[SOLVED] Scanner on raspbian (Wheezy) server stopped working

floppy_stuttgart · 03-12-2017, 02:28 PM

Hello,
I have a printer on my raspberry pi (as printer-server connected via LAN to the house router). The printer works: I can print from clients (laptops connected via wifi to the house router).
The function scanner dont work anymore (on server, on clients).
I checked all advices (again) from here https://wiki.debian.org/SaneOverNetwork
My experience came from that installation where I was already successfull http://www.linuxquestions.org/questi...on-4175488989/

Code:

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.
  # Also you need support for SCSI Generic (sg) in your operating system.
  # If using Linux, try "modprobe sg".

found USB scanner (vendor=0x0424, product=0xec00) at libusb:001:003
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

  # You may want to run this program as root to find all devices. Once you
  # found the scanner devices, be sure to adjust access permissions as
  # necessary.

scanimage -L (on the server)

Code:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

A bit weird: the scan-find-scanner say it found 2 scanners on the server. I will further dig into that issue. perhaps here http://www.tldp.org/HOWTO/Scanner-HO...eshooting.html
Any advice/help is welcome.

Are you using HPLIP? If so, what does the following diagnostic report?

Code:

hp-check -t

The problem is you're using the wrong CUPS backend. You should be using the hp backend, so the URI in /etc/cups/printers.conf should look like this

Code:

hp:/usb/Deskjet_2540_series?serial=CN49Q4F4KH0604

The scanner hpaio backend can only work if the printer is configured to use the hp backend.

Any idea?

ferrari · 03-15-2017, 04:10 PM

Yes, I already told you the answer in post #4. Your printer backend is incorrect. (That doesn't affect the printer operation, but it will affect the scanner operation as hpaio relies on the hp backend being configured.)

So, this URI in printers.conf

Code:

DeviceURI usb://HP/Deskjet%202540%20series?serial=CN49Q4F4KH0604&interface=1

needs to be changed to something like

Code:

DeviceURI hp:/usb/Deskjet_2540_series?serial=CN49Q4F4KH0604

and then restart CUPS.

Alternatively, delete the existing printer configuration and use hp-setup to reconfigure.

floppy_stuttgart · 03-16-2017, 02:44 PM

DeviceURI hp:/usb/Deskjet_2540_series?serial=CN49Q4F4KH0604 was not working too. So its why I was asking what was a working link (I should have said I already tried it).
For the reason I am connecting with ssh to the server, "hp-setup -i" say

Okay, with the printer attached try running the hp backend manually like this

Code:

sudo /usr/lib/cups/backend/hp

What is returned? If the printer is not enumerated then there is a problem with the USB cable or subsystem that needs investigating.

floppy_stuttgart · 03-18-2017, 03:34 AM

the installed hplip was 3.15.4.
My printer HP Deskjet 2544 can only be supported from hplip 3.15.9 according the hplip page (I forgot this from the previous install I made months ago http://www.linuxquestions.org/questi...11-4175541344/ ) = the current standard debian Wheezy package 3.15.4 of hplip dont support my printer.
So, I downloaded the latest hplip version according http://hplipopensource.com/hplip-web...os/debian.html (I have the raspian which is based on Wheezy).
And it looks much better now:

the installed hplip was 3.15.4.
My printer HP Deskjet 2544 can only be supported from hplip 3.15.9 according the hplip page (I forgot this from the previous install I made months ago) and the current standard debian Wheezy package 3.15.4 of hplip dont support my printer.

Ah, that is good to know. Always a good thing to check first - I was thrown by your initial comments about the printer working...

I have a printer on my raspberry pi (as printer-server connected via LAN to the house router). The printer works: I can print from clients (laptops connected via wifi to the house router).

The printer worked with the CUPS standard installation.
The scanner function only works with a different hplip version > debian wheezy standard version (the printer works)
