the network. Cups can print to it; so can windows. I have no issue with cups so see no need to reinstall it.

I have just used sane, which reads it off the network. Is there something else?

EDIT:@BrunoLafleur: the packages are

Quote:

/var/log/packages/python-sane-2.9.1-x86_64-2 /var/log/packages/sane-compat32-1.0.31-x86_64-3compat32
/var/log/packages/sane-1.0.31-x86_64-2 /var/log/packages/xsane-0.999-x86_64-4

They have all been updated although the versions are nearly all identical. I can tell by the dates

BrunoLafleur · 02-25-2021, 07:42 AM

xsane call sane which has xcam you said is segfaulting. That's why I think about it.

Maybe some packages were not updated correctly ?

I use scanners with sane / xsane / gimp and they works well (HP Photosmart 5525 and HP Envy PRO 6430).

There is hp-doctor utility in hplip package, have you tried to run it?

business_kid · 02-25-2021, 09:21 AM

@BrunoLafleur: I did a full backup of the original install and that xcam segfaults also

Thx anyway.

I'm really just a scanner user, but I ran it. Some interesting results

Polkit is there. I'm guilty as charged on avahi. They seem to have vanished.

It appears to have puked near the end for the lack of PyQt4. I did grep the iso ChangeLog.txt for it, and it appears to have been removed

If it's a 'must-have' I can bang it in again. Is it?

Ignore Qt errors, Qt is optional.

business_kid · 02-25-2021, 10:17 AM

I installed PyQrt-4,12.3 before I saw your comment
Optional for sane maybe, but it stops hp-doctor thusly (even with PyQt-4.12.3 installed)

Code:

Traceback (most recent call last):
  File "/usr/bin/hp-doctor", line 297, in <module>
    num_errors, num_warns = dep.validate(DEPENDENCY_RUN_AND_COMPILE_TIME, False)
  File "/usr/share/hplip/check.py", line 367, in validate
    self.__update_deps_info(supported_distro_vrs, dep,
  File "/usr/share/hplip/check.py", line 210, in __update_deps_info
    installed_ver = self.core.version_func[deps_info[6]]()
  File "/usr/share/hplip/installer/dcheck.py", line 303, in get_pyQt4_version
    from PyQt4 import QtCore
ImportError: cannot import name 'QtCore' from 'PyQt4' (unknown location)
bash-5.1$

Avahi is not a part of Slackware... I believe it just allows the hp utility to scan the network for printers.

Emerson · 02-25-2021, 10:35 AM

Strangely enough hplip seems to depend on it in Linux. I have an HP printer/scanner. When I purchased it I logged into its web interface and turned off a few things, including automatic network discovery. After that I started looking how to get it working, and it did not. Totally desperate I installed Windows 7 into VirtualBox and it was able to print and scan. So I knew the hardware was good. I got it finally working, but I learned the hard way automatic network discovery is not optional for Linux driver, it must be enabled. Which hints avahi isn't optional, either.

PyQt4 needs qt4 which is no more in Slackware current since KDE5. It can be put aside qt5 but take some resources to compile (2 Go /tmp and 1 hour on a 8 thread machine).

sane has been recompiled but maybe there is some problems with the new stack ot the current.

I can't test because I have kept KDE4 and Qt4 and have no KDE5 on my latest Slackcurrent. I recompiled my KDE4 like said in other posts.

Now you know why I keep isos

. I have qt-4.8.7 from the 2020-09-28 iso. That went in, but didn't help much. I think it may have got further along, but I'm not sure

Code:

Traceback (most recent call last):
  File "/usr/bin/hp-doctor", line 297, in <module>
    num_errors, num_warns = dep.validate(DEPENDENCY_RUN_AND_COMPILE_TIME, False)
  File "/usr/share/hplip/check.py", line 367, in validate
    self.__update_deps_info(supported_distro_vrs, dep,
  File "/usr/share/hplip/check.py", line 210, in __update_deps_info
    installed_ver = self.core.version_func[deps_info[6]]()
  File "/usr/share/hplip/installer/dcheck.py", line 303, in get_pyQt4_version
    from PyQt4 import QtCore
ImportError: cannot import name 'QtCore' from 'PyQt4' (unknown location)

I don't have the machine for big compiles. I don't need to fix qt, just the scanner.

What version of hplip you have there, I have 3.20.11 and it is happy with Qt5.

I have 3.20.6, from 10 days ago. It would be unusual to shift QT versions with such a small version bump, but I'll update hplip first thing tmw, remove qt4 & PyQt4, and post results. It's late here.
