HP Envy 7640 cannot be detected by HPLIP 3.15.2

Hi,

Can you please try running command 'hp-setup' in terminal to configure the printer.

Let us know if the printer is detected and configured.

provide us 'hp-scan -i -g' command output ?

New question #262136 on HPLIP:
https://answers.launchpad.net/hplip/+question/262136

After the latest HPLIP upgrade on my PC workstation running Ubuntu 14.04, the above printer (connected by USB) can no longer be detected by HPLIP.

1. The printer was set up earlier about a month back with an older version of HPLIP on Ubuntu 14.04 and both printing and scanning worked fine then.

2. Even after the problem with HPLib,  the printer can still print using the previously configured printer driver from applications like google chrome and Libre Office. CUPS can detect the printer properly

3. XSane can no longer detect the printer hence I cannot use the scanner anymore.

4. Results of checks as follows:

Hi,

Running hp-setup gives an error message: error: No devices found on bus: usb

Running hp-scan -i -g gives the following:

I replaced the models.dat file from the 3.15.2 distribution and it fixed the problem. Thanks

Hi Wong,

Why did you have to replace the models.dat file? Upgrading to the latest hplip version should have copied this file there. Did you see any error or warning messages during upgrade?

Thanks,
Suma

Not sure what happened, I used the Ubuntu software center to remove and install hplip, but somehow the software was upgraded to 3.15.2 but models.dat was a much older version.

I did not get any specific error messages during that particular update but had previous periodic updates with error messages, none specific to hplip though.

OK. Thanks for the clarification.

Regards,
Suma

Hi, with the latest Ubuntu yesterday (1-Aug), the file models.dat was corrupted and I lost my printer model 7640 from the file again. The file has been updated as 30-Jul-2015 but looks like the backup file I had of the 14-May-2014. It appears the version control on this file has some problems?

Hi Wong,

We will surely took into this issue and try to reproduce it in our lab.
But you can manually download the latest hplip-3.15.7.run file from http://hplipopensource.com/hplip-web/gethplip.html and run command 'sh hplip-3.15.7.run' in terminal to install the package.

During the installation it would ask for user input :
Do you want to ('i'= Remove and Install*, 'o'= Overwrite, 'q'= Quit)?
choose 'i' (Remove and install)

This should successfully replace the models.dat with the latest.

Thanks,
Goutam
