HP LaserJet Pro MFP M28-M31 does not scan HPLIP 3.18.12

Scan and look at the journalctl output. Anything?

Thank you for your answer!

Here are the error lines only:

Hi amasterov,

I have just been dealing with a user with the same device as you have and who has a scanning issue. It would be very, very useful to know whether any of the three techniques mentioned at

work for you.

Thanks,

Hi brian_p,

Turning AirPrint off does not help. Screenshot of printer's settings is attached. The error messages are exactly the same as with AirPrint enabled.

Modification of models.dat eliminates "no attributes found" error, but scanimage -L shows another entry:
[alex@alex-ub Загрузки]$ scanimage -L
device `v4l:/dev/video0' is a Noname USB2.0 HD UVC WebCam: USB2.0 HD virtual device
device `hpaio:/net/HP_LaserJet_MFP_M28-M31?ip=192.168.0.227' is a Hewlett-Packard HP_LaserJet_MFP_M28-M31 all-in-one
device `hpaio:/net/laserjet_mfp_m28-m31?ip=192.168.0.227&queue=false' is a Hewlett-Packard laserjet_mfp_m28-m31 all-in-one

And scanning does not work with I/O Error.
Errors in journalctl (models.dat modified):

Thank you very much, Alex. Apart from a plugin problem (which we can do nothing about), I cannot see a way to a solution for non-scanning with this device. The only other thing might be to try turning Bonjour off as well as AirPrint.

Windows from virtual box scans OK.

I have tried to get tcpdump of scanning with Linux host and compare it with the same from Windows host. The difference is that if HPLIP gets 503 http return code it throws an error, and Windows when it gets 503 retries in 100 ms. That's the difference as far as I understand.

Hi Amasterov,

This issue is seen as if we did not enable “ Enable Remote User Auto Capture “ option in the EWS page of the device.
Once we enabled this option, we were able to do the scan.

To enable the option :
1) Connect the device and PC in same network
2) Open a Web browser, and in the address field, type the device IP address exactly as it displays on the Configuration Page, and then press Enter.
NOTE: If the Web browser displays a message indicating that accessing the website might not be safe, select the option to continue to the website. Accessing this website will not harm the computer.
3) On the top navigation tabs, select the Security tab.
4) In the Web Scan Auto Capture Jobs, select the Enable Remote User Auto Capture check box.
After that restart the device (i.e., printer/scanner)

Thanks,
Umesh

Hello Alex,

Is Umesh's advice a solution to your issue?

Hello Umesh and Brian!

Unfortunately I do not have the security tab on the top navigation tabs.
I have the Security setting in the Networking tab, but there is no "Web Scan Auto Capture Jobs" or "Enable Remote User Auto Capture". May be the solution is for another model/firmware
The screenshot is atthached

Thank you for that, Alex. Your observation is repeated in bug 1811504. It is hard not to see this issue as involving some interaction with the ESCL part of the plugin and the solution lying there.

Consolidating multile reports about scan problems with LaserJet Pro MFP M28-M31 to bug #1811504 as it seems to be the most advanced and even has a workaround.
