Unable to connect to scanner

Hardware Support

Hello,

I installed Zorin 16 yesterday. I have the HP MFP M148fdw all-in-one printer.
I am able to print. But when I try to scan, it returns the message window 'Failed To Scan. Unable to connect to scanner.'

Here are the hardware and peripheral device results of a couple Linux commands below:

I downloaded the Zorin Hplip drivers for my HP all-in-one. But I don't know if I want to download all those drivers if the printer works fine. What is the next step to troubleshoot this?

I installed the GUI package. Then I attempted to install the plug-in 3 times and it seems to be saying I am entering the wrong root superuser password. I know I entered the correct one. Root password is the same as Zorin log-in password......correct? This is the response I got from terminal.

(By the way, printer works ok
But still no scanner.)

note: Using PyQt5
error: License agreement not accepted. Exiting.
error: Python gobject/dbus may be not installed
error: Plug-in install failed.

Done.
error: Failed to install Plug-in.
Either you have chosen to skip the Plug-in installation or entered incorrect Password.

Have you tried sane-airscan package?

Thanks for the suggestion. But I'm not interested in sane-airscan. I want to find out why this plug-in won't install. Maybe I never granted myself root access?

I'll have to look at this again Thursday night after work.

Why do I need 'superuser' root password to install a plug-in? In fact, I don't see any need at all for an administrator root password. No one else uses my desktop PC. I think the key here is to eliminate or bypass root administrator password. Just get rid of it. There is probably a terminal command to do this. I'll check.

While not a definitive answer, this is what I've found works for me...although unfortunately I have to do this everytime I want to use my scanner.

(ensure the scanner is switched on)

Right click the desktop and select open in terminal.
Type sane-find-scanner then press enter.

If your scanner is found then in the list of text that comes up you'll see something like this...

found USB scanner (vendor=0x04a9 [Canon], product=0x1802 [TS5000 series]) at libusb:002:005

In this case the numbers needed are the libusb:002:005

Now type sudo chmod a+rw /dev/bus/usb/002/005 (or whatever numbers show for your scanner)

Now, try scanning and it should work. As I scan once in a blue moon then this is a workaround that works for me when I need to scan. I'm not saying it will work for you but it's worth a try!

Hope this helps.

Andy.

Because installing anything to Root requires root privileges. Anything installed on Root can affect your Whole System.

Type in all those terminal commands every time I want to use the scanner....no thanks. I'll keep looking for another way.

You should not need to type in a bunch of commands every time you need to use the scanner.
It would be a one-time thing.

Gday @turnawrench ,
No.

In most Distro's the Root account isn't configured.
So you will need to add a p/w to use root privileges.

To set root p/w (password)
1st test if you have root privileges type

su

then try your p/w.

if it returns "failed", then next type.

sudo -i

Enter your login p/w.
When successful then enter:

passwd

Now enter the new Root p/w.

It should say "Successful", To test this use:

su

Then enter your new root p/w.
