Bug 428056

Thanks for the report.

Can you run skanlite with debugging enabled?

from a terminal run:

SANE_DEBUG_DLL=128 skanlite

And then attach the output to this report.

I am assuming that the scanner is supported by the hpaio backend so maybe a more interesting debug log would be to run Skanlite with the following command

SANE_DEBUG_HPAIO=16 skanlite

(and attach the log to this report)

Thanks,
  Kåre

Created attachment 132607 [details]
Output report for first debug command

Created attachment 132608 [details]
Output report for second debug command

There are 3 instances of the Scanner and Printer that are detected. Only one of the 3 allows Skanlite to open, but returns the "Invalid Argument" error as described in the initial thread.

Thanks for the logs!

Did you try scanning with the hpaio logs? I did not find the reason for the "Invalid Argument".

Could you add a log with a higher debug value for hpaio (you can play with the level to see where you start to get interesting oputput) 128 is the highest if I remember correctly...

Regards,
  Kåre

Hi.

These logs don't seem to bring up any further information ...
user@user-HP-Pavilion-m6-Notebook-PC:~$ SANE_DEBUG_HPAIO=128 skanlite
[sanei_debug] Setting debug level of hpaio to 128.
[hpaio] sane_hpaio_init(): scan/sane/hpaio.c 349
[hpaio] sane_hpaio_get_devices(local=0): scan/sane/hpaio.c 370
[hpaio] sane_hpaio_get_devices(local=0): scan/sane/hpaio.c 370
[hpaio] scantype=5 hp:/net/hp_color_laserjet_mfp_m277dw?ip=192.168.1.6&queue=false
[hpaio] sane_hpaio_exit(): scan/sane/hpaio.c 364

I wonder if there is something missing in the SANE drivers of Skanlite installation?

Perhaps if you can guide me through uninstalling the drivers and Skanlite and reinstalling, it may start to work? Note that I have installed the Printer part through "System Settings" and this is working fine (Maybe my "suggestion" is because I have been too long in Windows environments).

Please try the hplip package and then run "hp-setup printer_ip".
(or hplip-gui for GUI)

For m277dw, you probably need hplip + the binary plugin for scanning support.

Thank you very much ... this link together with your previous message did the trick. I had some trouble initially, so removed all previous installations of the printer.
1. Connected the MFP using the printer USB cable.
2. Waiting for the computer to do its auto-detect thing.
3. Then from the console>hp-setup
4. On the first pop-up, brings up a 2nd pop-up.
5. Following the instructions on the second pop, where I was prompted to choose the correct Wifi as I have 2 routers. Just before this completes, there is an instruction to run hp-setup printer_ip.
6. On the first popup, even though it says step 1 of 3, I selected Cancel, because Next started the process again.
7. From the console> hp-setup printer_ip
8. Three printers are installed (1 printer, 1 fax, and 1 scanner).
9. I am unable to select the HPLIP Device Manager as it gives an "HPLIP Status Service: Unable to locate hp-toolbox on system PATH"
10. But I can now use Scanlite for scanning and can print from other programs.

Thank you for you assistance.

You are welcome.

If you want to use HPLIP Device Manager GUI, you may be able to solve this by installing hplip-gui.

Thank you everyone for your assistance - My HP MFP printer and scanner works with an HP Device Manager GUI. Since these threads are used by others, I will add my step, which continues from Comment 8.
11. Application Launcher -> Applications -> System -> Muon Package Manager.
12. Enter "hplip" into the search bar (the search is automatic as you type).
13. hplip and hplip-data are shown as "installed", but hplip-gui is shown as "Not Installed".
14. Select the hplip-gui line, then click "Installation" (Newbies, don't be surprised if nothing happens).
15. Click the "Apply Changes" near the top of the window, and the installation runs to completion.
16. Application Launcher -> Applications -> System -> HPLIP Toolbox.
